Hi, can someone help me? I've been trying to display the clock program that this site gives us but when I verify it it says:

exit status 1 'LCDShield' does not name a type

Ce rapport pourrait être plus détaillé avec l'option "Afficher les résultats détaillés de la compilation" activée dans Fichier -> Préférences.

CAUTION: Do not use with the Arduino Pro - 5V !
The 3.3 v output is tied to the 5v output!
You WILL damage your lcd if plugged in to one of these Arduinos

Perhaps in a future revision the board could include a reset switch? Since this is one of those Arduino shields that has to be on top, it could be handy. (In the mean time, I suppose one could cut a trace and wire a jumper in order to turn one of the existing buttons into a reset switch...)

The red and black wires are wires to a battery used to power the arduino and shield.
To boost the brightness i think that you will need to mess with the"
LCDCommand(VOLCTR); // electronic volume, this is the contrast/brightness(EPSON)
//LCDData(0x18); // volume (contrast) setting - fine tuning, original
LCDData(0x24); // volume (contrast) setting - fine tuning, original
LCDData(0x03); // internal resistor ratio - coarse adjustment
LCDCommand(P_SETCON); // Set Contrast(PHILLIPS)
LCDData(0x30);" code in LCD Driver.c

Does anyone know what the red and black mystery wires are? It looks like those are for the LCD backlight driver circuit? I am guessing. I can get Mark's code to run, but it is very very dim. It is kind of crazy to sell an Arduino shield without any documentation or Arduino-specific code.
Any ideas how to boost the backlight?
Thanks.

1st error is "multiple definition of 'delay_ms'"
2nd is "multiple definition of 'LCDData'"
Some information, I'm using the Arduino Duemilanove ATmega 328

Hey! anyone have worked with this shield? I tried the example arduino code by mark but there seems to be alot of error. Mostly duplicated functions in the LCD_driver.c portion. Anyone can help me with it?

Interesting that this is an Arduino shield but there don't seem to be any/many apps or examples written to run this display on the Arduino. The example code is written in C++, and I'm not sure how to run this on a vanilla Arduino system...

How can I get this part?where can i buy it? I need your help.

I bought this shield for displaying text. The one I received is probably an Epson, since trying code with Philips only shows a black screen. Problem is that the text is distorted, I can vaguely indentify the size of the words, but not individual letters. This is with the lcd.setStr() function. It is possible to draw a circle with a line. What can be wrong?

i want to use the library´s Peter but i can not use it, i want to do the O-scope that is in this example please somebody help me mi email is jcvelasco@uniboyaca.edu.co

hello guys i need your help i have to do a project for my class in the college i need to graph a imagen in this lcd but i dont know how can i do it i saw the example in the library but i can not modify it thanks

hey guys i am new in the excelente page

i need you help ¡¡¡ i need to graph an imagen in the lcd color in arduino, and i dont know what is the procedure thanks fot your colaboration

I would like to use this on my Arduino Due.

The problem is, I do not know how much it outputs to the arduino pins, because the Due only supports up to 3.3v, and I am worried this will output more than that. Can someone please tell me how much this board outputs?

Hello,

I try to use TestPattern program in Example Arduino Library form Peter, and I have an error after compilation :

In file included from /Applications/Arduino.app/Contents/Resources/Java/hardware/arduino/cores/arduino/Arduino.h:213, from LCD_driver.c:27: /Applications/Arduino.app/Contents/Resources/Java/hardware/arduino/variants/standard/pins_arduino.h:43: error: expected identifier or '(' before numeric constant

Arduino Uno with Sparkfun color LCD shield

Thanks for assistance

Didier

HI everyone ! I have a Color LCD shields and arduino uno. I wanted to load a logo like sparkfun logo in sample code. So can any one suggest how to do so ?

Just wanted to mention that the official Arduino ColorLCDShield library does not work with the Arduino Due but the gLCD-Library by TCWORLD works great! ;-)

Is it just me or are the buttons stupidly sensitive? I've been using the Bounce library to try and de-bounce them but they still register inputs if I bump the board, and always register well before I feel the tactile "click". Anything I can do to fix this?

what is function of resistor R13? what if we dont use R13 resistor and directly short 5v to lcd backlight pin??

Is anyone still having high pitch noise coming off of the booster coil? I didn't think much of it until I could not get reliable analog reads from the analog pins. I discovered that the booster coil induced noise into the analog pins due to proximity. If you have a shield with a high pitch booster circuit then attach a 10mF capacitor across the 5v supply as close to the shield(if not soldered on)as possible to get rid of the hum.

Has anyone tried this outside? I am looking for a display I can put on my Motorcycle to show Gear, Voltage, Current and anything else I can think off.

Hi Toni_K, Well it appears that the github for the LCD Shield is read only for me. So I will email the files soon so you folks can update the library.

Thanks, Tony...

I am working on a software update with additional features to the Color LCD Arduino Library. My question is where should I submit the updated library files?

Thanks, Tony

Are there mechanical drawings available? I need to put this in an enclosure (with the Arduino board). I am looking for specific dimensions.

Thanks,

I have to agree with several of the comments below. This item is sub standard for what I have come to expect from Sparkfun. In my case, I'm running attached to a uno. The examples work, but there are garbage or noise lines all over the screen. They get worse as time goes on. I think it's probably a damaged display and not the code. Can anyone recommend a better ( more reliable ) shield with a display. I'm not picky, monochrome is fine for what I'm doing.

Ok. So im an engineering student getting used to arduino and picked up this shield.to play with. After an hour i got it to display 8 lines of random generated data. Next I used that code to update an existing program which controles a dc motor and propeller to achieve some desired life using a pid... Silly me though I forgot to check and see if a pin is being shared or not, one was and as a result my uno is messing up calling an avdr error, i believe that my serial port is fried though I could be wrong. So i fixed the code and tried it on my mega and it worked fine for a few hours of use. Then I got random characters showing and now the lcd is not showing anything at all, after just 4 hours of use. My question is what could cause it to fail? Also i soddered pins 2,3,4,5,8,9,10,11,12,13,gnd(top right),the teo gnds on the left, and the 5 and 3.3 volt pins. Is this excesive or nessicary. It looked like the schematic called that these are used.

This may seem like a stupid quesition but how do you use the buttons? They are wired to connect the arduino pins to ground when pressed. The standard way to use a button is to wire the pin to ground via a resistor and run +5V to the pin from the button, pulling the pin to HIGH when the button is pressed. For this board do I need to run +5V to the each pin to pull them HIGH by default and let the button pull them to LOW? Am I missing something?

Does anyone know where I can find a library for this screen that has a wrap or scroll feature for text, so that when I send the screen a char array it will drop every 15th character to the next line?

The github link gives a 404(same for the tutorial links). Use this one instead: https://github.com/downloads/jimblom/ColorLCDShield/ColorLCDShield-11-3-11.zip

The arduino library set's the digital pins as input which is ok, but it also enables the internal pullup resistors, which my lead to problems. (It almost drove me crazy)

It appears that the ChronoLCD_Color example has a bug. In the function displayDigitalTime the local var timeChar should be size 13 and index 12 should be set to 0 before the call to lcd.setStr.

One big problem was to get it running with arduino-1.0. So I changed ColorLCDShield.cpp and the ColorLCDShield.h.

+ColorLCDShield.cpp+

from #include "wiring.h" to #include "wiring_private.h"

+ColorLCDShield.h+

from #include to #include

I have set up ColorLCDShiled with Uno R3. I had to change WProgram.h to Arduino.h and wiring.h yo wiring_private.h in the code to resolve compile errors. Now the code is downlaoded but the display shows only 8 noisy grey lines and is flashing every 2 seconds. Looks like it restarts. (Example code ChronoLCD_color). With the basic 12 line code in the startup guide I get the 8 lines but not flashing. Is this a broken display? Any software issue?

I'm just getting started with this shield and I've gotten the examples to run. Does anyone know a good way to generate the pixel maps used by the library? I would like to incorporate different fonts.

Does anyone know if this is compatible with the Maple board?

Will there be any compatibility issues using this shield with a UNO R3 and a SF AM/FM shield (DEV 10342) also running on the SPI bus? I also intend to use a shield that will occupy the serial outputs (D0 and D1 (UART protocol if it matters)) and several TWI sensors which I assume will not interfere apart from potential power issues.

I like the LCD... works great with the MLX90614cf for Infrared images. Only problem I can print text... but cant seem to print a variable... Can anyone help?

Ugh, that last post got skewed. It should be P underscore in front of those commands at the end, not PPASET in itallics.
I got a little somewhere with the inverted colors. If you replace
LCDCommand(P_INVON); // invert display mode(PHILLIPS)
with...
LCDCommand(P_INVOFF); // invert display mode(PHILLIPS)
The colors are almost right
Edit:
If you go to the LCD_driver.h file and change invert the color values, it works. My display just seems to be a bit off set and the bottom line is not writable.
I wish sparkfun would write their own code for their own shields and actually maintain it when they change important components.

Alright.. I got some where with my phillips version. I have tried several libraries and they all seem to have small problems. I used the Jell LCD_Library from here:
https://github.com/Jell/LCD-Library/blob/master/LCD-Library.pde
(replace both the underscores with dashes!)
It worked better than the others but my contrast was way too high and I could not see anything unless I tilted the display. I opened the LCD_driver.c file, about half way down there is a function called void LCDInit(void) You need to replace
LCDCommand(P_SETCON); // Set Contrast(PHILLIPS) LCDData(0x50);
with...
LCDCommand(P_SETCON); // Set Contrast(PHILLIPS) LCDData(0x30);
The lower value will make the display readable. My next issue is that all of the colors are inverted... Ill update when I figure that one out.
By the way, if you come across the older LCD_Library, you need to uncomment the define PHILLIPS AND you need to comment out define EPSON at the top of the LCD_driver.h file and then if you get errors talking about PASET, CASET, RAMWR, you need to go through the LCD_driver.c file, look for where it mentions PHILLIPS functions (leave the EPSON ones alone) and turn them to P_PASET, P_CASET, P_RAMWR. There are a few spots that use the wrong types.. Hope this helps

Are there any good libraries for the Phillips version? I need a library that lets me print characters/numbers. The listed code from the top of this page works when changed from EPSON to PHILLIPS but the colors are inverted. Red is Blue, but White is White.
With the Jell library and its other variants, the back light is bright white no matter what color I set it to. I can see the text if I tilt the LCD to an angle though.
With gLCD library, the text is backwards/inverted..

---Library updated: 22nd Oct 2011---
If anyone is interested, I have created an Arduino Library for this. (I hadn't noticed there was an example library, so i made my own.)
gLCD Library on github

You just need to copy the gLCD folder inside the zip file to the 'libraries' folder in the directory where arduino is installed.
There are also two example sketches which explain how to use the library. In the Arduino software go to File -> Examples -> gLCD -> BasicFunctions (or TestPattern)
The library works with both Phillips and Epson controllers. It can't yet detect which one you have, so you have to specify that as part of the Init() command. See either example sketch for more information.
At the moment it can draw lines, boxes, and circles. It can plot individual pixels, you can control the colour (4096 colours), and print out text strings. There is also a built in test pattern.
There is also a function to set the contrast of the screen if the default value doesn't work properly.
Data for printing characters is now stored in the program memory, which frees up 480bytes of SRAM.
For phillips displays, the init() call has been changed. It is now:
graphic.Init(xOffset,yOffset,invertColour,1,mirrorX);
-(xOffset,yOffset) sets the position of the origin on the screen in case some pixels are cut off.
-invertColour reveses the colour values when true (i.e. if black appears as white, set this to 1.
-mirrorX reverses the x direction.
This change is due to some phillips displays displaying a mirror image.
I have also added a fast digitalWrite function to the library, which if turned on increases the refresh rate of the screen by a factor of 10.
In order to use this, you must define which port each LCD pin is on in the gLCD.h file. If you are using this sheild unmodified, then the library won't need editing, as the default port defines support this sheild.
To use the faster function with this sheild, this should be defined:
gLCD graphic(8,9,13,11,1);
This is as it was before, except there is a fifth variable, which informs the library to use the fast write.
I will be updating the library slowly, at the moment it is version 1.3

I've got the Philips working with Jell's library.
Put the contrast to 0x35 instead of 0x50 (in LCD_driver.c)
BUT... Is there a way to print a VALUE on the screen?
-With this line I can put typed text in the screen: LCDPutStr("text", 0, 4, ORANGE, WHITE)
Is there a command instead of LCDPutStr so i can use a value to print on the screen? for example: int AB=5 -> print(AB) thats shows 5 on the screen.
I would like to printout a analogRead value on the screen.
(With the nokia 3110 lcd it was no problem, but with this one?)
Hope you can help me out!

Eagle files?

on the board there is a kind of 10pins connector.
How do u call it?or how can find it?
thanks for help

Thanks - downloaded from your link and tried it, now I get 'LCDShield' does not name a type then it highlights LCDShield lcd;
I put the ColorLCDSHield.cpp and ColorLCDShield.h in the dirctory with the pde.
Any ideas ?

Just received 2 Auduino Uno and a the lcd color shield. Installed the 0022 version program, loaded and ran Blink, no problem. Put the color lcd shield on. Loaded the sparklcd.pde compiled and uplaoded it. Screen goes to kind of blue fuzzy back screen. Using external power supply and usb. Nothing getting too hot, backup light is on.
Read the comments here by Jimbo on Aug 3 and tried the code he mentioned but don't find lcd.init(EPSON) or lcd.INIT(PHILIPS).
So I found the define in lcd_driver.h and commented out the Epson line and uncommented the Phillips line. Now it won't compile and upload. Get "PASTEP" undeclared...
What next ? I look around and I'm not the only one with this problem. Is there any clear directions out there for this combo - it's implied here that it's supposed to work. Anyone
there try it ?
thanks.

I'm using this with the Uno.
This is the worst part I've bought from Sparkfun. The the backlight on the first LCD wouldn't turn on. Support asked me to short one of the resisters and the LCD turned on, and the demo app displayed. I would told to remove the resister and put a solder blob. I tried this and all the resister came off. Sparkfun were nice enough to send me a replacement, however, it had the same problem, and worst, a dead pixels covering about 5-10%.
I give up. I hate this product.

This is the first product I've purchased from SFE that left me really disappointed (and I've bought a good chunk of their catalog). Terrible contrast, no backlight when connected via USB, etc. I think it's just a lousy display, not any fault of Sparkfun.
If you want a bright little display, look at the 4D Systems serial OLED displays instead. Bright, crisp color with a simple serial interface.
And SparkFun - take a look at the 4DisplayShield 160 or similar to replace the color LCD shield, this one's a turkey.

I attached this shield to an uno and loaded the example code from Peter's library. I'm using usb for power.
All that appears on the screen is noise. Sometimes I can get darker noise, but it is always just noise. I tried creating rectangles inside each other too and I get nothing. Just noise.
Any thoughts? Anyone seen anything like this?

Has anyone tried this with a netduino plus?

hello, i got the code from Peter to work on my Arduino Mega 2560, but i was wondering how do i make my LCD display values read from certain sensors? i looked up in the files and there's no function for that. Thanks

Hi, I am a newbie student, currently assigned to do a project with this color lcd shield, basically I need to display the speed and timer kind of thing. Now I am having the problem of displaying the Numbers on the LCD. I have tried with using LCDPutChar command, but it will not display the number instead it shows the character that represent that number (eg. 65=A, 70=F). Is there anyway to display the variable numbers on this color lcd shield?
Thanks in advance.

Mark Sproul's driver works great, but it uses up most of the RAM to store the font.
I have a small patch that uses progmem save 1552 bytes of RAM.
See http://wa5znu.org/2011/05/arduino-sparkfun-lcd/
I would be pleased to see these results incorporated into the published libraries and code.

Does this shield work when you also use an ethernet shield? According to shieldlist.org, both shields use ports D10 through D13 as well as D4.

does this shield work with the LiquidCrystal Library?

I found a big problem with the LCD library and printing fonts. We were using this library in a medium size arduino sketch and were having it crash for no reason. The library uses a massive amount of ram for printing strings. I made some changes that will decrease ram usage 100 fold. The library has a couple of new functions and should be compatible with any projects built on the old library. There are still a couple of tweaks I would like to make but here is the 99% complete code.
LCD library fix

Just a quick question guys, on the LCD, next to the connector there are pin out labels:
5 -> 1
6 -> 10
but looking that the connection on the shield, according to this pins 2&3 are shorted, not 8&9 as the schematic suggests. Which way round are the pins on the connector? From my testing I believe they are:
10 -> 6
1 -> 5

Hi, I got that board, tried to use it with Arduino Uno powered by the USB connection, it is working except LCD is dark,
there is no backlight working.
Also at least one of resistors R3, R4, R13 is getting pretty hot. I can't distinguish which one exactly :(
I accidentally shunted R13 with my multimeter probe for parts of a second and backlight turned on immediately, and that one hot resistor cooled down quickly. When I turn board off and on again, it is the same story, backlight not powering...
Can somebody help me, please?
I don't understand schematics of voltage boost circuit to explain myself what is the problem.

Hi,
I just bought this Color LCD Shield via Lextronik in France.
I try to make it work on Arduino NG rev.C (ATMEGA168) without success.
I tried Peter's Library with sample and also tried the Mark's code. At beginning, the LCD stays blue. Then it displays something that is hard to see, it seems to display wrong colors with odd random lines and dots and odd characters. When I push buttons, I see there are changements, but images are still randomly distorted.
There's also some pixels (a little dapple) which stay pink all the time.
It looks like the problem described by "chh | August 12, 2010 at 11:32 AM".
I've got 2 assumptions:
- the LCD is broken.
- this shield is not compatible with the Arduino NG (perhaps because Arduino NG doesn't have a 3.3V output).
What is your opinions?
Thanks

I had the generic backlight not turning on problem with the Arduino Duemilanove. Tried to troubleshoot myself with no success. Would not work with USB or external power supply.
I contacted techsupport at sparkfun dot com it was great. They were fast to respond with several realistic tests, less than 1 hour during business hours. One of their suggestions worked (not suggested in any of the previous comments).
I typically avoid tech support at all costs due to past painful experiences, but in this case it was great. I would suggest anyone having problems should give support a try.

Alas, I'm pretty sure I also just got a board with a non-working backlight. In a dark room there is nothing seen.

Hi, The software examples all use the Lynch method of 12 bit addressing for color (RED is 0xF00 etc). All of the bitmap converters I have seen convert Red as 0xE0 etc so none of the colors show correctly. Can someone please explain to me how to use the latter. I think it is 8 bit, but I am unsure how to write the color as data and also how to use RGBSET8

I get nothing on the display on uploading the Example codes onto the Mega2560. I also changed the line#245 too..
But nothing shows up on my display :(!!!
I am very very sad! I god an SD shield+SD card, and this color LCD... neither working! :(!
I thought I had a problem with my Arduino.. I bought a new 2560.. I also tried it on the 1280 as well :(! no result!

Spankin' cool board.
I downloaded all of the code above for use on my new Arduino UNO board with this shield. All of the code worked - I had to fiddle the straight (non Arduino) code slightly to compile as a C project but that was trivial.
Here is my gripe.
Is this a case of NIH (Not Invented Here)? Every single one of these code bases picked a different "upper left" corner. Yup, three sets of "drivers", three different "upper left" corners.
What gives?
Surely there is a (0,0) pixel, and it is always in the same place, so why three different "upper left" corners?
Regardless, nice work everyone, all the code worked as advertised! I'm totally tickled here. Now to come up with a game or something!
Have fun,

I just got a Color LCD Shield for Arduino. Loaded the example code and library. Then I wrote a simple sketch that just displays analog channel 0.
The code and libraries work fine with UNO shield but do not work at all with MEGA. LCD does not show any output at all with same code that worked on MEGA (recomplied for MEGA).
Any suggestions? (Known issues with MEGA?)

Hi,
I have one of these, when I connect it to Arduino Mega and use Peter's code, but when I apply the power I get lots of fuzze pixels!
Also is Peter's code for Epson or Philips or both?
Thanks.

i have an arduino uno now
according to "TheMoogle" comment the does the LCD get damaged when i connect the 5v pin
when i connect only the 3.3v pin the LCD display only works with no back-light
when i connect the 5v pin both back-light and LCD works as it ought to
does it really get damaged? if so how to turn on the backlight it remains off when i connect only 3.3v pin and gnd.

Member171297:

i have bought this color shield (the exact same one)
near my locality because it was available
Q: how can i use this as the
Color LCD - Breakout Board
LCD-08600nokia lcd break out board
listed on your website
plz note that i dont use audrino i use other controllers
which pins should i ignore and which i should use for displaying (eg: for spi interface with 8052 running at 20mhz)
i'm a newbie plz bear with me if if u think my question is irritating.

Anyone have any experience combining this LCD shield with the sparkfun GPS Shield?

Check out the Christmas tree code I set up for the LCD Shield: http://peterdavenport.blogspot.com/2010/12/its-8-bit-christmas-charlie-brown.html

after reading about the power issues on the Pro I've been wondering if this shield would work with the Uno. Can anyone affirm this shield working on the Uno without any problems?
[EDIT]Additional question: Today was the first time I got to play with my LCD shield. I put Peter D's most recent example sketch successfully (i.e. verified/compiled) on my Uno, but I get absolutely nothing on the screen as if it wasn't connected at all. Help? Also posted in this forum thread.
[EDIT 2] Solved. A bit of rewiring did the trick.. Not really sure why, but thankful that it did. Thanks for this shield Pete!
Thanks in advance.

Can anyone tell me what pins this uses? In particular which analogue pins are still available for other shields?

I have this LCD working fine, but need to switch to something about 1.5 x 2.5" in size. Does anyone know a "drop in" replacement?

Prof Bob (et al): I, too, suffered long and hard through the "bad boards" saga. thanks for the fix. i wish I would have looked here before wasting so much time. lesson learned.

ProfBob: No Backlite boost voltage. Just received the board today and have the same problem as Ken-Hack. You can barely see the Sparkfun Logo. I checked the the voltage boost out at C3 on the schematic and it is 5V and not 7V as stated. The resistors next to C3 should be R1 = 3.3K and R2 = 15K, both on my board are 3.3K<br />
Can anyone verify the resistor values on a "working" board. Thanks<br /><br />

I got it working. You need to make a dirty hack to it, but it works. I wrote about it on my blog. Check it out: http://richardkaufman.org/blog/how-to-fix-it-backlight-on-sparkfuns-color-lcd-shield-not-working

Hi, I am using http://peterdavenport.blogspot.com/p/lcd-library.html. I can see proper output on the lcd but no backlighting. Is a call (pin enabled) to turn on backlighting?

Thanks for your prompt reply!
NCK states that it is based on LDS 183 controller (Philips PCF8833 compatible)?
As far as I understand, sparkfun shield is based on either Philips PCF8833 or Epson S1D15G10. So I guessed it should be possible to adapt this library for this shield. Could you comment on the hardware differences that prevent from doing it?
Basically, the code in this library is very clear and flexible, while sparkfun shield is much nicer? Sounds really tempting to merge both :)

Do you know any attempt to adapt this library for this shield?

I did not manage to figure out whether the controller of the nck board is the same or not?
Thank you in advance for your help!

I bought this shield awhile ago but still cannot figure it out the errors i get are

In function 'LCDClear':
error: 'PASETP' undeclared (first use in this function) In function 'LCDSetPixel':

this is from LCD_driver.c

I have added to Marks code and wrote a manual for it.

When using this on the Arduino Duemilanove (328P), do you need to populate (surface mount) the resistors R5, R7, R9 and R11 on this shield?
Looking at the schematic, do these serve as a voltage dividers if these digital signal lines are at TTL levels (+5V, 0V) from devices such as the Duemilanove?

I just got this shield. I'm using a Japanino (which is the Duemilanove, released by the Japanese kit maker Gakken for their Otona no Kagaku (Adult Science) line). I tried using Mark's "Example Arduino code". Initially, I got "program too big" errors, so I stripped out the Mandelbrot and raw RGB bitmap code. Now, Mark's sketch loads and runs, but the SparkFun logo is "noisy". There's semi-random pixels turned on in a line just above and below "SparkFun". Also, I tried changing the logo data just to see what would happen and nothing changed on the screen. My first question is - "do I need to change something in the sketch to make the image cleaner on the Duemilanove? Is the code defaulted to Mega settings that I need to override?" Thanks.

I created an Anlog Clock demo using Mark's example code and graphics primitives from Jim Lynch's tutorial. Youtube demo and source at:

What is the purpose of R13 on the schematic? It is connected between 5V and the VCC pin for the backlight chip? I don't see the equivalent part on the Nokia breakout bd LCD-08600 or Nokia Olimex bd LCD-08683. My backlight does not work on this board.

The Color LCD Shield works with the Arduino Mega?

I solved the previous part!
However, now how do I edit what is shown on the screen?
Sorry I'm new working with Color LCD.......

I currently use a 4D systems serial 128^2 lcd. this will make a few projects much easier
