    Works great , even with my mac . Decodes serial & other signals without trouble . Highly recommended !

  • Product BOB-09816 | about 7 months ago

    I suggest You use MAX6675 ( up to 1020'c ) or MAX6674 ( up to 125'c or so … )

    Mail me and i will reply with some pictures of my preliminary layout …

  • Product LCD-11788 | last year

    I bought this display for a HUD project . But as cool as the display is , it is not bright enough to be seen clearly in daylight . It also dims very slightly but visibly to the end opposite the flat cable … ( if You have big fonts displayed the digits dim a bit to the end of the display ) Anyway i will install it shortly to my car and i will post back more user experiences .

  • Product SEN-11792 | last year

    I had problems with the previous version C2 ( could also be user related :) but this C3 works great . The speed is around 550ms , quite fast . Works for me !

    Worked well while it worked . I connected the reader by usb and run the demo software . I enrolled a few fingers and it worked surprisingly well , after a while of fiddling with the unit i closed the usb connection and unplugged the unit . I thought of many places where i could put a fingerprint reader , i decided to install this one in my car . Today i tried the demo software again , when i open the connection it displays serial and firmware versions , displays enroll count , deletes fingerprints , but does not enroll or read fingerprints any more . When i click enroll the blue led flashes briefly in the reader and the software displays Device error! , if i click verify the blue led comes on but does not recognize a finger and after awhile displays time out … I may buy another but it would be nice to know why this one died … Maybe the writer of the demo software has not read the special note ?

    Well i may have been a bit harsh . Usually change and development is good , but i would have welcomed if the old protocol would have worked also with the new one . I got frustrated because i had a simple project that should not taken more than a few hours to build … copying bits and peaces from old programs to the new , but when i discovered the old commands would not work with my new display batch , i did not have time to research and implement the new protocol … Just later i found that i could use the V3 workshop to update the G2 displays to the old serial protocol . In my opinion , i would like a display that is easy to use , preferably ascii commands ( this is just my preference ) , has some built in fonts ( adding your own is great but i would rather buy a display with some pre installed fonts ) , and has input buffer ( this would be welcome !! ) ( and getting rid of the reset line would be an asset too ! )

    I meant with the bad transmission that my program decided not to wait any longer for the ACK and issue a new command to the display causing it to crash , this is not the displays fault but my programming . ( Reach displays have a 512 byte input buffer , You can send continuous data to the display @19.2kbps with just a TX line without any lost commands . ( of course You should read the ACK , but not necessary with a big input buffer ))

    I have a 1.7" OLED display housed in a water tight enclosure in my sauna installed at a height of 2m ( temp about 70-90'c ) , it has performed very well in my abuse test for 3 years now . Now that i know it can withstand high temperatures i will install a lot more to my friends saunas .

    I did not realize you could write your own protocol , all i see and hear is the serial protocol . Do people use the other modes ? Standalone anyone ??

    Not that i want to speak bad about 4D systems , but the language this serial display uses is horrible compared to Reach Tech displays . I have used many 4D systems OLED displays and i like the displays but the protocol is awful , the old protocol was a bit simpler but the new “Serial” is more clumsy than the old one , this applies to the OLED displays , these new displays come only in “Serial” = new protocol . It does not survive a few bad transmission but crashes the display , never happened with Reach Tech displays , the price is a bit higher but so is the quality of the firmware .

    Nice project , but the leds are poor quality . Mine’s been running nonstop a bit over 2 years now , and now there are 5 blue leds that are broken . The good news is that the first blue died a short while ago , but the rest are following fast . I have not measured the current fed to the blue’s but still i think it’s just that the leds quality is not good .

  • Product LCD-11000 | about a year ago

    Is the display software still slow ? I have an application that updates 10-20 values with a 2Hz update rate . How big is the input buffer ? I built two projects with ezLCD-001 , and the lcd’s were horrible , the software on the other hand is far better than current 4D systems displays . ( You have to love the look of the OLED displays but using them is awful , they are incredibly slow and don’t have an input buffer ) There are no better serial TFT displays than Reach Tech displays but unfortunately i need to do a few projects with a minimum budget so i will try this ezLCD … Normally i use solely the Reach Tech displays , they work great , tech support is awesome and the serial language is superior .

No public wish lists :(
