    Hey JackPhan,
    Here is header file and source file for the SSD1551, with the code being based on an ARM7 (lpc 2148), so the low level functions (send command, send data) might need to be modified. It uses a frame buffer as well, so if you do not have enough memory you’ll have to edit that, but it has text writing, line,circle, and rectangle drawing, plus some pong action as well

    This display is completely pin compatible with the original (that used the ssd1339 driver), however it does not support 8 bit (256 color) mode, and therefore must have 2 bytes of color data sent over its 8 bit interface. If possible, get the version of this display that has the full 16/18 bit interface as the lack of 256 color mode causes a drop in performance (as compared to the one with ssd1339) that you cannot help. That being said, I have used this display with the arm7 (2148) and am happy with it. If anyone wants, I can post a link to my driver code which has many different drawing functions and a few different text sizes.

    I just want to point out that you should be careful with this thing. I have had it for a little over a week and after heavy use (constantly reprogramming and testing it) the switch broke and corrupted my memory card (easy fix, but the switch is annoying). I would just recommend adding another port for that pin so that if someone wanted to hook up their own switch (say in the event that the one on the board breaks..) they can fairly easily. Other than that, it’s a good product.

    Actually, nevermind, After much more searching through the forums, I found that it was the formatting of the card. I’m still puzzling out exactly how to format the card (I just found another uSD laying around and it worked, but when i format the older cards using FAT and between default,16 KB,32 KB,and 64 KB allocation units they do not work).

    So I have one (two actually) of your dataloggerv2 boards and somehow messed up the bootloader when programming using the FW.SFE file on the SD card. (I.e. the device still shows up as a MSD but does not actually self program after disconnecting and power-cycling) and when using the serial programmer I am able to program the bootloader source onto the board again but it still has that same problem, do you guys (anyone, but mainly SF) have any idea why this might be the case and any ways to fix it?

    It would be great if you guys added this part to the SF Eagle Library :D

    Any idea when these might be back in stock? Or does anybody know a place where I can get capacitive multitouch screens? I have been working with resistive screens for a while, and would like to write a small OS for a multitouch screen. :)

  • Product LCD-08858 | about 5 years ago

    Hey, I was just wondering how I might be able to fix the bootloader on my lpc2378 board I got from here. I have the jumper set on the J1 connector to enter ISP programming mode, and have hit the reset button and tried communicating through Flash magic to the board to upload code. However, whenever the board is connected to my computer, my computer tells me my device has malfunctioned or is not recognized. So I cannot set it to a COM port and can’t use Flash magic. The board works other than that, I just can’t download code to it at all :( Any help? :D

  • Product WRL-08497 | about 5 years ago

    Hey everyone! Does anybody know how to access the D+ and D- pins on the bluetooth module (pins 17 and 18)? I am wanting to use them for my data/command transfer over bluetooth as well as to the bluetooth module but am slightly new at this and cannot seem to find documentation on it (I can’t even find the actual datasheet on the roving networks site, when I go to the RN-41 webpage they have it gives me the RN-134 datasheet which is a wifi module). Any help would be greatly appreciated!
    (p.s. I am using it to program/transfer data to/from the AT90USB and am wondering if it is possible to just hook it up to the D+ and D- lines of the AT90USB and if it will just transfer the data from bluetooth to those lines and vice/versa)
    Thanks!

No public wish lists :(
