NHD-1.5-128128UGC3 + Beaglebone Black

parsec

I'm about to wire up my newly acquired NHD-1.5-128128UGC3 to a Beaglebone Black using 3 or 4-wire serial. Wondering if anyone can point me to any C/C++ code that demonstrates basic initialization and communications under Debian, or any Linux distro for that matter? Or any C/C++ code that could easily be ported to compile under gcc?

Googled a lot on this and having a hard time finding good tutorials. I want to learn and know what I am doing, in what order things have to be done to make it work properly, not just copy-pasting stuff. Found some Arduino code on this website but tbh the code structure and commenting leaves a lot to be desired.

Thanks!

    Hi Parsec!

    I highly recommend you check out this link

    Please note the following write up uses the SEPS525 controller (same as our 1.69" Color OLED: NHD-1.69-160128UGC3). You will need to modify the initialization sequence and other various parameters if you would like to use NHD-1.5-128128UGC3.

    Hope this helps!

    Hi Paul_B,

    Thanks, definitely a good starting point! I coincidentally discovered BBB iolib a few hours after posting my question here but wasn't sure if it was usable in this context.

    I see in the comments section some guy Paul with a Newhaven display being addressed by the author. Was that perhaps you?   Did you have any success in getting it to work in the end?

    Any idea where I can find more information about this?

    Hi Parsec!

    A great place to start is by viewing our example Arduino code:

    https://github.com/NewhavenDisplay/NHD-1.5-128128UGC3_Example/blob/master/examples/test/test.ino

    You will need to modify the initialization sequence in the BBB iolib to match the NHD-1.5-128128UGC3 parameters.

    Be sure to have the NHD-1.5-128128UGC3 example code open and scroll down until you see the "Initialization Start", see lines 1055 - 1106 and modify the appropriate files in iolib  

    Hope this helps!
