The datasheet for this controller board can be found here:
I'm having trouble getting the back light to turn on. After looking more carefully at the board, pin 3 (B/L Enable) on the 34-pin MPU side isn't connected to pin 2 on the 40-pin LCD side (there isn't any pathway leading out from pin 3). I'm pretty new to doing embedded programming and stuff, and I was wondering how I can turn on the back light for the display? Is it possible using this controller board? The display I'm using is the NHD-5.0-800480TF-ATXL#-CTP if that info is needed.
Also, according to this datasheet here for the LCD, https://newhavendisplay.com/content/specs/NHD-5.0-800480TF-ATXL-CTP.pdf, it says that the back light requires 60 mA @ 19.2 V, but on the other one for the controller board, it says 20 mA @ 23.1 V instead. Does this means that either or can be used, or....what? Sorry I'm a little confused at this part.
