I have the STM32 Dev Board, the NUCLEO-H753ZI, and I am programming a Display Module from Newhaven, the NHD-5.0-800480FT-CTXL-CTP. I am using the QSPI communication protocol setup from my STM32 CubeMX to program and setup the appropriate inputs and outputs, along with the clock, in my STM32 CubeIDE (V2.1.1).

The issue that I am running into is that my backlight is not turning on. I have some code that I can share on demand, but any sort of help that I can get would be greatly appreciated! Thank you for your time

Hello @chad.harris,

Well, basics first. Are you supplying the VBL pins (17, 18) with a suitable power source?

Are you writing appropriate values to the backlight signal control registers?

Good Afternoon!

Thank you very much for your prompt response! It turns out, that I was using Clock Mode 3 for my Display, while the FT813 chip that is on the module only supports Clock Mode 0, so that is what was wrong with my setup. Thank you for your help though!
