Problem in interfacing NHD-3.12-25664UCW2 device with STM32F767Z

Hi,

This is Sivaram and I am working with NHD-3.12-25664UCW2, at present. Please go through the following points,

1. For product development purposes, first, we connected NHD-3.12-25664UCW2 with the STM32F767ZI EVK board in 6800 modes and were able to glow the target pixels upon the screen.
2. After gaining confidence in interfacing OLED with the EVK board, we considered the same STM32F667ZI processor in our custom board design.
3. Unfortunately, the OLED didn’t turn on after interfacing with the processor in the custom board. Even though we didn’t change anything much in the code.
4. Can anyone suggest a solution for the present situation?

Thanks in advance

  It sounds like there might be a hardware issue with your custom board. Double-check the power supply and connections, especially the data lines and control signals. Also, ensure that the initialization sequence in your code matches the requirements of the NHD-3.12-25664UCW2 display. Sometimes, even small differences in hardware can require changes in the initialization code. Dog blog
