OpenCM 9.04 with ILI9341 using Arduino SPI

senmot · December 22, 2022, 5:41pm

Hi everyone,
i’m currently using OpenCM9.04(SPI 2) to control an ILI934-Drive tft Display based on the Arduino SPI Lib form Robotis [OpenCM9.04/SPI.cpp at master · ROBOTIS-GIT/OpenCM9.04 · GitHub]

I have tried to use *void SPIClass::transferFast(void buf, size_t count); in the Lib to increase the refresh time of my Display, but it didn’t work at all. Does anyone know how to use this function correctly?
I would be grateful if you could provide me some information. Thanks in advance.

Here is part of my code:

Dev_config.h

Dev_config.cpp
Dev_config2

LCD_Driver.cpp
