Hello everyone,
I'm working on using the LCD-TFT screen of the F769I-DISCO board but working without HAL/LL libraries. I managed to turn on the screen and display the bars of the DSI pattern-generator, however the screen slowly turn black, starting from the corners as you can see in the attached picture.
To get the screen to become bright again, I need to power off the board for few minutes and power it on again.
The LCD is fine as in it (still) works perfectly fine with the ST demo for F7 discovery.
I would suspect an issue in the screen configuration (maybe some voltages are wrong) but I got all parameters from ST BSP files from the STM32CubeF7 software package.
Would someone know why a LCD screen would do that (for me to go look further into the driver documentation) or had this issue and fixed it somehow ?
Best regards,
Julien FAUCHER
