STM32L4R9 DSI with ST7797

[MSeme.1]

Hi,

I need some initialization code for STM32L4R9 to drive a DSI display (1.2 rounded) 1 line. I cannot find any reference online on how to drive this kind of display. I also have initialization DSI frame from display manufacturer but I cannot make DSI work.

If I measure with oscilloscope pins CLK_P and CLK_N, the lines are fixed to HIGH. So I think DSI is not working at all.

Is there available a sample working project that uses pins 75 (Data 0)-76 (Data0) -78(clock)-79(clock)?

Thanks,

Marco.

You write nothink about your code, then two ways:

simpler try TouchGFX example project for L4R9 and correct display set

second clean new project in IDE MX and setup right all peripherals.

LTDC DSI ...
