kD1 · ‎2020-09-19

Hi STM, we are working on DSI of 240x320 with STM3F769NI Micro controller with our own PCB design. Could you please help us in providing any sample code which have worked with 240x320 display.

Get the data sheet for the display, and start with the parameters and expectations then.

Select LTDC and DSI clocks based on requirements established above.

Take the F769I-DISCO LCD code as a model.

Thanks for reply clive. I have generated GFX code with IAR IDE 8.40. Code is not hitting breakpoint at screen1 while running task. I have tested by implementing another task, it is hitting second task. why GUI task is not hitting but reaching to frontedapplicationbase but not hitting screen1viewbase?
