Hi.I started a small project using a custom board with STM32G0B0, SPI flash and 3.5 inch ili9488 LCD, communicating via SPI using the TE pin, without RTOS. Everything loads fine and quite fast, but after 5-40 seconds the uC freezes. Especially when c...

1)The H503 example uses the TE pin and VSYNC/HSYNC. I only use the TE pin. The movie has a second part.3)I only use internal oscillator for test, probably LCD + Debugging via stlink is too much for this uC. 4)Even everything is in internal flash/RAM....

1 )Yes, but for the TE interrupt I use an additional function - vsync partial buffer, so there are some differences in the code. To implement this function, I used a video on the STM channel https://www.youtube.com/watch?v=Ra-83E1heB4&t=7s Without th...

Thanks for answer.1. TE pin - Tearing Effect Interrupt from LCD3. for some reason I can't debug using st-link. It looks like the uC is slowing down dramatically and the TouchGFX gui is not starting. I haven't had this problem using RTOS and LTDC in o...
