Waveshare 4.3 inch ESP32 with RPI_DPI_RGB driver no display

Ok, I found an example on this thread from @Jon_2232 :

I couldn’t get it to compile initially. The item that seem to give a display was:

psram:
  mode: octal
  speed: 80MHz

But I had a lot of corruption and the synch didnt seem to be quite right. I think the corruption was probably due to where ever memory was being used wasnt a great place.

I used my timing settings and then folded in Jon’s code and got it to compile and it is displaying his clock demo.

This is what my code looks like now:

    then:

          id: minute_hand

            return id(time_comp).now().minute;
      - lvgl.indicator.update:

          value: !lambda |-
            auto now = id(time_comp).now();
            return std::fmod(now.hour, 12) * 60 + now.minute;

It’s basically Jon’s code, I dont know if I return the timings to his it would be any different. Anyhow, I consider this solved.
