Re: ESP32-S3 RGB LCD maximum throughput
There's no problem with the LCD display. And the PSRAM is actually working at almost 80 MB/s. In fact, yesterday I was able to drive the display with a pixel clock of 40 MHz (almost 80 MB/s) by displaying a static image e not using the PSRAM for doing anything else in the application code. This mean...

ESP32-S3 RGB LCD maximum throughput
Hi, I'm currently developing a custom board with an ESP32-S3-WROOM-1-N8R8 driving a 800x480 5" LCD display with a 16 bit RGB interface. The problem is, the display works correctly only with a pixel clock up to ~14 Mhz. Increasing the speed leads to visualization problems (the image on the screen shi...
