any way you could help with setting up code for this display using a esp32s3

cant seem to get the display class working in arduino isp

I also encounter similar screen while mislead a GC9503V as ST7701V, try get update and use the new class Arduino_GC9503V_RGBPanel

still no change on the display. Every uplod of hello world does nothing. What do I need to change in the src files to get this to work? I used provided esp32rgbpanel bus class and arduino st7701 rgb panel display class. attached is the start up code the vendor sent to me. I appened my display class .cpp file.

I am using esp32-s3-devkitM-1

can you take a photo of your connection?

this is how I have it wired, hard to get photos that easily show but I have triple checked connections including continuity.

can you follow the default pin connection first?

I have it pinned corisponding to the bus class listed for esp32s3 and st7701. I made that pdf to keep track of all my connections but used this to make it.

Thanks for you code provided, Please get update and check the new code is it work:

Arduino_ST7701_RGBPanel *gfx = new Arduino_ST7701_RGBPanel(
  bus, 33 /* RST */, 0 /* rotation */,
  false /* IPS */, 480 /* width */, 480 /* height */,
  st7701_type3_init_operations, sizeof(st7701_type3_init_operations),
  true /* BGR */);

RGB display requires allocation a full framebuffer. The internal memory will limit the resolution.

nrjn Aug 31, 2022

ok thank you

jotisk Nov 23, 2022

Hello, is possible to reduce color bits to allow 480x480px framebuffer on S3 without PSRAM? like RGB454 or similar scheme?

moononournation Nov 23, 2022

RGB454 cannot help reduce the size. And it is the native driver from arduino-esp32, I cannot change how it implement.

I was able to got ST701 working on my custom board but I have problems with some glitches when repeatedly writing to display. GIF animation works first few frames and then looks like broken hsync. after while it is correct again. Same with hello world example, first few texts are correct then is image distorted for a while and sometimes fixes itself.
Any idea where to start?

Another question, is possible to speed up gif framebuffer write? with earth gif animation I can see how is frame writing to framebuffer on display (lines are flickering like on your video) or it is limitation of psram performance?

Thank you very much for support.

It have a big change on RGBPanel and release soon. You may get update and follow the latest PDQGraphicstest.ino to test again.

perfect, thank you for info, I will watch for update.

May I ask you for hint how to init RGB panel with new library 1.3.1?
old code

);

/* More display class: https://github.com/moononournation/Arduino_GFX/wiki/Display-Class */

true / BGR */,24,6,18,16,4,10);`

I tried new one, but data are somehow not sent:
