T-Display S3 Support?

[MaxSMoke777]

Any thought about adding T-Display S3 support? If you've never seen one of these, here's a sample:

It seems to be very different from other ESP32 chips. It runs parallel graphics on a gorgeous 170x320 display, so I'd love to use your code with it.

It is already supported: https://youtu.be/kpRC64QNQAo

Please find more details in PDqgraphicstest example

You said PDQgraphicstest ok, right? And the GIF example not yet have handle TFT_PWD code, so I ask you copy related code in PDQ main() to GIF example.

[MaxSMoke777]

Yes, I used that code. I could not get it to work. Have you tried yourself?

Could you please show the code you used? I don't see what I'm missing. Or just update the examples in your GitHub? That would help everyone. Thanks!

[moononournation]

I know many people mixed up TFT_BL and GFX_BL, I will improve it soon.

[moononournation]

Please get update to check is it better now.

Success! Amazing as always! I tell everybody I can about your library. Thank you!

[MaxSMoke777]

I made a few YouTube shorts to show off the library, and linked them all back to your page. Here's my favorite...

I've been using Arduino_GFX with a T-Display S3 and it works really well.

I'm using the canvas object as a frambuffer which I "flush()" to the display once per frame redraw. I achieve approximately 26FPS, which is pretty good but it would be nice to have it a bit faster, and seems pushing the data to the ST7789 is the bottleneck (increasing the scene complexity doesn't slow the refresh significantly).

My question is how to determine the speed of the 8bit Parallel bus, and can it be increased?

-edit- I have played with the begin() function and managed to get the display functional up to a speed of 30800000, after which there is graphical corruption or just a blank display.

Try gfx->begin(40000000);, it should work with ST7789.

Ok so 40000000 didn't work (just a blank screen), but 39500000 works fine, with only a slight appreciable increase in speed over the previous bus speed (my guess is we are hitting the limit of the psram where the canvas framebuffer is stored.
