ESP32 and ILI9488

[Stke7]

I've configured and tested LovyanGFX with the example codes and it displays properly. No issues on the config part but i cant get the display to work with the ScreenShotReceiver. it shows up like this on the screen.

Sorry, ScreenShotReceiver is limited to 16-bit color mode to gain frame rate Since the ILI9488 must be sent in 24-bit color over an SPI connection, the The ScreenShotReceiver cannot be displayed properly.

I created an unstable branch with an additional 24-bit mode.
Probably works fine with ILI9488. Please give it a try.

Ok i've just tried the unstable branch and it's working! Thank you so very much! I've done some benchmarking for you @60% quality and 40MHz spi write.
7fps at 480x320 no DMA,11fps with DMA
14fps at 320x240 no DMA, 20fps with DMA
50-52fps at 160x120 no DMA, 57-62 with DMA

Congratulations and thank you !!
You've probably set "freq_write=40000000" .
If you can run at the SPI setting of 80000000 you will get double the speed.
I don't know if the ILI9488 will be able to keep up with that speed, and the limit value will vary depending on the wiring conditions.
Try it out if you're interested.

I tried it, does not work at 80Mhz. The picture is distorted. Thanks for your Help!
