TFT examples ie ST7735 IL*

[tablatronix]

I am trying to get st7735 example ported, using the ada gfx library the fillscreen and spi draw for clear takes a long time and it flickers.

Might try pdc lib, tft_espi would require some library rewrites, pdc should be gfx compatible with spi optimizations, can try that.

Maybe a wrapper for tft_espi class to make it have a gfx object container shrug not sure how

If anyone has any suggestions for optimizing gfx spitft esp8266 routine or know of a fork let me know thanks.

Oh forgot the obvious, to probably implement this we would need to minimize the redraws to the pixels that changes only, double buffering is probably not an option as the memory and speed would be just as bad, so modifying the lib to just check last positions or the smallest rect tracking per piece and write bgcolor to it.

Probably too much work, but feel free to comment if you want a color tft , there might already be another library to do that, or if you have any ideas..

I will try a few more tfts in a bit and see if any support this better in the driver or ic.

Hi @tablatronix @witnessmenow ,

This library is awesome!

did anyone write a wrapper for TFT_eSPI? I just got an ILI9488 display and have the TFT_eSPI examples working fine, but can’t pass the TFT_eSPI object to the Tetris animation object (I can share the error later if that helps, on my phone right now).

Also the ezTime examples seem to be crashing my esp32 board, but I can figure that out separately.

Cheers,

Pete
