ESP8266 Community Forum

I have 2.2 TFT display connected to hardware SPI and using UCGlib. It is stable, however screen updates are too slow - for example when changing text color I can see each letter painted with new color, from left to right. Is this a library issue or this is inherent to lua implementation?

Here's an example of Arduino running on ESP8266 driving the same display and doing so much, much quicker:

Can you please post your Lua code here? Maybe there are ways to tweak the performance.

It is also slow on a refresh using the IDE with C code. I did raise this sometime ago with the guy who done the porting of this library. I have gone back to Adafruit and GFX combination simply for this reason.

Good luck
