Clear TFT Display

by ddesousa on Sun Nov 12, 2017 11:19 pm

Hi there,

I am using the 1.44 Inch TFT display from Adafruit and I was wondering if there was any way to clear a display without using the fillScreen method?

Thanks.

I think that's it for the GFX library:

You might be able to use something from the lower level ST7735 library:

But why do you have an issue using fillScreen?

That function is too slow. I need to rapidly update the screen.

Try taking a look at how this is done in this project:

There's a lot to it, but it does show how it's at least possible.
