Clear TFT Display

[ADAD_d]

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.

I have the same issue. Did you find a solution ?

Or does anyone knows is there a something like like tft.clear(); ?

I found a solution here ; https://github.com/adafruit/Adafruit-GF ... /issues/16

Simply write tft.setTextColor(ST7735_RED, ST7735_BLACK); before the tft.print.

Code: Select all

 tft.setTextColor(ST7735_RED, ST7735_BLACK);
 tft.setTextSize(2);
 tft.setCursor(10,50);
 tft.print(t);
