I registered here for something very similar to this.
I'm using "TFT_eSPI.h" to do a simple clock demo and if I set the font color with:
Code: Select all
tft.setTextColor(TFT_BLUE, TFT_BLACK);
(blue is font, black is background of the font) it writes and updates the TFT ok given that my background is also black.
However if I want to display just the font color without its associated background with
every time the hour or minute changes it'll overwrite on top of the previous number and become a jumbled mess.
I'd much rather have the font be background independent and not have to have a matching background canvas of a solid color to rid of the surrounding blocks around the letters and numbers.
Wonder if there is something similar to a horizontal or vertical blank similar to analog TVs that I'm missing?
