LCD tests with ek79007:
- draw 60x60px squares, random position, random color, clear screen every 1s
- square pixel are filled every frame, which is array of 3600 pixels
-- with PSRAM 200MHz, standard setup

Code: Select all

- draw 160x160px squares, random position, single color, clear screen every 1s
-- square pixels filled beforehand, no need to do it per frame (its like using bitmaps)
