I would suggest formatting the icon as a XBM and the using drawXBitmap, no need to decode the bits yourself:

FOexample

#include "somexbm.h" ... M5.Display.drawXBitmap(0, 0, xbm_bits, xbm_width, xbm_height, TFT_BLACK);

The .h file will have

#define xbm_width 540 #define xbm_height 960 static unsigned char xbm_bits[] = { 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, etc

You can easily produce an XBM file with GIMP or some other program. I don't remember the format, but I thiink the file is just a bitwise stream of pixels values.

@paulpattyn Uh, how about use Google : https://www.instructables.com/Post-to-Google-Docs-with-Arduino/
