HI guys...
I am trying to load a bitmap image on Weact 1.54" epaper display.
I found a sample for text..but I don't find any for bitmap
So I tryed to edit this: but I receive this error
Compilation error: no matching function for call to 'drawGrayscaleBitmap(const unsigned char [5000], int, int, int16_t, int16_t, int)'
Where can I find a code sample?
