So I managed to rotate the screen 180 degrees but getting the text to read left to right is giving me a headache. Text displaying backwards now from right to left mirrored but bitmaps etc display correctly. Looking at other arduino/esp libraries i followed the same init sequence but no luck: sendcommand(0xA0 | 0x1); //SEGREMAP //Rotate screen 180 deg //sendcommand(0xA0); sendcommand(0xC8); //COMSCANDEC Rotate screen 180 Deg //sendcommand(0xC0); sendcommand(0xDA); //0xDA sendcommand(0x12); //COMSCANDEC Anyone familiar with the onion oled library that can point me in the right direction?
