Procesor Atmega328 TQFP32 z zewnętrznym kwarcem 16M i kondensatorami 22pF do GND, wyświetlacz sterowany po I2C, linie SDA (PC4) i SCL (PC5) podciągnięte rezystorami 4,7k do VCC (5V z programatora ATB USBasp)
Bibliotekę pisałem od zera na bieżąco z wideo-poradników Pana Mirka. Podczas rysowania linii, czy wyświetlania bitmapy z pamięci ram wygenerowanej przez program PixelFactory nie ma żadnego problemu, wszystko działa tak jak w poradnikach, do momentu odczytu bitmapy z pamięci flash. Tu niestety poległem.

Znalazłem problem:
[syntax=c]if(pgm_read_byte(bitmap + j * byteWidth + 1 / 8) & (128 >> (1 & 7)))[/syntax]
a powinno być:

Chyba muszę zakupić większy monitor
