Hello Tomasz,
There is no way supported by the "k" software version, that the pixels
of the display can be shown inverted.
Probably you can try to find a better contrast value in the menu (Contrast).
But you should know, that the contrast value is decreased by a short key press
and increased by a longer (>0.5 s) key press. A very long key press will save the value.
If the contrast value is changed to a wrong value, the content of the display is unvisible!
Sometimes the content is visible with a look from the side to the display.
Otherwise you can try to press the key many times with short presses to get a visible
value. If a wrong value is saved by the very long key press, there is no way to read the
menu again. You must reprogram the ATmega to reset the contrast value to the default value.
You can also change the start value in the Makefile (CFLAGS += -DVOLUME_VALUE=48)
and recompile the software.
Best regards,
Karl-Heinz
