Hi, can anyone tell which of all the displays works normally on the FC8?
We wrote a small program to test 2 displays.
GLCD KS0108 and ST7920 parallel.
The first does not start, the second starts but works very slowly.
Both simulations work without problems, but they don't work on a circuit board ...
