Well, ALMOST all is working.
I now manage to edit, compile and upload the sample firmware, using something like
for(int i=0;i<4;i++)
{
RainbowCMD[4]=i;
DispshowPicture();
delay(1000);
}Images do change, but the “top line” (towards RESET) always has the blue LED part on.
(Already seen on the “default pattern”, btw.)
Known problem? Software issue or does it look like a hardware thingie?
Best,
Jens
