Hello I found a weird compiler bug.

A file register was dumped with remains from the byte to int automaticconversion.

I needed to add typecasts.

This caused a weird overwrite! I really checked all the wires, but found no error.

 

It's not a bug, it's a feature (landmine). Don't trust the 8 bit compiler to do 8/16/24/32bit auto-conversions. Tell it explicitly every-time and use L after 2 digit constants.

Well worth bookmarking. Thanks

 

I had the opinion the code works, but registers are trashed. Using the typecasts, I can use these other regular variables now.

Because I visualized variables in binary on the LED matrix...I saw the behaviour. This is an idea I had, using the PCBs functionality.
