Hi Julian,
I am having problems with the print and println statements with the Mega1280 board. When I print either from within a taskloop or in a function called from loop, the board hangs. I have tried delays, etc and made the change in main.cxx, but I only get the first line printed which is "Pump Pressure = 12.5". As you can see from the commented code below, I have tried lots of variations without success. Any ideas?
P.S. how is the update coming?
Cheers, Jim
