3 years ago What compiler ide are you using? I see Moc OS, and then a hundred warnings about unused variables, and complaints about "int" vs "long int". Not clear which is the actual problem, but it is much more aggressive error checking a Arduino IDE. Are some of these lines in red? Or can you turn off the relentless error checking?

I'm trying to compile v09 with and I'm getting the following errors:
