I need to put a certain amount of values over the serial port. So I have created an array that according to the Serial.write documentation i can send in one line of code. But I get errors.
The documentation (again) is not comprehensive: Serial.write() - Arduino Reference
So buf should be the array and len is?
Produces an error: no matching function for call to 'write(volatile char , int)'
At this point i cannot continue.
