I am using the following code to read power from A0 analog port of an Arduino UNO. The offset value changes from transmitter to transmitter hardware. So it is calibrated once and store in the eeprom. Pin 3 is used to request for change of offset value, but it is called rarely. The code works, but …

Actually oops here, too. A bool should be a byte which is inherently atomic on the AVR platform. But it should still be volatile. It tells the compiler that the variable is in shared memory, and not a processor register for optimization.

I don't see any loop() or setup().
Did you know that the EEPROM library, can write an 'int' to EEPROM in one call?
