Thanks
Declare your variable as usual in whichever .c file, and then add an extern in the other .c file where you want to access the variable. Example:

Code:
user_SerialDrv.c:55: unsigned char aBreakerWasTripped; // Creates the variable.


user_routines.c:22: extern unsigned char aBreakerWasTripped; // Tells the compiler the variable exists in another module.
