OK....i added the linker to the project and it ALMOST fixed things. MPLINK 3.60, Linker Copyright (c) 2003 Microchip Technology Inc. Error - could not find definition of symbol 'init_timer1' in file 'C:\A_dev\735\mastri2c.o'. Errors If you look at AN735 code from the mchip site, it has several include files, etc (I wont just include the entire code here) The section of code that has this is in the init.inc file, and includes another call for initializing the ports so I know the code is being included, yet it doesnt seem to find the other piece of code. Kinda strange. EXTERN init_timer1 ; reference linkage for function EXTERN init_ports ; reference linkage for function so init_ports is inside the init.inc file as is init_timer1, yet i get this error. --------------------------------- Do you Yahoo!?
