I have tried it with Include "modedefs.bas" and without. The code is not very long. What I need is for someone to look at the 2 files and see if they can tell why it won't work on the PIC. I have both the PIC and the Stamp and FT639 and Bluetooth module on breadboard. When I hook the 2 serial lines to the Stamp I can control the servos. When I remove the two serial lins and connect them to the PIC. it won't work. All the pin configuration is documented in the 2 files. lt appears to be a serial problem. When I power up the circuit it should automatically center both servos. It does with the Stamp but not with the PIC. Hope this helps.
