I have written a program that runs on a PICMASTER for a 16c74. It works fine running in the PICMASTER, but I burned an EPROM 16c74 and the program no longer works. Nothing shows up on the LCD display. There is an LED that should flash. Its flashing but the duty cycle is not right and the buttons do not respond properly. It sounds like program is going off to la-la land. I have some long calls, but they work fine in the PICMASTER and the WDT is not used (turned off.) Any ideas on what the problem could be? TIA! ----------------------------------------- Mike Montalvo G-FORCE Motorsports http://www.g-forcemotorsports.com 516-794-0858
