Hi! I built myself an ICD module. I programmed 16f876 with mpl876.hex and plugged it into module. When I applied power, LED started to blink. MPLAB gives me warning, that it cannot establish communication. Questions: do I also have to connect application circuit in order for ICD module to communicate with MPLAB? Is it normal that I cannot verify mpl876.hex code written to 876? Thanks, Samo -- http://www.piclist.com hint: PICList Posts must start with ONE topic: [PIC]:,[SX]:,[AVR]: ->uP ONLY!
