I've been playing with my promate II programmer, and having some problems doing ICSP. I have an adaptor which converts my 15way High density D plug to the 6 way modular, like on the in circuit debugger, and I can then connect the ICD header board using a DIL to 6 way header to my target board, for either in circuit debugging or promate programming. However when I make a direct 15way High density D to 6 pin header lead, the thing reports "Error during programming, Vdd won't rise" Surely this cannot be due to the resistor or the diode or the capacitor on the ICD header board? Anybody got any ideas? Regards, Kevin -- http://www.piclist.com hint: PICList Posts must start with ONE topic: [PIC]:,[SX]:,[AVR]: ->uP ONLY! [EE]:,[OT]: ->Other [BUY]:,[AD]: ->Ads
