hello list! i have today got problems with my icd 1 with a 16LF876 chip... i used this device a couple times for about 3 years. i have first used the orginal firmware with mplab 5.20 and the went to c coding with the ccs pch pcw compiler with this software came a "icd-s" firmware and a seperate software. called "Icd.exe". this tool allows me to switch the firmware in the icd chip to 18f oder 16f devices. last pic i was programming with the icsp was a 16f877(a) and today i wanted to programm a pic18f6720 and made the same thing i ever do. .- switch the firmware to be able to programm the 18er series . then it happend. the device hang up and then i think did the mistake.. after the device made the firmware update the software- device sayed "could not find icd check power and cable" ok.- i switched of the icd and powerd on again. but i thing i would never see this again. "Could not connect. No response from ICD, check connection and power to icd" does anybody had this problem too? how could i solve it? thank you tobi -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
