Still fighting the ICD2 interface..... I built up a 16F877 socket, put on power,gnd and wired up Vpp, B6 and B7 to a header, verified that I have vdd and vss on the right pins, and that the header is connected to the right pins.... I get an error on the Target Vdd and Vpp, for a 5V system its reading 1.87 for Vdd and 6.71 for Vpp. I do have a 10K pup on Vpp as well. Verification of the ICD2 has been done on another one of my dev boards. Seems so simple that it should work. I'm going to change out the resistor pulling up Vpp, since its a 0402 pkg, could be bad (ok...I'll pop one end and check it) and the target Vpp is reading half what it should. Anyone else seen this and want to offer a suggestion? _________________________________________________________________ Click here for a FREE online computer virus scan from McAfee. http://clinic.mcafee.com/clinic/ibuy/campaign.asp?cid=3963 -- http://www.piclist.com#nomail Going offline?
