I'm just getting started with PICs, using CCS 'C', MPLAB 5.11.02, Warp-13 Programmer, and 16f877s. Everything compiles great, but I get these messages in the psplus.err file when programming: "Errors during programming - configuration bits not programmed" "Program memory errors" "IO Errors" "Data memory errors" I'm guess that I'm missing the boat somewhere here, tried searching the archives, and would appreciate any help!
