Just recently I have been having a problem trying to program my 17c756 chips. I am using MPLab, PIC Start Plus V1.5 and the Microchip 17c756 ZIF programming addapter. I have had no problem for about 2 months now, that is how long I have been programming the 17c756's for. The problem is I keep getting an error while programming that says, "Cannot receive. Please verify serial and power connections and reset the programmer. [0100,00,DF,E0]." It does not allways happen, about 80% of the time, and I have tested every thing. I tested the serial cable, the power supply. I tried other computers with other OS's and other PIC Starts. Can anyone tell me what this is caused by? -- Roy Souther silicontao_roy@technologist.com ICQ# 1232391 Attachment converted: wonderland:what.zip (pZIP/pZIP) (00007535)
