I built my first programmer, and I went to test it with the software supplied on the site that i got the schematic from, however it is refusing to program my chip (Pic 16F88).
I had a look at the pin levels and found that MCLR is always sitting at +13V even when the program says it has been disabled, could this be the cause of the programming failure?
The procedure Im using is Start software, place PIC in socket, attach programmer to computer, power up programmer from an 18V power source, Erase All, Program all, Verify (Verify fails at 0000h, Read All (Returns hex data as 3FFF), Check Blank (Returns the PIC is blank).
The programmer I am using comes from www.oshonsoft.com/picprog.html
Any suggestions?
