I am trying to program a PIC16F84A using the Enhanced JDM Programmer's ICSP connector. It keeps failing with "Verify failed at address 0000h!".
If I put the chip on the zif socket then it works.
The voltage on Vpp is about 13V while programming. Vcc is about 4.6V
On the 16F84A I connected:
16FF84 Pin ------------ ICSP Pin
12 -------------------- Clk 13 -------------------- Data 4 -------------------- Vpp 14 -------------------- Vcc 5 -------------------- Gnd
Does anyone here have experience with this?
Thanks |
