jdm programmer
Hi,
I am using JDM programmer to program the PIC16f877. My connection is
5V power
VDD and VSS from external power supply
MCLR------- ----TxD
DATA(RB7)-----DTR + CTS
CLK(RB6)------- RTS
RB3-----GND
I have come across a strange problem.
winpic800 is not detecting my pic16f877a chip but Ic-Prog is programming as well.
if i place the positive lead of Multimeter to the MCLR pin winpic800 is detecting my chip.
So my questions is what is happening when i place the multimeter lead on MCLR pin of PIC16f877a and how the winpic800 is detecting that ic.
how to rectify it.
Regards,
M.sukumar
