regards,
 

i suggest you to make pic16pro programmer from www.picallw.com there is also programmer software...it uses external supply for programming..easy to construct also..i have used it without problems..

There is not PCB. so U can use my pcb driving
glenjoy pcb size is real. Check your printing setup. Dont use "shrink" and auto sizing
 
Salam,

I think the bugs in icprog 1.05C were solved in the new icprog 1.05D now everything is going fine

Hope that helps

Using the same circuit and having the same problem
using ICprogm 1.5a
error after check "verify failed at 0000h"
my hardware check:
mclr : 15v
vcc,clk : 2.5v
Please someone help its urgent.

Thank you.
 

please someone reply...
what should be done to get the voltage at other terminal to 5v...
Please help very urgent stucked at this point.
 

Bought a new PIC programmer ICSP and found what I was doing wrong..
It was just one pin , in JDM programmer the 6th pin have to be connected to PGM(pin 36 in pic16f877a) then the error will be resolved .
And verify checks if the buffer content and pic content match or not .
Hope that will help.
regards
