Hello Everyone !
I need to program PIC18F24J11 ic. so, I have made Picpgm USB programmer and it has been detected by PicPgm.
The Staus Bar Indicates Picpgm USB programmer and USB(FT245B).
But There is "No pic Connected" error. My PIC ic doesn't detected by Picpgm.
I have Checked All ICSP signals. all signals MCLR,PGD,PGC,PGM are working properly.(with Hardware test in Picpgm).
this PIC has normally 3.3v VDD supply. so i have not connected ICSP +5V to VDD.(Left +5V wire open.).
Also this PIC doesn't define PGM pin so i also left it open.
I have used 100 Ohm resistor in series on PGD between Programmer and Microcontroller.22pF capacitors are atteched between PGD and GND, PGC and GND. This is for filtering Purpose.
One thing i should also mention, that i use +3V Button Cell (2032, used in Computer) to provide supply to Microcontroller and i use Laptop for programming.
PicPgm gives error like below :
Pic Unknown ! Programming may fail !
Calibrating delay: 50us delay took 5403us (loop counter=703)
Please give any Suggestions/Help/Comments.
Thank in Advance.
