Programing PIC microcontrolletr using other PIC MCU

[ismu]

i want to flash PIC microcontroller using other PIC MCU , how can it possible? i think we can go through ICSP protocol , but no were mentioned about the command code

Hi,

There are many Pic based Pic programmers out there, the most popular being Microchips own Pickit2 or Pickit3 programmers.

If you search this form for 'pickit2 ' there are many similar plans for building a simple or full diy Pk2 clone which uses a 18F2550 chip with the free firmware from Microchip.

They are capable of stand alone or ICSP programming, via Microchips MPLAB IDE or its own stand alone program V2.61

I have a firmware for PIC USB Programmer and also the Circuit which uses 18F2550. I will post it in a day or two. I have to find it. It is somewhere in my old HDD.

ICSP programming is described in Microchip documents, e.g. DS39622 "PIC18F2XXX/4XXX FAMILY Flash Microcontroller Programming Specification".

Hi Mr. Wp100

that i know , but i want to do programing without using PC .

i want to do programing without using PC .

how is that possible bro ???? !!!!! how to load .hex file without any pc ?

Hi,

how is that possible bro ???? !!!!! how to load .hex file without any pc ?

I think he means a standalone programmer with its own memory (flash?)

In lab you can push the hexfile onto the programmer.
In the field you can use the programmer without PC. Good idea.

Hi Mr. Wp100

Low cost programmers like Microchips Pickit2 and Pickit3 have a function called ' Programmer To Go'

You download the .hex file in to the Pickit from the PC and it is retained in its memory even when disconnected from the PC.

You can then take it to remote devices and program them from just the Pickit.

If you literally want to program another Pic from a Pic that is possible - you serially transmit the program code to the target chip which has a bootloader or similar existing program routine to take the new code into program memory .
