Build a programmer by own 100%

[chyelim]

Hi, friend, is anybody willing to share on how to build a programmer in PICs ?

My meaning is like create a own software and hardware for flashing PICs. Totally start from ZERO. Step by step up, bit by bit sending the HEX file to the MCUs.

Thanks !!

Hi
try PicKit2
http://www.microchip.com/pickit2
source code avaliable
I think is a good start point.

hmmm
i wish to make one for 8051

Build either serial or parallel programmers, both a nice and easy...a good start anyhow

hi
see this post
best programmers for pic

Hi, friends, what I mean is to build the programmer by ourselves including the software, firmware and hardware. The purpose is to learn how actually the firmware flash into the MCU. I think there is many hobbyist would like to learn about this. We need the lowest knowledge to build the programmer eg. how to send data bit by bit, byte by byte or packet by packet from computer to the flash programmer. Willem Pro and WinPIC800 is the example. Is anyone here who is expert in this ? after built then can share it open source so that other members or hobbyist will help to upgrade it become more powerful or become multi programmer that means it is not only can program PICs but also other MCUs or EEPROMs. We can call it Sonsivri - Programmer which is open source to all members and hobbyist so that we no need to source so hard for a best programmer since we have the best and expertise here in the forum. What will you think

I'm with you Chyelim, and i think we should start understanding ICSP fonction first

I'm with you Chyelim, and i think we should start understanding ICSP fonction first

I'm too ... but i just newbie. I would like very much to join the group.

[chyelim]

Is anybody here can explain how actually send those bits in the HEX file from the PC to the PIC mcu ?? Can show some examples code so that begineer can get understand easier. From PICKIT2 source code is in C# language but it is too complicated and hard to understand. Can anybody shows some simple code ? maybe we can start to program EEPROM first also can.

[Ahmad_k]

The source code of PICKIT2 is divided into several functions you can see a description about each function in description file delivered with the source code. So we can you these functions

anyone interested to do it for 8051 lets do that......lets make our own firmware , software + hardware for 8051 programmer.
im just fed up with my programmer which is " ez downloader " available on internet.

Almost all new PC dosn't contain a LPT port, so this programmer isn't suitable.

[chyelim]

Hi, guys, I finally found my very first PIC programmer code that had been written 3 years before which only can program PIC16F84 using LPT. Maybe this can be the starting point.

I built this willem  and it's way to expensive and not very user freindly and I had  little joy with it to the point where I made a 16pro40 which worked 100% all the time until I  bought a Pickit2 which in my opinion is worh 3x the price they charge.you just can't beat the price and capabilities not to mention microchip support of this little gem.you will not build or dream up a programmer this good for the money they ask

Here's a pic programmer, maybe something for you?

hi all,

i need a starter kit and development system for Atmel's, like STK500, but cheaper.
any idea?

thanks!
