ummm how about some info first? What programmer are you using? What is it currently in terms of pin count? What are you trying to program? Why does the programmer need to be converted and not the circuit?

Im assuming your talking about the AVR ISP MkII? Which is a 3x2 pin?


-Edit-
And BTW, this technically isnt a software question, just so you know.

Ok I found your other post so now I know what you want to do. Ill write a small tutorial complete with pretty picture and post it in a second =)

It is much easier to just incorporate a new 3x2 header. Ill show you how, its much easier to do. Stand by...

-Edit-
In the meantime, look over this post:

It will help you

ok..... so i was gona convert my isp mkII to 10 pin but now i am told it is better to desolder. I have looked over all the posts on fixing it but all those numbers and stuff dont help me much.... i really am a noob... the only reason i could do the rest of the tutorial is cuz  it told me exactly what to do... What i will probobly do is put a pic on of my board and meybe someone could circle what has to go on paint and then put it on here.

edit-


meybe there is already a pic of a board on this site.... and someone could just circle what parts have to go on that... I look now...

All the numbers you see on that page are pin numbers.

Dont desolder what you already have. Instead, create a new 3x2 header and solder it somewhere else on the board. Then do the following:
Use this picture of the micro-controller(aka "uC", "MCU") as a reference for the rest of what im going to tell you: (Click for a larger picture)


Ok, heres how you identify which pin is which for the 3x2 header.
~A~
When you open up the header box (The translucent blue thing with the lights and stuff) and you take off the cable, you will see one of the pins has a 1 next to it.
~B~
Looking at it with the USB part facing upwards and the ISP part facing downwards, you should see this:
 : : :
1
~C~
That is pin one. So that means:
2 4 6
 : : :
1 3 5
||||||
||||||
|cable
||||||
||||||
2 4 6
 : : :
1 3 5

understand so far?
~D~
Now that you have identified which pin is which on the ISP Cable, you can start to solder all the connections

This image shows the 3x2 header instead of the 5x2 header. I color coordinated everything so you should be able to follow it pretty easily. Just remember, if you rotate the direction of the 3x2 header, you must make sure pin 1 on the cable still lines up with pin 1 on the header.


Hope this helped! If not, post :)

alright that looks like it helped alot... im on vaca for like 3 days so i am away from my board. When i see my board i will know what other questions to ask. but right now i just want to know where i should solder on the 3x2 header? Does it matter where? DO i have to connect it to the 5 pin? k thanks for all of your help!

You can actually omit the 5x2 header completely and just replace it with the the new 3x2 header.

It doesnt matter where you put it on the board, just as long as all the connections go to the right places and that you hook it up correctly.

Personally I would suggest de-soldering the 5x2 header and putting the 3x2 in its place so you dont clutter your board, but I bet some of the elders here would say just add the 3x2 without removing the 5x2 so you get diversity or w/e lol

IMO it makes it easier to remove the 5x2 and put the 3x2 in its stead like I have in the picture.

Basically all thats important is that everything is connected where is should be, and nothing is connected where it shouldn't it.... BTW I keep getting interrupted so sorry for any and all repetitive info.

yep, you could take out the 2 pins on the end to make it a 3x2 but you will need to redo the wiring according to the 3x2 ISP cable specs I posted above

hope this helps!

as long as you have these connections made(and of course the ones for the battery hookups and sensor and motor headers etc etc)

You will be good to go

but make sure you dont accidentally short circuit anything or anything like that cuz thats bad lol
