Decent DIY AVR Programmer

[epineh]

Anybody have one ?

I have an ISP programmer from Jaycar borrowed off a friend, and tried the old four resistor version on the parallel port...nothing working so far.

Call me old fasioned but it seems a little odd to have to buy a $200.00 programmer to program a $6.00 chip.

Trying to program a 2313 btw.

Cheers.

Russell.

epineh,
What OS are you using? (Windows Linux ...) I can give you some points as to where to look....

Hey armstrong, I use both windows and linux, I guess I would prefer windows as far as physical PC location goes, I am trying a design from here at the moment :

any other help would be great.

OK, I am almost alway running in Linux but may be able to help anyway! I have used the parallel port programming method using sp12 and avrdude. (both these will use the same four resister parallel port programmer) Both of these have windows driver software. Avrdude has a configuration entry for the programmer you have. Sp12 is parallel port only.

Ponyprog should work as well!

So you have built this programmer yourself or borrowed a working programmer from someone else?

What do you have for a circuit for your 2313? From the diagram it appears that you need to have the 2313 powered externally. There is a reset line to the micro, it is pulled up by the 10 k resistor to +5 - power that comes from the board the 2313 is mounted on...

So first thing lets check to make sure you have power on your microprocessor and the 10 k pullup.

Here are eagle files for three different programmers. You may want to change them from the 6 pin to the 10 pin isp.

I almost had success with the programmer I linked earlier, it firstly said I selected the wrong AVR from the list, which I double checked to be correct, so I tried the auto detect setting (Using PonyProg) and it said programming successful but I don't think it was.

I will have a look at the links given and find out some more.

I had a look at the boards you posted Phil and they look very similiar to the programmer I am using, if I can't get my version going I will try one of those.

Cheers.

All three of the ones I posted I've built and they do work. Software compatability thought I prefer the ones that work with ponyprog.

Try the Atmel AVR dragon http://search.digikey.com/scripts/Dk...ATAVRDRAGON-ND

I am sorry I did not read the DIY part...., anyways, this one is only $51.00

[epineh]

OK well I have had success, it turns out that I didn't have the configuration bits set properly, namely the external oscillator, fuse lock bits were left unprogrammed luckily so I don't have to buy more chips.

Thanks to all who offered help, it is very appreciated.

A very simple one is the STK 300, if you have a parallel port of course.

I've done my on veroboard/stripboard and it has been working very well.

I built an AVR programmer several years ago, dont remember which plans I used but it only cost me about 10 bucks worth of radio shack components. It worked okay, but I later bought an STK-500 and tossed the old homemade one. Check at AVRFREAKS and you'll find all you need to know about AVR's.
