Hi Everyone,

Anyone out there got a schematic and source code for a programmer for a serial interface ?

I have the stuff for the parallel one, and that works fine, but I sit at a windows nt machine, and nt and taking direct control of the parallel port do not get along.

I am assuming the serial version of the programmer from Atmel probably has one of the avr chips at its heart. It would be nice to have a serial programmer that worked with the software in the avrstudio. It would be easy enough to design a serial programmer from scratch, but if it works with the avrstudio software, all the better - save some design and better integration.

Thanks in advance to anyone who has this.

As you are probably well aware, the STK500 allows for integration with AVRSTUDIO and supports both parallel and serial programming. I believe there is an expansion header from the board so that you can ISP on your own board. Maybe the AVRFREAKS guys can confirm whether it is functional.

Atmel will also be coming out (soon I hope) with a programming dongle ATAVRISP50. This dongle contains the same micro used for programming on the STK500.

If you require something immediately then let me know.

Jon you know who I am.

Thanks Marc,

My brain must have been in powerdown mode when I read appnote 910 originally. I went to it this morning and had a strong sense of deja vous, so I must have read it before (I thought I skimmed through them all).

That is exactly what I needed, Thanks again.

Note - another reason I want to just build one, is it is more convenient to just leave wires hanging from it to insert into protoboard than to have a connector, and then have another adaptor plugged in there, and then wires to the board. I have the double adaptor thing setup now, and it is not too pretty. (I always feel bad buying something and then cutting off pieces right away.)

I can confirm that STK-500 can be used to program other systems through the ISP header. Please make sure you open the VC TARGET (or something like that) jumper though (as specified in the STK-500 manual).

Also, it works the other way around. You can program the onboard chips on the STK-500 through the ISP header (though the other end) with some other programmator. I did this under UNIX since the versions of UISP that I have do not support STK-500 protocol.
