st7 isp programming

Does anybody have C code for ISP programming of micros AT89, AT90 and ST7 via parallel port.

Thanks

Why don't you try to use Ponyprog? Or use a command line programmer and make a Batck File.

What variant of the ST7 are you trying to program, the early types used ISP - the latter use ICC.
Using a parallel port is very easy with the ICC variants, slightly harder with the ISP variants

You can try with the Freeware version of CodeVision AVR.
The web page: https://www.hpinfotech.ro/
I do not know if you can download it from there..., so try.
Then you can programm the unit with a home made parallel port programmer, using In System Programmer for Atmel.
