Replace ATTiny2313 with ATMega8

Post by diplomat_rk »

Hi to all

i downloaded and made USBTiny ISP projects and it work very nice. thanks Ladyada. :D

now i want to replace ATTiny2313 with ATMega8! because ATMega8 is cheaper than ATTiny2313 in the my country. but i can't work with AVR Studio , my favorite compiler is Bascom.

can anyone help me to retouch USBTiny ISP Programmer source code for ATMega8?

Hi!

If you want to use the atmega8 or atmega88 you should look at something like this: http://www.fischl.de/usbasp/

Better in what way? You could look at moving the USBTiny SW to the mega8, which would give you essentially USBTiny behavior with USBASP hardware. Or, once you have a mega8, you could consider other firmware for programming (V-USB + ArduinoISP, for instance.) USBTiny's major feature is fitting in the 2k CPU, but as you point out, that's not necessarily cheaper, and it just barely fits, so there isn't much room for improvements...
