Is it possible to use Arduino UNO programmer for other AVR microcontrollers? I got an Arduino UNO which I started using with microc for avr to add more customizations.
I'm wondering if it is possible to use the Arduino UNO programmer to program other AVR microcontrollers (I know that it is possible using ATmega 328p and 168).
The AVR microcontrollers that support ISP are all tinyAVRs other than the 4/5/9/10/20/40, and all megaAVRs.

The ATtiny4/5/9/10/20/40 requires TPI (Tiny Programming Interface). AVR XMEGA devices require the use of PDI (Program and Debug Interface). Neither can be programmed using ArduinoISP.
