So even though I said FTDI adapters are not for programming 'raw' AVRs, it turns out you can 'convince' the chip to do it with a bit of manipulation. ( and ) If you have an FTDI friend or other breakout where you can get to the DTR line, I found a way to do it that requires soldering a wire but no AVRDUDE/driver messing. The trade off is that it is really slow - good for maybe burning a bootloader on, not good for day-to-day AVR development Turn over the FTDI friend, and solder a dot of solder onto the DTR pin on the bottom left. P4m900-m4 audio drivers for mac. A common reason for wanting to program an AVR is to put the Arduino bootloader on there, in which case, you may not have WinAVR installed. Luckily, avrdude is there, its just 'hidden' in the IDE package (for Mac users,you need to actually 'explore' the App) if you're running windows, go to the folder where you have the IDE installed and go into the hardware tools avr etc folder to open up avrdude.conf OK! Now that you have avrdude.conf open, find the string ponyser, then add the following bold text right before hand so the avrdude.conf looks like this. # some ultra cheap programmers use bitbanging on the # serialport.
