July 12th, 2008 USB ISP Programmer For AVR
There are dozens of projects like this one on the web, but it’s nice to be able to chose the one you like most. Nothing special with this AVR ISP programmer, maybe just the idea that the author build it because hi’s hold programmer was working trough serial connection and as most modern devices work on USB he decided to make his programmer work on USB.
So, the solution was to replace the two transistors, that were used to adapt the RS-232 voltage levels to TTL voltage levels, with a USB to RS-232 chip such as FT-232BM.
