ftisp: USB-to-ISP Programmer

Ftisp is a command-line utility that allows program AVR processors via an USB chip FT2232 or FT232R.
Ftisp uses the fast synchronous bit-bang features of this chips.

FTISP can work with any FTDI-based USB-to-serial convertor with FT2232D or FT232R. These chips allows bit-bang operations, so they can emulate ISP protocol just with a little bit of magic software.
