This is the source code for the latest version of the 64 channel servo controller as detailed here.
This is an ATMega168 version of the controller that was originally developed for the ATtiny2313 but which was ported to the ATMega when I ran out of memory on the ATtiny.
The schematic required is similar to the one for the ATtiny2313, I'll produce a new one for the ATMega168 when I get some time. Note that we now use pins 0-3 of port B and port C rather than just 0-7 on port B, so the connections for mux chips 5 through 8 will come off of port C.
Source code is available here.
