Programming over ISP Using The FTDI C232HM Cable
The above is a quick reference pinout for the cable.
Commands
Presuming you’re using the latest avrdude (older versions didn’t support or have the definitions for the avrftdi stuff), you can call the cable up as a standard programmer as c232hm
:
avrdude -c c232hm -p ............
etc.
Setting Up
There’s always issues trying to get these cables to work so I can’t cover them all here.
If I do however have to set up another windows or linux install to work with the cable then I’ll surely document it here. I’ve done it enough times to know I should’ve just bought a proper programmer.
Windows
You’ll want to change the cable’s driver using zadig to WinUSB I think. (Or was it libUSB?…)
