Thanks to Michael Barrett Andersen who knew that the opcode was 0x11 I now have
control over the tacho counters as well:
0xFE 0x00 0x00 0xFF 0x11 0xEE 0x01 0xFE 0x12 0xED
| Header | opcode | motorID | Checksum |
MotorID is: 0x01 0xFE or 0x02 0xFD or 0x03 0xFC
Go see http://graphics.stanford.edu/~kekoa/rcx/index.html
and http://members.home.nl/b.vandam/robots/crack.html
for details on opcodes and how to calculate checksum
Now that's sorted I just need to figure out if it's possible to apply a voltage
to the inputs.
