I've managed to get communication up and running from labview to the
cybermaster, and noticed as I was testing different resistors as sensors that
the values returned is following a curve. This suggests to me that the inputs on
the cybermaster are constructed in such a way that I can apply a voltage to the
input instead of just a resistor. It might have to be through a 1:1 coil in
order to galvanic (??) seperate the input from the sensor. Can anyone verify
this?
Also does anyone know the opcode for resetting the tacho counter?
/regards

| (...) 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 (...)

| Hi John, (...) maybe that curve corresponds to a 10k Pullup-Resistor to 5V? (...) Yes, on the RCX it is 0 to 5V with 10 bit resolution. I'd suppose the Cybermaster is compatible with that, except that it cannot provide power to active sensors. (...) (18 years ago, 27-Aug-06, to lugnet.robotics.cybermaster)
