TWO STURDY TEMP SENSOR WIRES

sturdy wires probably doesn’t help with temp sensor noise, which is the reason a lot of us have disabled the temperature sensors.

I may have misinterpreted, but felt like jeff was just saying, with a lot of motors… we’re just f’d.

@Deodand

The motor temp problem stems mostly from the fact that not everyone is running the same analog LPF on the motor temp sense and the lack of control on routing of the sense wires in the motor. I think a lot of the hardware has higher cutoff frequency around 100 hz which means noise passes through up to 1kHz. The vesc 6 LPF definitely makes this issue less prevalent. If you want to know why noise is coupled into the motors temp sense all you have to do is look inside a motor to find all the terrible coupling you need:

We’ll continue trying to improve the code to get reliable performance but there is only so far digital filtering can go when aliased samples are taken. On the stormcore we ended up swapping the cutoff freq of the LPF to address this but there isn’t much I can do for all the people using unity’s out there, except to say get a motor with better temp-sense routing.
