Pmod DPOT to replace Mechanical Pot

[TommyFlynn]

Hi,

I wish to replace a mechanical potentiometer on a motor control board which is used to control the speed of a motor with a digital potentiometer. This will allow me to control the speed of the motor using LabVIEW on a PC. I have a myRIO 1900 series.

I am looking for some help with the wiring involved in the removal of the existing pot and replacing it with the digital pot.

Thanks.

Hi @TommyFlynn,

The physical swap in terms of attached wires on the potentiometer should be straightforward in terms of the outputs on them. The swap you are looking to do won't be as direct as you might be hoping it will be because you would need to integrate SPI connectivity to configure the material. I'm not as familiar with LabVIEW (and haven't used a myRIO) in terms of setting up the SPI connectivity.

Let me know if you have any questions about this.

Thanks,
JColvin
