Telemetry ESC32v3

Postby snehaljain018 » Tue Aug 23, 2016 5:39 am

Hi guys,

I am working on a research project that involves a bench testing of a new control mechanism of a coaxial rotor. My setup involves a DJI E600 motor mounted on an ATI F/T sensor. The motor has a 10-bit magnetic absolute encoder. The data from the force cell, along with the encoder data is being collected by a NI DAQ, which is being read and saved by an appropriate Labview VI program at 1kHz.

I am driving the motor using an ESC32v3, which I believe is an amazing controller, given it's telemetry and I/O options. The ESC32 Configuration Utility is amazing, but it allows live telemetry for only upto 10Hz. What is the best way to store the Voltage, Current, RPM, Duty and Temperature of the system at high rates (~1kHz)?

Any help would be appreciated.

Thank and Regards!

You would need to create your own binary protocol client which connects to the ESC and requests the needed telemetry data. The data rate can be set in this protocol. See ESC32v2 source code for an example of this protocol in action.

Thanks ;) But why do you think telemetry rate is limited to 10Hz? You can set it higher, up to 1KHz. There will be some practical limits when using UART connector, perhaps 300-500Hz maximum, but over USB you should be able to get even higher rates.

Cheers,

Yeah, very stupid of me. I figured that out later. Thanks! :)
