Reading HW ESC telemetry

Post by jweber » Thu Sep 15, 2016 6:44 pm

Does anyone have a description or better yet Arduino code to read the telemetry output from HobbyWing ESCs? It would be nice to read that and then use the OpenXSensor code to port it directly to the RX. There was a description of the v3 output, but the v4's have more sensors, but no description.

Thanks

Could you give more information about "telemetry output from HobbyWing ESC"

What data is available?

"It would be nice to read that and then use the OpenXSensor code to port it directly to the RX" Nice and what?

The v3 HobbyWing Platinum ESCs can output throttle value, PWM and RPM. It's in the user manual for them in the developers section

But what is more interesting is the platinum v4 ESC you get the following information:
battery voltage, current, throttle, PWM, RPM, FET temperature, Caps temp

There's just nothing that describes the protocol that I can find. jlog has been modified so that it can read the values and report them up from the programming port on the ESC.
