Hi,
I have started working on Electronic speed controller, I need firmware support for my ESC which supports sensor less trapezoidal control algorithm.
Thanks

Hey Anmol,
Thank you for the question. I will aim to provide an update before the end of the week.

Hi Anmol,
From a firmware perspective we are limited in what we are able to support as our expertise is on the DRV side. What firmware questions do you have? Are you using a TI microcontroller such as a C2000 microcontroller?

Hi Anthony,
We are exploring the solution that can support sensorless trapezoidal control, we came across solution available on TI i.e. Instaspin FOC and Instaspin BLDC.
Is there any solution that can sensorless trapezoidal control.

Hey Anmol,
Our DRV8300EVM does not use sensorless trap commutation. But we have a few EVMs that use this implementation such as DRV832xEVM.

This is a demo FW developed by our MSP team as we focus on motor drivers and are limited from a firmware perspective.

Hi Akshay,
As i can see, it supports sensored trapezoidal scheme not sensorless.
Thanks
Hi Anmol,
I just want to be clear that the device itself can be used in sensorless trap applications, however the EVM was not designed for sensorless trap so a board would need to be designed specifically to have the necessary circuitry to support sensorless trap. As Akshay mentioned, there is some example code that can be referenced from other devices to help aid in sensorless trap code development.
