Part Number: DRV8313
HI,
I have been successful driving a DRV8313 with multi wheel robotics using Gimbal motors like the small ones found on quad copters. Currently I use an ESP32 and a table array to create the waveforms needed for the drv8313. This works ok but I would like to try and improve the smoothness of the drive and increase speed and torque.
The esp32 datasheet

I guess I am looking to measure some BACK EMF of the motor coils and use it to adjust the phase skew in an attempt to reduce some cogging.
Im looking for advice suggestions for components to have some sensor feedback to a Microcontroller.
I could probably write the software if I had a general idea of how to also setup the hardware. I have a number of free input GPOI0 pins to read voltages.
Any how i have looked through most of the internet for quite some time to get to this point but I am stuck
Any help greatly appreciated also if you ask questions I will try to be quick to respond.
Cheers
Adam
