Dagor Brushless Motor Controller

Two new videos of the actuator and the Dagor Controller

New documentation website :)

Visit Home - Dagor-Brushless-Controller to learn more about the controller. 

If you're interested in a board of the alpha run please let me know here: https://forms.gle/S7gtZfyXZeQ7XbT29

The Dagor Controller uses a low-side shunt resistor for current sensing, this posed a challenge to sync the ADC measurement with the on-time of the low-side FET of each phase. With the ESP32's MCPWM unit I managed to do this and get good current readings.

Good current readings:

Bad current readings:

This happens because there's no current flowing through the shunt resistor when the low-side FET of the phase is off.

I will make an alpha run soon. Please fill this google forms if you're interested so I can have an idea how many boards I should have ready:

New cheap motors for further testing.

5010 (not really) 360KV brushless motors.
