STM32 Electronic speed controller (ESC)

Electronic speed controller (ESC) is a device which can control a Brushless DC electric motor. This page is meant as a place to write down research notes and it is most definitely a work in progress.

Control

The first ESCs were typically controlled by applying a PWM signal to a pin. Since then many other both analogue and digital approaches have been developed. This section list some of these along with benefits and drawbacks.
