I've just started a project "Sensorless BLDC Motor Controller: Modular System" on Kickstarter. It is open source hardware/firmware project.
https://www.kickstarter.com/projects/946939931/sensorless-bldc-motor-controller-modular-system
Event driven finite state machines (FSM) approach was used for this sensorless BLDC motor controller firmware. The programming language is C and there is no operating system. It was implemented by myself from scratch based on the well known motor control, other algorithms and the firmware is a totally open source product.
What the implemented firm
