Hi there, my current project is to build a controller for a sensorless BLDC motor using a MSP430G2553. I want to realize trapezoidal control with Back-EMF/zero-crossing detection. I plan to detect zero-crossing with the Comparator(CA2/3/4 vs. CA1) and generate PWM using Timer1. Timer0 will be used for things like 30 BLMC_.zip

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

Hello, I wrote a very simple PWM Code for my Brushless DC Motor (incl. ESC) and it works very good (I don't use any Potentiometers.): int motorPin = PF_1; void setup() { pinMode(motorPin, OUTPUT); } void loop() { analogWrite(motorPin, HIGH); delayMicroseconds(1000); analogWrite(motorPin, LOW); delayMicroseconds(19000); } I need 50Hz (1/50=20us). The Motor breaks when the first delay is "1000us" and the second is "19000us". The Motor arrives highspeed when the first delay is "2000us" and the second is "18000us" So my dutycycle should be between 5 - 10% What
