C program to control pwm of a bldc motor using nuvoton motor driver board KA44143A through stm32f407 board.

• Hi Imran, 

  
  

  Refer to the manual and datasheet, could be download here: 

  https://www.nuvoton.com/products/motor-drivers/motor-driver-ics/brushless-dC-Motor-drivers-BLDC/ka44143a/

  
  

  It's a easy-to-use BLDC driver which can control the rotation speed by PWM or Analog input depends on TRI pin.

  And rotation direction could be set by FR pin. They can be set by the jumper on the evaluation board.

  
  

  Please try to generate PWM from STM32F407 connect it to VSP input on the evaluation board.

  Also recommand you their powerful MCU dev board.
