I am developing bldc drives using stm32f103c8t6 MCU. And by using inverter circuit we drive the bldc motor using stm32. Block diagram of drive is shown belowUsing register language, we coded logically for 6 step commutation. And that works fine.But I would like to know if any library is available for stm32f1** (for trapezoidal control). So that i able to see difference and get corrected myself.

Hello,

Th X-CUBE-SPN7 package may help you: https://www.st.com/en/embedded-software/x-cube-spn7.html

It provides a 6-Step implementation that targets STM32F103 devices.

Best Regards
