Controlling two servo motors with one STM32 MCU

Kmax18 · ‎2021-05-23

For a new motion control application it would be beneficial to control two servo motors (in velocity control mode) with one STM32 MCU. It would require to generate two PWM signals based on Hall sensor feedback from two servos. The two motor velocities are not identical. Do any of you have experience with that configuration? Is it technically feasible? What are possible pitfalls? Thank you!

They should all able be able to generate servo signals.

A TIM programmed with a 50 Hz period can typically drive 4 pwm channels with different pulse widths. You can update the widths at the 50 Hz / 20 ms Update
