Question
Is it feasible to control two motors with one STM32F103RB MCU?
How can we determine if the computational power of only one STM32F103RB MCU is sufficient for controlling two BLDC motors? System clock is 72 MHz. For my current application I believe it is feasible due to low motor velocities, here up to 5 rev/sec per motor. However, is a good estimation technique available? Motor commutation will be based on Hall signals only (no field-oriented control, FOC). The Hall signals will be captured using the advanced timers 1 and 8.
