Hi,
I'm building dual bldc motor driving board, using the ST Motor control library. MCU is STM32F303VC. According the motor control workbench, I can select ADC3/4 plus TIM1 for motor 1 and ADC1/2 plus TIM8 for motor 2. But it appears that it's hard coded in the library ver 4.3 (function R3_4_F30X_Init) ADC1/2 always to be used with motor 1. I reversed the code and finally my board can run a bldc motor. Should I change any other function?My second question is about maximum
achievable dual FOC frequency with STM32F303 at 72MHz?
Maximum for me is 20KHz PWM with torque/flux execution on every second PWM period, using CCMRAM (motors with hall sensors).#motor-control-foc-library

The question has been moved from the "Motor Control Hardware" section to the "STM32 Motor Control" section (the question is about the STM32 MC SDK).
Best regards
