Interface 5 motors requiring n-Pulse Generation mode

I asked a question earlier on how to generate n-Pulses from STM32 to drive a servo like interface -> STM32 n-Pulse Generation, and it worked. This feature is available only on TIM1/8. Is there a novel way of interfacing 5 motors to one F7?


I am trying to interface 5 Teknic Clearpath SDSK motors to STM32F7 Nucleo Dev Board. They are Brushless DC motors with a stepper like interface. The motor moves a set distance based on the number of pulses it receives. The speed is determined by the frequency of the pulses, like a stepper motor. I can hook up the two motors to TIM1 and 8, and the rest with a feedback to counter,. DMA buffering won't work, as I rely on the pulses sent to determine the current position of the motor. I am just looking for a better solution here.
