Hi, I am quoting from a previous question posted on this forum but hasn't been answered. I wanted an answer to the exact same question:I am using the STEVAL-SPIN3201 board to control a BLDC motor.I want to implement a position controller, so I need t...

Hi, I am trying to implement simple six step motor control using the STEVAL-STSPIN3201 board. However in order to do this I need to be able to switch off both the high and low side MOSFETS in one of the three phases U,V or W. For example for the firs...

Thanks for your help. I have a much better understanding now. Will try and run the motor with available six step example.

Hi Enrico, sorry for the late reply. I am trying to understand the diagram you attached. So it looks like the high side gate voltage is HIGH-Impedance not HIGH (i.e. in the middle between low and high?). The low side gate voltage is LOW on your plot....

Your PWM frequency maybe too high. Anything above 15-16kHz caused problems as the PWM frequency is also what's used to trigger FOC calculation, and if the calculation takes longer than the period of the frequency you will get FOC error.

Yes the gate to the high side mosfet is on. I don't see how it can be software because all I am doing is initializing all the GPIO pins in CubeMX like this:static void MX_GPIO_Init(void){ GPIO_InitTypeDef GPIO_InitStruct = {0}; /* GPIO Ports Clock En...

I understand that HSx and LSx can't be 1 at the same time. The issue is I can't get them to be 0 simultaneously (I have confirmed this by measuring the voltage at the gate of the external high side and low side mosfets). Without setting up the timers...
