DRV8353RS-EVM: Using DRV8353rs-evm with STM Nucleo H755ziq eval board.

Part Number: DRV8353RS-EVM

I am a beginner and I have been trying to build a robot where my Nucleo H755zi-q will act as the motor controller. After research on chatgpt I got my hands on the DRV8353rs-evm to power a 3 phase 120 Degree Hall sensor based BLDC Motor. 
Right now, I have a code which generates PWM properly based on the input from the Hall sensor in the motor. I am yet to connect my Nucleo board to the Driver and power my motor via a regulated voltage supply. I am verifying the pwm output by using an oscilloscope.
I have gone through the DRV8353rsEVM user guide, but still a bit confused. 
I will share the circuit connections which I have made so far as well as the code which I am using on
STM32CubeIDE.
Please go through them and let me know if there are any mistakes. 
My current objective is to successfully get the motor running and to understand how the connections will work. Once that is done, I can then focus on the logic behind the movement of the robot.

    Hello,

    Most of the connections look good, but hall sensor signals from the motor should go to the microcontroller. This is because those connections determine the position of the motor, which will determine which commutation state the motor will be in. The microcontroller is the chip that needs these connections, not the DRV, like you have drawn there.

    Thanks,

    Joseph

    Taking a second look, your middle block is the EVM not just the DRV device so this should be Ok. Just make sure you have all the hall connections correct as this is important for commutation.
