MSPM0G3507: Pin Configuration Issue

Hi,

Could you provide more details about the difficulties you are having?

Please annotate your schematic, so I can see which pins are supposed to be configured as a PWM / ADC inputs

Hi,

I’m working on running a 230V BLDC motor using the MSPM0G3507SDGS28R device. For this application, I need six PWM outputs to generate motor control signals and three ADC inputs for bus voltage sensing, current sensing, and temperature sensing.

I’m facing difficulties configuring the pins to support all six PWM outputs and the three ADC inputs as per the schematic. I’ve attached the schematic with annotations indicating the pins I intend to use for the PWM and ADC functions.

Hi,

I am assuming that you are running into resource conflicts. You may have to shift some pins around in order to find a configuration that works.

If you tell me more about what timers you want to use, and any other relevant requirements, then I could assist further.

Hi,

Thank you for the suggestion.

I’m planning to use the advanced timer for generating six PWM signals, and I also need to allocate resources for one UART, one I2C, and three ADC channels.

Hi,

My apologies for the delay -- I was out of the office for a while

I would start by assigning the pins based on the most critical signals, and based on the peripherals that have limited pins.
