MSPM0G3507: MSPM0G3507

Hi, thanks for the question! Yes, looking at the boosterpack pinout for the BOOSTXL-DRV8305EVM, it will work just fine with the launchpad since the pins match up correctly. Hope this helps!

Hi Brian,

I am going to use the SW-MSPM0G3507 application written for DRV8316.

But the connectors for both are a bit different ( Halls + other)

Will it not be a problem?

I see that the SCS and PWRGD signals are different. if you are using a launchpad and the boosterpack, you could place a jumper from PB12 to PB17 to fix the pin mismatch for the SCS. For the PWRGD, there could be an issue there since it is connected to the NRST of the M0. One possible solution for this would be to break the trace connecting to the boosterpack. This is assuming you don't need the PWRGD signal for your application. If you need the PWRGD, you could break the trace on the M0, then jumper the PWRGD signal to another open GPIO to monitor the status.

You could also try disabling the NRST pin in sysconfig to see if that resolves the mismatch there.

Thank you Brian

I will try it and I will see

Hi Brian,

What about the SPI commands from MCU? Both DRV8305 and DRV8316 have some different registers.

Hi Zbyno, the SPI commands will be something you implement in the MCU code based on the motor drive EVM you are using. If you are using both simultaneously, you will need to assign a second nCS pin for one of the devices so you can communicate with both on the same bus.

Hi Brian

I only want to communicate with the board DRV8305. I thought DRV8305 had some other register than DRV8316, which was written SW.

Hi Zbyno, were you able to get the M0 and DRV8305 to successfully communicate?

Hi Brian

I will try to do it. But some advice could be positive

Hi Zbyno, I would look at some of the motor control examples in the latest M0 SDK as a reference. There are several for sensored/sensorless FOC motor control which also include the motor control library.

Thank you Brian

I will wait for your answer

Hi Brian

Can your SW work without the signal from Hall-sensors?

have a nice weekend

Thanks, Brian,

I try it without Hall sensors
