MSPM33C321A: Stepper motor board for upcoming Motor control SDK

Keith Barkley

Guru 43715 points

Part Number: MSPM33C321A

I know I am too late for you to actually take this suggestion, but for the upcoming SDK with motor control, are you planning to use one of the Click boards for the mikroe connector on the launchpad? They have several that use TI chips, and it will allow use of the connector to show off the capability.

Also fewer flying wires than if you use an existing TI evm. 8^)

Hi Keith,

I don't believe we have the MIKROE connector planned for the upcomming SDK release. Like this one: https://www.digikey.com/en/products/detail/mikroelektronika/MIKROE-4125/12698691?gclsrc=aw.ds&gad_source=1&gad_campaignid=17336967819&gbraid=0AAAAADrbLljqN9o2e-xlkgS8QzXxWjXtr&gclid=EAIaIQobChMIjJ6GuvaLlQMVNFN_AB0wLRbUEAQYASABEgLr1PD_BwE

Is this what you're referring to? We typically just support using a DRV evm directly as the PWM channels is how we are seeing users drive a motor. The above link seems to be driven by I2C.

There are any number of them. This one uses SPI, though there are some that use the STEP/DIR interface:

My point is that the Click boards are usually much cheaper than the TI EVM's, especially since the TI boards have a MCU that will be bypassed anyway.

Thanks for bringing this up! I'll see what we can do as the hardware is available on the launchpad.

In this thread:

It was mentioned that the Motor control SDK would be out in June.

e2e.ti.com/.../mspm33c321a-motor-control-sdk

Is there any new eta's? Or did I delay it by asking to use a Mikroe click board?

Hi Keith,

Sorry unfortunately it was delayed for this release.
