CCS/TMS320F280049C: Sample code for Motor Control

Part Number: TMS320F280049C
Other Parts Discussed in Thread: BOOSTXL-DRV8323RS, C2000WARE-MOTORCONTROL-SDK, C2000WARE, TMDXIDDK379D

Tool/software: Code Composer Studio

I want to prototype a consumer product using the F280049 Launchpad and the BOOSTXL-DRV8323RS (once this is working, we will spin the components into a custom board)

I am interested in Torque control at low speeds of a Permanent magnet brushless DC motor (Three phase). I determined that InstaSpin FOC will not work at my operating speeds. Do you have sample code for doing sensored control using hall sensors that we can use as a starting point for our application? The Boost board has trapezoidal commutation sample code but it produces poor torque control (we tried it out). What is the best place to get sample code that will get us close to running so we can modify it for our application?

Regards,

Neil

C2000 doesn't have hall sensor based sensored-FOC, but there is a reference sensored-FOC with an encoder on F28004x in motorControlSDK as the below link.

Thank you. I downloaded the MotorControl- SDK but I'm not certain that I am looking at the right code. Is this the right path:

[install dir]/C2000Ware_MotorControl_SDK_2_01_00_00/solutions/common/sensored_foc/source/dual_axis_servo_drive.c

or is there a different file to start with?

Is this the file you were referring to?

[install dir]/C2000Ware_MotorControl_SDK_2_01_00_00/solutions/common/sensored_foc/source/dual_axis_servo_drive.c

Thank you.

It's ok, but it's for the dual motor. You might refer to the example in the below folder, but it's based on IDDK with controlCard. So, you have to make some changes to support your own board/kits based on either one of these two projects.

Hi,

I was following the example project in that folder. I noticed that the BoosterPack has the VDC bus voltage input (VSENSM) connecting to PGA2/4/6_GND on the launchpad. The Boosterpack is expecting to connect to an ADC input on that pin instead. Would I need to cut the booster pin that connects to the F28004x launchpad there and jumper to a different ADC input pin? Or is there a better solution?

Regards,

Neil

Yes, you have to cut the connection and add a jumper to connect the dc bus voltage sensing signal to an ADC channel.
