1 Introduction

MSPM33 Motor Control is a middleware package integrated within MSPM33-SDK and to allow users to spin motors in short time using small-scale, simplified MSPM33 firmware examples with popular motor driver designs and topologies. Table 1-1 shows the types of motors and motor control algorithms that are supported for industrial and automotive applications.

MSP Motor Control provides an abundance of resources inside MSPM33-SDK to support all motor control developments. Examples of resources include:

  • Supported hardware designs using MSP control boards (LaunchPads) and motor driver evaluation modules (EVMs)
  • Supported interposer board that sits between MSPM33 LP and DRV EVM with targeted DRV EVM compatibility
  • Production-ready software using a Hardware Abstraction Layer (HAL) for scalable MSP and driver support
  • Easy-to-evaluate Graphical User Interfaces (GUIs) to spin the motor in less than 10 minutes
  • User guides and supporting documentation in TI Resource Explorer
MSP Motor Control with MSPM33-SDK Development ResourcesFigure 1-1 MSP Motor Control with MSPM33-SDK Development Resources

As shown in Figure 1-1, MSP Motor Control is embedded within MSPM33-SDK as a middleware package that can interface with Non-RTOS and RTOS drivers, MSPM33 DriverLib support, and graphical configuration tools such as SysConfig. Additionally, MSP Motor Control can pair with other middleware examples such as CAN and LIN drivers, and subsystem code examples can easily be added on top of MSP Motor Control to quickly build software designs. This provides a simple-to-use ecosystem to evaluate motor control for a wide variety of applications using brushed-DC, stepper, BLDC, PMSM, and ACIM motors.

MSP Motor Control requires the following tools:

  • Code Composer Studio™ Theia v20.4.0 or newer
  • MSPM33-SDK V1.00.00 or newer
  • Support for IAR Systems and Keil embedded development tools
