Design Team Six - Stepper Motor
Texas Instruments has developed an evaluation module for their newest motor driver the DRV8824. This evaluation module comes with a MSP430F1612 on board to control the motor driver. The DRV8824 manages the pulse-width modulation (PWM) while allowing for the MSP430 to control the DRV8824.
Texas Instruments has moved to a more modular design for their motor drivers. They are providing the analog DRV models with sockets for their ControlCards. These ControlCards contain their popular microcontrollers, and allow for motor control with interchangeable microcontrollers.
To fit the DRV8824EVM into this modular design the board will be partitioned into two parts, a motor driving board and a ControlCard. The motor driving board will have a DIMM socket that will be able to accept multiple ControlCards that can all have different microcontrollers onboard. The ControlCard will contain the MSP430 microcontroller with a matching pin out. The multiple microcontrollers on the ControlCards will be able to be programmed to control the DRM8824 motor driver, and provide a modular approach to motor control.
