System Peripherals

Configure the direct memory access (DMA) parameters to modify the ePWM duty cycle. Using DMA, the sine wave data is copied from a look-up table to the ePWM compare register.

Use the Control Law Accelerator (CLA) available on some of the TI® processors using C2000™ Microcontroller Blockset.

Use C2000™ Microcontroller Blockset to run a Simulink® model on Texas Instruments™ C2000 hardware.

Manage the voltage mode control (VMC) algorithm for a closed loop DC-DC power conversion system by using the Control Law Accelerator (CLA). An auxiliary software current protection loop is managed by C2000 CPU. In the TMS320F28379D and similar processor families, the CLAs execute the hard-realtime portions of the algorithm can connect with hardware perhipherals such as ADC's and PWM's. The C2000 CPU is better suited for hard real-time portions of the algorithm that require multitasking, handling of asynchronous events, and communication with other cores. While this example extends the DC-DC buck converter developed in the DC-DC Buck Converter on MCU example, the strategy presented can be applied to any design where a resource intensive hard real-time process executes on the CLA and real-time multi-tasking processes run on C2000 CPU.

Use the Input, Output and ePWM X-BARs available on some of the TI® processors using C2000™ Microcontroller Blockset.
