Communication Peripherals

Configure and use communication peripherals such as CAN, I2C, IPC, SCI, SPI, TCP, UDP, and more

Create Simulink^® models with the communication peripherals such as CAN, I2C, IPC, SCI, SPI, and more available on TI’s C2000™ microcontrollers. Configure the Simulink model to interface with supported target hardware using model configuration parameters. You can map tasks and peripherals in a model to hardware board configurations using Hardware Mapping tool.
