Connectivity Peripherals

Configure and use connectivity peripherals such as CAN, FDCAN, I2C, MQTT, SPI, UART/USART and TCP

Create Simulink^® models with the connectivity peripherals such as CAN, FDCAN, I2C, SPI, UART/USART, TCP and more available with STM32 processors. Configure the Simulink model to interface with supported target hardware using model configuration parameters. Configure the Simulink model to interface with supported target hardware using model configuration parameters.

Support for STM32 processor based board with Simulink uses STM32CubeMX graphical tool. STM32CubeMX tool is a graphical interface that you can use to configure peripherals of STM32 processors and generate peripheral initialization code for the STM32 processors that you select. You can configure the STM32 Processor-Based Boards to use the STM32CubeMX project with Simulink to generate code and deploy the code to the hardware.
