Multimedia Peripherals

Configure and use communication peripherals such as I2S and more

Create Simulink^® models with the multimedia peripherals such as I2S and more available with STM32 processors. Inter-IC Sound (I2S), is an electrical serial bus interface standard used for connecting digital audio devices together.

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.

Blocks

I2S Mic In	Read audio sample from MEMS microphone available on the STM32F4xx based board (Since R2023a)
I2S Audio Out	Send processed audio samples to audio devices (Since R2023a)
