Driver for I2S communication (using SPI peripherals) for some STM32 microcontrollers
Documentation

STM32 I2S driver

This library provides driver and abstractions for I2S communication using the SPI peripherals on some STM32 microcontrollers.

Differences between STM32 models

According to application note AN5543, there are four major versions of the SPI/I2S peripheral used on STM32 microcontrollers:

  • 1.2.x: F1, F2, F4, L0, L1
  • 1.3.x: F0, F3, F7, L4, L5, WB, WL
  • 2.x.x: H7, MP1
  • 3.x.x: "Most of STM32 devices launched in 2021 or later"

This library currently has code for SPI version 1.2 (STM32F1, STM32F2, STM32F4, STM32L0, and STM32L1).

Status

This library has been tested on a few different STM32F4 microcontrollers. The other models that use the same SPI version (F1, F2, L0, and L1) may work, but we haven't tested any of them. Trait implementation and working example will be availaible in stm32f4xx-hal.
