Main Changes

Maintenance release

Maintenance release of STM32CubeG4 (STM32Cube for STM32G4 Series) Firmware package supporting STM32G431xx/41xx/71xx devices, STM32G473xx/83xx devices and STM32G474xx/84xx devices.

A Discovery kit, B-G474E-DPOW, is introduced in this release to enable demonstration of Buck and Boost in voltage mode, High brightness RGB LED control and USB audio streaming.

In the STM32CubeG4 MCU Package, examples and applications projects are generated with the STM32CubeMX tool to initialize the system, peripherals and middleware stacks. User can open the provided ioc file in STM32CubeMX to modify the settings, add additional peripherals and/or middleware, to build his final application.

Demonstrations binaries are no more delivered within the STM32CubeG4 MCU package. They are available for download, in addition to their required media files if any, in a standalone package accessible through each hardware board official webpage. Please refer to the corresponding demonstration binary readme.txt to get webpage for each board.

Main Changes

First release

First release of STM32CubeG4 (STM32Cube for STM32G4 Series) supporting STM32G431xx/41xx, STM32G471xx, STM32G473xx/83xx and STM32G474xx/84xx devices.

In the STM32CubeG4 MCU Package, most of the examples and applications projects are generated with the STM32CubeMX tool to initialize the system, peripherals and middleware stacks. User can open the provided ioc file in STM32CubeMX to modify the settings, add additional peripherals and/or middleware, to build his final application.
