Introduction to STM32CubeMX

1 What is STM32CubeMX?

STM32CubeMX is a graphical tool that allows a very easy configuration of STM32 microcontrollers and microprocessors, as well as the generation, through a step-by-step process, of the corresponding C initialization code for the Arm^® Cortex^®-M cores or a partial Linux^® Device Tree for Arm^® Cortex^®-A core.

The first step consists in selecting the STMicroelectronics STM32 microcontroller or microprocessor that matches the required set of peripherals.

For microprocessors, the second step configures the GPIOs, performs the clock setup for the whole system, and interactively assigns the peripherals either to the Arm^® Cortex^®-M or to the Cortex^®-A world. Specific utilities, such as DDR configuration and tuning, make it easy to get started with STM32 microprocessors. For the Cortex^®-M core, the configuration includes additional steps that are identical to those described for microcontrollers.

For microcontrollers and microprocessor based on the Arm^® Cortex^®-M core, the second step consists in configuring each required embedded software thanks to a pinout-conflict solver, a clock-tree setting helper, a power-consumption calculator, and a utility that configures the peripherals (such as GPIO or USART) and the middleware stacks (such as USB or TCP/IP).

Eventually the user launches the generation that matches the selected configuration choices. This step generates the C initialization code for the Arm^® Cortex^®-M core, ready to be used within several development environments, or a partial Linux^® device tree for the Arm^® Cortex^®-A.
