2.2.1 STM32CubeMX
Figure 12. STM32CubeMX Configure and code generation
STM32CubeMX is a graphical tool that allows to easily configure STM32 microcontrollers
and to generate the corresponding initialization C code through a step-by-step process.
The first step consists in selecting the STM32 microcontroller that matches the required set
of peripherals. MCU can be selected as stand-alone for custom PCB (MCU Selector) or pre-
integrated into one of STMicroelectronics hardware kit (Board Selector)
In the second step, the user must configure each required embedded software thanks to a
pinout-conflict solver, a clock-tree setting helper, a power-consumption calculator, and a
utility performing MCU peripheral configuration (GPIO, USART, and others) and middleware
stacks (USB, TCP/IP, and others).
Finally, the user launches the generation of the initialization C code based on the selected
configuration. This code is ready to be used within several development environments. The
user code is kept at the next code generation.
