STMicrolectronics or STMicrolectronics' partner packages can be downloaded directly from a dedicated package manager available within STM32CubeMX, while the other packages can be installed from a local drive. The default software and middleware stacks can be extended thanks to enhanced STM32Cube Expansion Packages. For microcontrollers and microprocessor Arm ® Cortex ®-M, 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 an utility that configures the peripherals (such as GPIO or USART) and the middleware stacks (such as USB or TCP/IP). For Cortex ®-M core, the configuration includes additional steps that are exactly similar to those described for microcontrollers. Specific utilities, such as DDR configuration and tuning, make it easy to get started with STM32 microprocessors. For microprocessors, the second step allows to configure the GPIOs and the clock setup for the whole system, and to interactively assign peripherals either to the Arm ® Cortex ®-M or to the Cortex ®-A world. The first step consists in selecting either an STMicrolectronics STM32 microcontroller, microprocessor or a development platform that matches the required set of peripherals, or an example running on a specific development platform.
