Software

STM32 family of 32-bit Arm® Cortex® core-based microcontrollers and microprocessors are supported by a comprehensive set of software tools.

Traditional integrated development environments (IDEs) with C/C++ compilers and debuggers from major 3rd-party suppliers (free versions with up to 64 Kbytes of code are available) as well as the embedded software libraries required to configure and initialize the MCU or MPU and monitor its behavior in run time.

STM32CubeMX is a graphical tool used to configure any STM32 device. This easy-to-use graphical user interface generates the initialization C-code for Cortex-M cores and generates the Linux Device Tree for Cortex-A cores.

STM-STUDIO and STM32CubeMonitor-Power are monitoring tools that help developers fine-tune the behavior of their applications at run time.

An all-in-one multi-OS software tool, STM32CubeProgrammer provides an easy-to-use and efficient environment for reading, writing and verifying device memory through both the debug interface (JTAG and SWD) and the bootloader interface (UART and USB).

Enhanced STM32Cube tools simplify setting up MPU and MCU projects and configuring the on-chip resources. They accelerate the development of microcontroller- and microprocessor-based projects.

The software SDK and the specific audio algorithms developed for PA192 are available under license from FAE Technology.
