embOS-Ultra Cortex-M GCC
embOS-Ultra RTOS port for development with GCC-based toolchains targeting Cortex-M based microcontrollers.
Board support packages (BSPs) for different Arm devices and evaluation boards are included.
Development environment
The embOS-Ultra Cortex-M GCC port is not tied to a specific IDE. It can be used with any GCC-based development environment supporting Cortex-M based devices. The following list includes examples for development tools based on GCC:
- Atmel Studio
- Atollic TrueSTUDIO
- CodeSourcery
- Cypres PSoC Creator
- emIDE
- GNU MCU Eclipse
- Makefiles + GDB or Ozone
- MCUXpresso IDE
- Renesas e2Studio
- STM32CubeIDE
