STMicroelectronics STM32CMICOS-EVAL

Overview

STM32CMICOS-EVAL from STMicroelectronics is an evaluation package comprising a hardware board and a companion book, designed to demonstrate and teach the µC/OS-III real-time kernel on STM32F107 connectivity-line microcontrollers. It supports preemptive multitasking, unlimited tasks, semaphores with priority inheritance, event flags, message queues, kernel timers, and fixed-size memory block management.

For engineers reviewing the STM32CMICOS-EVAL datasheet, STM32CMICOS-EVAL pinout, STM32CMICOS-EVAL application, or STM32CMICOS-EVAL equivalent, this kit delivers hands-on validation of RTOS integration, task scheduling behavior, inter-task communication primitives, and memory management in embedded Cortex-M3 systems.

Technical Context

The STM32CMICOS-EVAL centers on the STM32F107VC microcontroller - a 72 MHz ARM Cortex-M3 device with USB OTG FS, Ethernet MAC, CAN, and multiple serial interfaces. It serves as a reference platform for porting and exercising µC/OS-III's core services including OSFlagPost(), OSQPost(), OSTmrCreate(), and OSMemCreate().

The included book provides line-by-line analysis of kernel source code and step-by-step walkthroughs of 14+ working examples, covering initialization, context switching, ISR interaction, and debugging techniques specific to the STM32F107 hardware abstraction layer.

FAQ

Is STM32CMICOS-EVAL still in production?

No - STM32CMICOS-EVAL is marked obsolete by STMicroelectronics as of its 2010 release. It remains available through authorized legacy distributors and Aetrix Electronics' extended-life inventory program for educational and maintenance use, with full documentation and example code preserved.

Does this kit include the µC/OS-III source code?

Yes - the STM32CMICOS-EVAL package includes a licensed copy of µC/OS-III source code tailored for the STM32F107, along with Keil MDK-ARM project files, startup assembly, linker scripts, and peripheral drivers required to build and debug all examples in the companion book.

Can I use this board with modern IDEs like STM32CubeIDE?

Yes - while originally configured for Keil µVision, the provided source code and HAL-compatible drivers can be imported into STM32CubeIDE. Users must reconfigure clock trees, debug probes, and linker sections; ST's AN3966 application note documents migration steps for µC/OS-III on STM32Cube.

What peripherals are accessible for RTOS demonstration?

The board exposes Ethernet MAC + external PHY, USB OTG FS, dual CAN channels, USARTs, SPI, I²C, and GPIOs - all integrated into µC/OS-III examples for concurrent driver testing, ISR nesting, and resource-sharing scenarios using semaphores and message queues.
