ChibiOS/RT is a free and efficient RTOS designed for deeply embedded applications. It offers a comprehensive set of kernel primitives and supports many architectures: ARM7, Cortex-M0, Cortex-M3, Cortex-M4, PowerPC e200z, STM8, AVR, MSP430, ColdFire, H8S, x86.
- Tiny memory footprint, high performance, easily portable, clean and readable.
- Preemptive kernel, 128 priority levels, reliable static architecture.
- Kernel support for Semaphores, Mutexes, CondVars, Messages, Event Flags, Mailboxes, Virtual Timers.
- IRQ abstraction, support for non-OS fast IRQ sources (zero latency buzzword).
- Support for ARM, ARM-CM0, ARM-CM3, ARM-CM4, PowerPC, STM8, MSP430, AVR, ColdFire, H8S, Linux/Win32/MacOS simulators.
- HAL component makes applications portable across the supported platforms.
- HAL support for Port, Serial, ADC, CAN, EXT, GPT, I2C, ICU, MAC, MMC, PWM, RTC, SDC, SPI, UART, USB device driver models.
- Support for the uIP and lwIP TCP/IP stacks (demo included).
- Support for the FatFS file system library (demo included).
Excellent design, elegant and nimble. It is well structured.
Great project! Quality code, does the job and WORKS! Long live Giovanni!
Thanks for so usefull software.
This is most advanced piece of open software I've ever used
thanks for this great software. it saves me so much time.
