FreeRTOS是一个迷你操作系统内核的小型嵌入式系统。作为一个轻量级的操作系统,功能包括:任务管理、时间管理、信号量、消息队列、内存管理、记录功能等,可基本满足较小系统的需要。
FreeRTOS 7.0 改进内容:
1. 全新的软件定时器的实现
2. tasks.c 核心实现的一些增强
3. Calls were added to configASSERT() within the kernel code.
4. The MSP430X IAR port and demo project were updated to include support for the medium memory model.
5. Demo projects were added for the MSP430X and STM32 Discovery Boards.
6. Some compiler warnings were removed from the PSoC demo application.
7. The PIC24, dsPIC, and PIC32 projects were updated so they work with the latest MPLAB compiler versions from Microchip

FreeRTOS-A Free professional grade RTOS supporting 27 architectures, including ARM7, ARM9, Cortex-M3, RX600, MSP430, MSP430X, MicroBlaze, AVR, x86, PIC32, PIC24...
