RT-Thread

An open source real-time operating system for embedded devices

RT-Thread 1.0.0 Released

RT-Thread is 5 years old now since it was first born in 2006. It has gone through several versions (0.2.x, 0.3.0, 0.3.3, 0.4.0 beta1, 0.4.0 beta2, 0.4.0 RC1) and gets the following points:

A more stable kernel:
The kernel has an enhanced check function in context switch, and more error detections.

Many enriched modules:
The RT-Thread now has filesystems, RTGUI, and support for TCP/IP stacks, dynamic loading modules, and POSIX. When using GCC, we can enable the newlib option, and support for the entire standard C runtime library.

Much more complete branches porting:
The RT-Thread is supporting 32-bit MCUs under the architectures of ARM7, ARM9, ARM Cortex-M3, ARM Cortex-M4, MIPS, AVR32, V850E, etc, and is also supporting the 16-bit Renesas M16C series.

We are so glad to release this RT-Thread 1.0.0 version. This official version can’t be finished without our developers’ hard working, and everyone who have helped this project!
Thanks to Heng Li to initiate the underline salone.
Thanks to the Shanghai Pudong Software Technologies Service Co.,Ltd to provide field for our subject salons.
Thanks to grissiom to translate documents of coding style, and patches for RTGUI
Thanks to onelife who maintains the EFM32 branch.
Thanks to everyone!
