RTOS for small embedded system.
TNKernal is the RTOS (real time operating system)
that was developed by Yuri Tiomkin (Russian).
The distinctive point of this RTOS is its APIs
that similar to µITRON 4.0 (Japanese RTOS developed
by Prof.Ken Sagamura).TNKernal can be ported to various
kind of micro controller such as Microchip PIC24/dsPIC,
ARM Cortex-M3,ARM LPC21xx/22xx,Freescale Coldfire,etc.
It also compatible with many Toolchanins from the free one
(Such as GNU Toolchanins) unto the expensive commercial
Toolchains.The current version of TNKernal is 2.5 and you
can download it at here or visit its website here.
TNKernal is open source and it is FREE!!!.
I think this RTOS was suitable for the small series
micro controller especially ARM and PIC.So if you’re looking
for the small RTOS that flexible for every small embedded
task and has complete basis mechanism of ordinarily RTOS,
TNKernal is your choice.
Salvo RTOS is RTOS suitable for low performance and low cost
embedded system because it requires little
program and data memory, without task stacks.
It was written in C.It support various kind of micro controller
(look for the supported micro controller here).Salvo is not
free but it has a demo version to download.It supported
many kinds of compilers (depend on the platform).It’s
not only can use on embedded platform but also x86 platform
(Using MS Visual C++ as compiler).In my opinion I think
Salvo is easy to use.It hide the complicate structure of
RTOS mechanism and provide you the easy to understand interface
that you can use for build your project (So you can emphasis on
your project without worry about the RTOS structure).
The current version of Salvo RTOS is 4 and you can find more information about it here.
