How to start embedded RTOS & Device driver..?

[vinothksr08]

hai

i would like to study RTOS For an embedded system.. could you expalin how to combine RTOS & Embedded controllers??

 

[rajrahul2391]

for RTOS u hv to learn about operating systems i.e LINUX operating system.so learn linux .

 

[Vengateswaran]

First u have to learn the OS concepts and then API's for programming the RTOS.

I am also interested in RTOS programming and have experience in programming 8 bit and PIC 18 series and am beginner in PIC32 .
I would like to know where should i start .I have fair enough idea of linux terminal commandline .

Please give some idea , i downloaded free rtos but couldnt figure out how to install it , I use MPLAB and mikroc compilers how can i embed the rtos code in it .

 

[Vengateswaran]

RTOS code will be fully based on API's.. Linux terminal command line won't help in programming.. Only Rtos internals will be sumwat similar to linux.. So, u hav to learn list of API's and its usage..

I will express my view here -

First of all before going to RTOS please try to write the ISR ( interrupt service routine ) of micro-controller with multiple interrupt logic.....like deep say he want to do RTOS programming for PIC18F series....As I know PIC18F comes with low priority and high priority interrupts..... so first create the ISR with such multiple Interrupts.... one u get that you will start feeling need to handling the interrupts in real time and based on application need.... then my suggestion here is go for some FreeRTOS tutorials that will give you an idea how to use RTOS for the processor family that you want to use......

@ rajrahul2391 - It is not necessary to have linux known to work on RTOS porting on Micro-controller.....However it helps a bit.....but Linux is not an RTOS....it is a general purpose os..... there is a version of Linux comes called as RT-Linux ( Real Time Linux) which is RTOS.....

Any ways.....

Good Luck Guys

thanks for this valuable information sir,
where should i start learning RTOS, plz show me the way.......the whole procedure?

thanks u sir

Hi Rahul ,

I had given one side ( practical experience by which I had learn porting Rtos) an explanation about learning Rtos in my previous post ...... Now to learn Rtos formally I think best that you have to start with text book and then tutorial available on net.....also in case of free Rtos there are some example code even comes with package.... I think that you can also use as a starting point but be careful with that you need to know bit of Tool chain there.....

Good luck
