OS Design

[abhoan]

I need to create an RTOS for guidance system for a small automated aircraft model. Can it be made in C and can anyone guide me how to actually design it. I dont need any major fancy controls just X and Y axis controls output from the main processor. Iwas thinking of using an motorolla mobile class processor

Well, if you were able to provide us with a chipset for instructions or something we could be more of a service. I am sure many of us specialize in the X86 arc, and I am not sure what this processor is. You will most likely have to get a compiler from the company and instructions of how to dev from them. Sorry.

But at least for a great number of cpus there is a C compiler of some sort existing, so it would not be impossible.

Well, i can't name the chipset right now cause i don't have the exact idea which one to use. But i have some limitations like i can't use too much space for the whole hardware becuase of lack of space so there can be no major cooling. Also power avaliable will be throug battery and not a stable A.C source of 110 or 220 V.

No major computing power is required, only a basic time based pre-programmed C program has to be run to give ON and OFF output signals to the other hardware, ie motors.

I'll put up the exact requirements and project data in a week or so.. so you can cheak it out then..

Well if you have any ideas.. put them up..

Thanks

You don't need an OS for something this simple, just get a PIC microcontroller from a place like jameco.com
They run at up to 40mhz, some have C compilers from GNU I think, they have built in direct I/O, etc. It's basically a computer on a chip, program data, ram, and all.

Plus they run off a 9 volt battery if you regulate it down to 3.3v (I think).
