RTOS choice for PIC24/dsPIC

[lucicop]

Hi,

Do you know if they have released this ? Does any of you have it ? Thanks !

I see no one knows anything about this. On the Hi-Tech forums too it is the same silence. I guess this combination is not used. I think I will switch to MPLAB C30 compiler, and for that there are more options for an RTOS. I would like to discuss with you what you are using as an RTOS if you are using PIC24/dsPIC devices.

have a look to www.picos18.com they have an RTOS for PIC18 and a version for PIC24/dsPIC. and it's open sources with multiple drivers.

Hi, I use uC/OS-II with dsPIC33FJ256GP710 and MPLAB C30. I'm very satisfied. RTOS viewer from MPLAB supports this OS, but still better is uC/OS-View. With this property you will see,  what is happening in real time.

Thanks for the replies. I have formed my oppinion and I plan to use uCosII too, with C30 compiler. It is similar to Salvo in naming conventions and I like that. It is very different from Salvo in the fact that is preemptive, and so the applications will need to be redesigned in order to be ported.

Hi lucicop and jezo,

From where did downloaded ucOS-II for PIC18?

Thanks in advance for sharing,

uC/OS need work with stack (every one task has a self stack space). PIC18 hasn't real stack, only for storing calls. For this  processor you can try Salvo.

I plan to use uCos/II with PIC24, and it exists a uCos port for this processor. uCos has the source publicly available on www.micrium.com .

        Hello,

   there is also the TNKernel ( http://www.tnkernel.com/port_dsPIC.html ) which open source.

   extract from the website :

  "TNKernel performs a preemptive priority-based scheduling and a round-robin scheduling for the tasks with identical priority. The current version of TNKernel includes semaphores, mutexes, data queues, event flags and fixed-sized memory pools. The system functions calls in the interrupts are supported."

   the list of feature seem very comprehensive but i haven't use it.

   is everyone have already use it ?

you can try here: www.freertos.org

there is pic24/dsPic port.
