RTOS for an 8-bit microcontroller?

vandana

We are starting a new product that we know will grow into a 32-bit implementation down the road and will want to reuse the software on this project. Does anyone have experience with an RTOS in an 8-bit design (Microchip, TI or Freescale) that can make a recommendation?

    Hello,

     

    You seem to be mixing up a few different issues here.

    If you see the need to migrate to 32 bit why not start with a 32 bit micro - you can get ARM Cortex 3 parts from 50p. If you choose a part form a large family (eg ST, NXP or TI) the peripherals can stay the same up to quite powerful parts.

    You can re-use your code if you write it suitably with or without an RTOS.

    Before choosing an RTOS (or if to use one at all) you need to set out what you want it to do for you and don't forget that you will pay a price in performance (and time/money) for every feature.
