rtems could without doubt be worth a try but have only used FreeRTOS and it work.
FreerRTOS usually run scheduler at 1kHz and using one of the newer Micro controllers like Cortex-Mx which is a very common CPU in these with prioritized interrupts for higher priorities work really well. There is also support calling some of the functions from within interrupts but not all since they are not allowed to block. It might be this prioritized interrupt controller may make FreeRTOS work really well since then interrupts could be assigned a priority so that they are correctly scheduled and guess this is not the case on an ordinary computer. Guess NML would be a better choice for remote display. > FreeRTOS sure is popular.
