    [SOLVED] RTOS and File Systems

    You can use any free RTOS even it doesn't include FS system. Take FatFS, for example, from http://elm-chan.org/fsw/ff/00index_e.html. If you want to have another (not FAT) FS, I think there are some in WEB there.

    [SOLVED] RTOS and File Systems

    Hello! Try to find any book that describe one of well known RTOS. It maybe something like ucOS-II, FreeRTOS, ThreadX, QNX... Oh, you also need FS... Then, read about QNX, ucOS,... More, all depends on your requirements.

    [SOLVED] how to cheaply drive high side of H bridge ?

    Something like this **broken link removed** But you should to protect the gates of the upper MOSFETS - to avoid +24V on the gates. For example, you can use a zener 15V1, 12V and so on. Good luck!
