Does it possible to emulate HW platform that is supported by freeRTOS and then run and test freeRTOS capabilities on that emulated hardware?  Is there any simulator for windows or linux that is capable such thing. Thanks. ---

The real simulators simulate the hardware itself, so you run a real port of FreeRTOS on them.  The Windows/Linux simulators run the FreeRTOS scheduler to schedule tasks, where the tasks are Windows/linux threads.  That means the kernel selects which task to run, but the context switching is done by WindowsLinux so it is not a real hardware port.

But it didnt work so I dont care I use VS to run it. I would like to learn more about this freertos even though I cant develop in C or C++, but I understand c code enough to learn something new. If there is anything please post  a link. thanks. bye
