What is a typical RTOS tick period that FreeRTOS would work reliably with? Thanks in advance. ---

It seems common for real applications to use a tick frequency of 100Hz, but the optimal frequency is of course dependent on the application. It is not normal to go above 1KHz, and if you think you need a faster tick frequency then perhaps you could look at using hardware timer interrupts instead. If you do go above 1KHz then note the pdMS\_TO\_TICKS() macros will not work.
