Maximum FreeRTOS Tick period

Posted by npatel on December 29, 2016

I am using FreeRTOS with the microblaze port and I am wondering how fast can I run the tick period. What is a typical RTOS tick period that FreeRTOS would work reliably with?

Thanks in advance.

Maximum FreeRTOS Tick period

Posted by rtel on December 29, 2016

The demo applications we provide typically have the tick frequency set to 1KHz (1ms) - but that is done to deliberately load and test the kernel and is faster than most applications need. 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 pdMSTOTICKS() macros will not work.
