Hi,

When we use xTaskCreateStatic() instead of xTaskCreate() -

Are both task TCB and stack are created staticlly in the ram not in the RTOS heap section ?

Thank you

Michael

xTaskCreateStatic requires you to provide both a buffer for the TCB and for the Stack, and doesn’t use any of the Heap.

Can I use API xTaskCreateStatic() in my application or it is only for kernel use ?

A quick look at the documentation one will find: https://www.freertos.org/xTaskCreateStatic.html

A quick search of the source code on your computer will locate the reference code or macro for the function… if it’s not there, you are most likely running an old version of FreeRTOS.
