First of all, should i call the function in the main function, like after the vTaskStartScheduler? Secondly, what then do I have to do to see the tabular format ? Because from [https://www.freertos.org/rtos-run-time-stats.html](https://www.freertos.org/rtos-run-time-stats.html) , it looks like on the example picture one has to put in an ip addresss or so. ---

No - nothing that appears vTaskStartScheduler() will ever be reached s(assuming vTaskStartScheduler() actually starts the scheduler - which will be the case unless you run out of heap when creating the idle and/or timer tasks) so it won’t execute if you put it there. It should be called from whichever task you want to print the stats. > Secondly, what then do I have to do to see the tabular format ? Because from [FreeRTOS Run Time Stats](https://www.freertos.org/rtos-run-time-stats.html) , it looks like on the example picture one has to put in an ip addresss or so. The page you link to shows how to use run-time stats in general, including how to set up the clocks. The API page for vTaskGetRunTimeStats() is here [RTOS task (thread) utilities including API functions for tracing FreeRTOS, getting the RTOS tick count, getting a task handle, getting the RTOS kernel or RTOS scheduler state, listing the tasks in the embedded system, and obtaining run time task statistics.](https://www.freertos.org/a00021.html#vTaskGetRunTimeStats) and shows you pass in the address of the buffer into which you would like the stats to be written. That pages also shows the prerequisites of having configGENERATE\_RUN\_TIME\_STATS and configUSE\_STATS\_FORMATTING\_FUNCTIONS defined. ---
