WebDec 31, 2024 · To operating system uses a counter to measure the task execution time. So at task context switching time this counter is used to determine the time used by that task. The important point is that this time is not absolute (e.g. 37ms) but just a number of ‘ticks’ (e.g. 241 ticks). The RTOS knows how many ‘ticks’ have been used overall.

WebMar 12, 2014 · rtel wrote on Wednesday, March 12, 2014:. There are several ways of doing this, but in each case you need to supply a fast clock as a time base. The fast clock needs to provide time at a rate many times higher than the tick count increment, otherwise you will not get the resolution you need. WebOct 31, 2024 · In its default configuration, FreeRTOS uses a scheduling policy where it will switch between tasks that are the same priority in round-robin order on each tick, and task execution happens within a time slice.

This means if these tasks get starved of execution time, then after a timeout period, the watchdog gets triggered and resets the chip. The IDLE tasks do some important FreeRTOS "household" work in the background, so you have to give them time.
