WebAug 2, 2024 · FreeRTOS uses a user/application specific timer to measure the task execution time. For this, every task descriptor inside the RTOS has a cumulative counter which adds the timer ticks spent for that task.

WebAug 14, 2024 · Then a tick is not 1ms long, but 1.25ms or 2.5ms respectively, which is an integer multiple. Most OS'es have the systick rate as a configuration in a header file, or perhaps in the CMSIS library sometimes as well. You will probably still need an OS (software) timer to handle the task activation though.

WebHi, I've been in trouble with TTC interrupt task under FreeRTOS. My design uses only cpu0 of Zynq XC7000. After reading lots of application notes and googling about the Timer interrupt under FreeRTOS \+ Zynq environment, I found that FreeRTOS uses SCUTIMER for its task scheduling tick, so applications can't use the private timer of each … WebDec 16, 2014 · A faster tick rate does not make anything run faster, it simply increases the resolution of timers and delays that may be used, but conversely it reduces the range.
