Alternatively, you can create another task that ticks at 1 Hz to increment a counter and use that as system time. To get an actual date however, you'll need to consult your development board and see if it has an RTC. WebJan 27, 2024 · Another point, you DON’T need a wait for 33 micro-seconds, but a wait to the next 100 micro-second period, so you just need a 10 kHz rate timer. In FreeRTOS, delays are always relative to the timer, so a delay of 1 tick means delay until the next tick interrupt, which might be almost no time. 10 kHz is a bit fast in my opinion for the ...

WebThe FreeRTOS Kernel uses Ticks to schedule and keep track of the various tasks in a microcontroller up to 1KHZ. Example. If your FreeRTOS is configured to use a frequency of 100HZ, your tick rate would be 10ms. If the task needs to be delayed by 500ms, the TickType_t would be 50 (500/10).
