Is there a way to change at run-time the rtos tick ? I know of course you can change a task frequency, but I have a high frequency application which requires also to sweep a frequency. In order to have more precision between steps, without at compile time increase the configTICKRATEHZ too much.
No dynamic tick frequency changing really because blocked tasks have a stored wake time, and changing the time base will result in them waking at the wrong time, but you can do tricks like halve the tick frequency then call the RTOS increment tick function twice per tick.
« then call the RTOS increment tick function twice per tick...»
Do you talk about the vTaskStepTick( TickType_t xTicksToJump ) function or another api call ?
The function that increments the tick is called xTaskIncrementTick (). The step tick function you refer to is only used in tickless idle mode.
