I have been fiddeling with timers and trying to retrive the currently set period from a TimerHandle_t handle. So far my attempts have faied with compile errors.
Depending on the currently set period i want my callback function do do different things.
Is there an easy way to get the currently set period of a timer? Could perhaps a function for this be added in future versions?
You could store the current set period in a variable that is available to the task that wants to know. Alternatively you could store the timer's current set period in its ID, and then read the timer's ID to determine what the period was (note the V8.2.1 release had a discrepancy in how const was used between the prototype and implementation of the set id function).
See the example on the vTimerSetTimerID() documentation page:
I went for a variable keeping track of the last set period.
A function that accesses this from withing the timer would be nice.
