This function can be used for both full- and half-width modes of 16/32-bit timers and for half-width modes of 32/64-bit timers.
This function configures the timer load value if the timer is running then the value is immediately loaded into the timer. Only TIMER_A should be used when the timer is configured for full-width operation. UlTimer specifies the timer(s) to adjust must be one of TIMER_A, TIMER_B, or TIMER_BOTH.
UlBase is the base address of the timer module. TimerLoadSet(unsigned long ulBase, unsigned long ulTimer, unsigned long ulValue) (hopefully this function "did" survive into the newer API.) I submit, " TimerLoadSet()" - as excellent (and intended) to satisfy your requirement.įollows the detailed description of this function. (Note: my firm employs (only) past StellarisWare 9453 (which was believed to be "bullet-proof" - newer incarnations - "Not so much!") Perhaps this (answering) function - resident w/in StellarisWare - did not "pass thru" to your "newer" API. I believe so - yet due to your experience & savvy - it is troubling that you (appear) to have "missed" this. Is there a TivaWare function that accomplishes what I want? If so, TivaWare provides a function TimerValueGet() but does not provide a function TimerValueSet(). Is this the correct way to "restart" the timer back to the beginning?Ģ. My line of thought is to restart the timer (and therefore prevent triggering the interrupt) by loading the start value into GPTMTAV every time the event occurs.ġ. If the event does not occur, the timer "times out" and triggers the interrupt, which handles the lack of event. But I never allow that interrupt to trigger: Every time the event in question occurs, the event handler restarts the timer (sets its counter back to 0 or maximum depending on count direction). So for example if the event is expected to occur every 950 uS, I might configure a periodic timer to trigger an interrupt every 1 ms. The way I've always done this on other MCUs is to set up a Timer to generate a periodic interrupt. That is, in the absence of a certain event in a given length of time, the timer should trigger an interrupt. I am trying to use a General Purpose Timer peripheral to respond to a timeout condition.
