C
void RTC_Timer32CompareSet ( uint32_t compare )
Summary
Set the 32-bit timer period value.
Description
This function sets the 32-bit timer compare value. The counter value will be compared against the compare value and a compare match event will occur when the counter matches the compare value. If the library is configured for interrupt mode and if a event handler function has been set through the RTC_Timer32CallbackRegister() function, the event handling function will be called. When the match occurs, the counter can optionally be reset if clear on compare is enabled to generate periodic interrupt.
Precondition
RTC_Initialize must have been called for the associated RTC instance. The RTC peripheral should have been configured in 32-bit Timer Counter mode.
Parameters
Param | Description |
---|---|
compare | Compare value |
Returns
None.
Example
uint32_t period = 0x00000FFF; RTC_Initialize(); RTC_Timer32CompareSet(period); RTC_Timer32CounterSet(0); RTC_Timer32Start(); while(!RTC_Timer32CompareHasMatched());
Remarks
This API is available for devices that have only one compare register in 32-bit mode. The RTC_Timer32Start() should typically be called after the period has been set.
