Typedefs

typedef void(* RTCDRV_Callback_t) (RTCDRV_TimerID_t id, void *user)
 Typedef for the user supplied callback function which is called when a timer elapse. More...
 
typedef uint32_t RTCDRV_TimerID_t
 Timer ID.
 

Enumerations

enum  RTCDRV_TimerType_t {
  rtcdrvTimerTypeOneshot =0,
  rtcdrvTimerTypePeriodic =1
}
 Timer type enumerator. More...
 

Functions

Ecode_t RTCDRV_AllocateTimer (RTCDRV_TimerID_t *id)
 Allocate timer. More...
 
Ecode_t RTCDRV_DeInit (void)
 Deinitialize RTCDRV driver. More...
 
Ecode_t RTCDRV_Delay (uint32_t ms)
 Millisecond delay function. More...
 
Ecode_t RTCDRV_FreeTimer (RTCDRV_TimerID_t id)
 Free timer. More...
 
uint32_t RTCDRV_GetWallClock (void)
 Get wallclock time. More...
 
uint32_t RTCDRV_GetWallClockTicks32 (void)

Ecode_t RTCDRV_StartTimer (RTCDRV_TimerID_t id, RTCDRV_TimerType_t type, uint32_t timeout, RTCDRV_Callback_t callback, void *user)
 Start a timer. More...
 
Ecode_t RTCDRV_StopTimer (RTCDRV_TimerID_t id)
