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

|
|
| uint64_t | RTCDRV_GetWallClockTicks64 (void) |
|
Get a wallclock tick count as a 64 bit value.
|
|
| Ecode_t | RTCDRV_Init (void) |
|
Initialize the RTCDRV driver.
|
|
| Ecode_t | RTCDRV_IsRunning ( RTCDRV_TimerID_t id, bool *isRunning) |
|
Check if a given timer is running.
|
|
| uint64_t | RTCDRV_MsecsToTicks (uint32_t ms) |
|

|
|
| uint64_t | RTCDRV_SecsToTicks (uint32_t secs) |
|
Convert from seconds to RTC/RTCC ticks.
|
|
| Ecode_t | RTCDRV_SetWallClock (uint32_t secs) |
|
Set wallclock time.
|
|
| Ecode_t | RTCDRV_StartTimer ( RTCDRV_TimerID_t id, RTCDRV_TimerType_t type, uint32_t timeout, RTCDRV_Callback_t callback, void *user) |
|
Start a timer.
|
|
| Ecode_t | RTCDRV_StopTimer ( RTCDRV_TimerID_t id) |
|
Stop a given timer.
|
|
| uint32_t | RTCDRV_TicksToMsec (uint64_t ticks) |
|
Convert from RTC/RTCC ticks to milliseconds.
|
|
| uint64_t | RTCDRV_TicksToMsec64 (uint64_t ticks) |
|
Convert from RTC/RTCC ticks to milliseconds with 64-bit resolution.
|
|
| uint32_t | RTCDRV_TicksToSec (uint64_t ticks) |
|
Convert from RTC/RTCC ticks to seconds.
|
|
| Ecode_t | RTCDRV_TimeRemaining ( RTCDRV_TimerID_t id, uint32_t *timeRemaining) |
|
Get time left before a given timer expires.
