Function Documentation

◆ EwBspClockCpuLoadSetActive()

void EwBspClockCpuLoadSetActive ( void  )

Starts the CPU load counting. Call this function whenever CPU processing is needed.

◆ EwBspClockCpuLoadSetIdle()

void EwBspClockCpuLoadSetIdle ( void  )

Stops the CPU load counting. Call this function whenever CPU processing is currently not needed since the program execution is waiting for some system event.

◆ EwBspClockGetCpuLoad()

int EwBspClockGetCpuLoad ( void  )

Returns the current CPU load as percent value.

Returns
int - The current CPU load.

◆ EwBspClockGetTicks()

unsigned long EwBspClockGetTicks ( void  )

The function EwBspClockGetTicks returns the current ticks counter value.

Returns
unsigned long - The current ticks counter value.

References EmWiSystemTicks.

Here is the caller graph for this function:

◆ EwBspClockGetTime()

unsigned long EwBspClockGetTime ( void  )

Returns the current time in seconds since 01.01.1970.

Returns
unsigned long - The current time in seconds since 01.01.1970.

References DaysToMonth, DaysToMonthInLeapYear, RtcHandle, RtcTicksPerDay, RtcTicksPerHour, and RtcTicksPerMinute.

Here is the caller graph for this function:

◆ EwBspClockInit()

void EwBspClockInit ( void  )

Initialises the system clock and the real time clock.

References EmWiSystemTicks, RTC_ASYNCH_PREDIV, RTC_SYNCH_PREDIV, RtcHandle, and SystemCoreClock.

Here is the caller graph for this function:

◆ EwBspClockSetTime()

void EwBspClockSetTime ( unsigned long  aTime)

Sets the given time in seconds since 01.01.1970 at real time clock (RTC).

Parameters
aTimeaTime - the time in seconds since 01.01.1970 to set in real time clock.

References RtcHandle, XTAL_Day, XTAL_Hour, XTAL_Min, XTAL_Month, XTAL_Sec, and XTAL_Year.

Here is the caller graph for this function:

◆ EwBspClockTickIncrement()

void EwBspClockTickIncrement ( void  )

The function EwBspClockTickIncrement increments the millisecond counter, which is used by the Runtime Environment (RTE) to trigger timer events.

References EmWiSystemTicks.

Here is the caller graph for this function:

◆ HAL_RTC_MspDeInit()

void HAL_RTC_MspDeInit ( RTC_HandleTypeDef *  hrtc)

RTC MSP De-Initialization This function frees the hardware resources used in this example:

  • Disable the Peripheral's clock
    Parameters
    hrtcRTC handle pointer
    Return values
    None

◆ HAL_RTC_MspInit()

void HAL_RTC_MspInit ( RTC_HandleTypeDef *  hrtc)

RTC MSP Initialization This function configures the hardware resources used in this example.

Parameters
hrtcRTC handle pointer
Note
Care must be taken when HAL_RCCEx_PeriphCLKConfig() is used to select the RTC clock source; in this case the Backup domain will be reset in order to modify the RTC Clock source, as consequence RTC registers (including the backup registers) and RCC_BDCR register are set to their reset values.
Return values
None
