Function Documentation

void BEEP_Cmd ( FunctionalState NewState )

Enable or disable the BEEP function.

Parameters:

NewState Indicates the new state of the BEEP function.

Return values:

None

Required preconditions:: Initialisation of BEEP and LS RC calibration must be done before.

Definition at line 91 of file stm8s_beep.c.

void BEEP_DeInit ( void )

Deinitializes the BEEP peripheral registers to their default reset values.

Parameters:

None

Return values:

None

Definition at line 54 of file stm8s_beep.c.

void BEEP_Init ( BEEP_Frequency_TypeDef BEEP_Frequency )

Initializes the BEEP function according to the specified parameters.

Parameters:

BEEP_Frequency Frequency selection. can be one of the values of BEEP_Frequency_TypeDef.

Return values:

None

Required preconditions:: The LS RC calibration must be performed before calling this function.

Definition at line 67 of file stm8s_beep.c.

void BEEP_LSICalibrationConfig ( uint32_t LSIFreqHz )

Update CSR register with the measured LSI frequency.

Note on the APR calculation:: A is the integer part of LSIFreqkHz/4 and x the decimal part. x <= A/(1+2A) is equivalent to A >= x(1+2A) and also to 4A >= 4x(1+2A) [F1] but we know that A + x = LSIFreqkHz/4 ==> 4x = LSIFreqkHz-4A so [F1] can be written : 4A >= (LSIFreqkHz-4A)(1+2A)

Parameters:

LSIFreqHz Low Speed RC frequency measured by timer (in Hz).

Return values:

None

Required preconditions:
