The STM32Fx family modem configuration

parameter description

The following is a description of the modem configuration data struct:

typedef struct{

u32 m_Ser_H_Freq;

/* Frequency H Channel */

u32 m_Ser_L_Freq;

/* Frequency L Channel */

u8 m_Rx_Control;

/* RX Control Parameters */

u8 m_SerGain;

/* Gain*/

u16 m_SerZeroCrossing;

/*Zero Crossing*/

SV_PRE_LEN m_SerPSKPreamLen;

/*PSK Preamble Length*/

u8 m_FSK_Config_Byte

/* FSK Configuration Byte */

}MOD_ConfigTypedef;

The valid value of the parameters are:

m_Ser_H_Freq;

CENELEC A-B or C, compliant frequency integer value.

m_SerL_Freq;

CENELEC A-B or C, compliant frequency integer value.

m_ m_Rx_Control;

Rx Control byte value (see datasheet).

m_SerGain;

integer value from 0 to 31.

m_SerZeroCrossing;

Zero Crossing delay value.

m_SerPSKPreamLen;

BIT_16, BIT_24, BIT_32,BIT_40.

m_FSK_Config_Byte;

FSK Configuration Byte, (see datasheet).
