Echo Driver Configuration
11.2 Separate Parameters for Each Bank
11.2.1 Bank Select
ECHO_BANK_A_EN, ECHO_BANK_B_EN
Description: This defines which bank is used: bank A, bank B, or both. If you use only one bank, bank A
is recommended.
Values:
0 = Bank is disabled
1 = Bank is enabled
#define ECHO_BANK_A_EN
1
Example:
11.2.2 Modulation Parameters
ECHO_MODE_VALUE
Description: This defines the RF modulation type used. On/off keying (OOK) or frequency shift keying
(FSK).
Values:
ECHO_OOK OOK modulation
ECHO_FSK FSK modulation
#define ECHO_MODE_VALUE ECHO_FSK
Example:
ECHO_MODE_OOKREF
Description: This defines the value of the OOKREF bit in Echo’s CONFIG2 register. OOKREF
controls the data slicer reference.
Values:
0 = fixed reference
1 = adaptive reference
#define ECHO_MODE_OOKREF 1 /* Select the data slicer reference */
Example:
ECHO_BAND_VALUE
Description: Selects the frequency band that Echo transmits and receives in.
Values:
ECHO_F 304MHz 304 MHz band
ECHO_F 315MHz 315 MHz band
ECHO_F 434MHz 434 MHz band
ECHO_F 868MHz 868 MHz band
ECHO_F 916MHz 916 MHz band
#define ECHO_BAND_VALUE ECHO_F434MHz
