9.3 Receiving FSK Data

Call adiStartReceivingFSK to enable an application to receive FSK data. While running, the FSK receiver is in one of the following four states: Idle Receiving Channel Seizure Receiving Mark Receiving Data
A complete packet of FSK data consists of either of the following sequences: Receive Channel Seizure, Receive Mark, Receive Data Receive Mark, Receive Data
During the receive operation, a number of errors may occur. These errors will cause the function to terminate prematurely. If errors occur, the ADIEVN_FSK_RECEIVE_DONE event is sent with one of the following reasons: ADI_REASON_DROP_IN_DATA - Stopped because of a drop in data. The noseizureflag signal dropped to silence during data, not during stop mark period. ADI_REASON_BAD_STOP_BIT - Stopped because of data framing error; the stop bit at the end of data was a space, not a mark.

9.3.1 Parameters for Receiving FSK Data

adiStartReceivingFSK requires four parameters defined in the ADI_FSKRECEIVE_PARMS structure:

minlevel - Required minimum receive level.

minmark - Minimum required initial mark and seizure time, in milliseconds.

mindrop - Minimum dropout to silence before a packet is considered terminated, in milliseconds.

baudrate - Transmission baud rate.
