◆ getRdsProgramInformation()

char * BK108X::getRdsProgramInformation ( void )

inline

Gets the Program Information (RT - Radio Text)

@

Process the program information data. Same getRdsText2A(). It is a alias for getRdsText2A.

ATTENTION: You must call getRdsReady before calling this function.

Returns: char array with the program information (63 bytes)

See also: getRdsText2A

Definition at line 1158 of file BK108X.h.

References BK108X::getRdsText2A().

◆ getRdsStationInformation()

char * BK108X::getRdsStationInformation ( void )

inline

Gets the Station Information.

ATTENTION: You must call getRdsReady before calling this function.

Returns: char array with the Text of Station Information (33 bytes)

See also: getRdsReady

Definition at line 1167 of file BK108X.h.

References BK108X::getRdsText2B().

◆ getRdsStationName()

char * BK108X::getRdsStationName ( void )

inline

Gets the Station Name.

Alias for getRdsText0A

ATTENTION: You must call getRdsReady before calling this function.

Returns: char* should return a string with the station name. However, some stations send other kind of messages

References BK108X::getRdsText0A().

◆ setRdsMode()

void BK108X::setRdsMode ( uint8_t rds_mode = 0 )

Sets the Rds Mode Standard or Verbose.

There is no information about it in the BK1088 documentation.

Parameters

rds_mode 0 = Standard (default); 1 = Verbose

Definition at line 1091 of file BK108X.cpp.

◆ setRds()

void BK108X::setRds	(	bool	value,
		bool	interrupt_enable = `false`
	)

Sets the RDS operation.

Enable or Disable the RDS

You can setup interrupt via GPIO2. It is useful to avoid pulling during RDS queries.

When a new RDS data is available (new RDS information came) a 5ms low pulse will appear at GPIO2

Parameters

true	= turns the RDS ON; false = turns the RDS OFF
true	= enable interruot at GPIO2 when new RDS is available (default false).

Definition at line 1105 of file BK108X.cpp.

Referenced by BK108X::setRDS().

◆ getRdsReady()

bool BK108X::getRdsReady ( )

Returns true if RDS Ready.

Read addresses 0Ah, 0Ch, and check the bit RDSR.

If in verbose mode, the BLERA bits indicate how many errors were corrected in block A. If BLERA indicates 6 or more errors, the data in RDSA should be discarded.

When using the polling method, it is best not to poll continuously. The data will appear in intervals of ~88 ms and the RDSR indicator will be available for at least 40 ms, so a polling rate of 40 ms or less should be sufficient.

ATTENTION: You must call this function before calling any RDS function to process data

Returns: true or false

Returns: program type (an integer betwenn 0 and 31)

Definition at line 1184 of file BK108X.cpp.

◆ getNext2Block()

void BK108X::getNext2Block ( char * c )

inline

Process data received from group 2B - Station Name.

It appears that the BK1088 device is typically pre-configured with RBDS setup instead of RDS by default.

Consequently, the Station Name is obtained from block E instead of block B.

The documentation from BEKEN used in this project does not provide instructions on how to switch from RBDS to RDS mode.

If anyone has access to this information, kindly share it with us.

Parameters

c	char array reference to the "group 2B" text

◆ getNext4Block()

void BK108X::getNext4Block ( char * c )

inline

Processes data received from group 2A.

decodes data received from block C and block D

Parameters

c	char array reference to the "group 2A" text

◆ getRdsText()

char * BK108X::getRdsText ( void )

Gets the RDS Text when the message is of the Group Type 2 version A.

Returns: char* The string (char array) with the content (Text) received from group 2A

Definition at line 1227 of file BK108X.cpp.

◆ getRdsText0A()

char * BK108X::getRdsText0A ( void )

Gets the Station Name and other messages.

Todo:

Need to check Block B and Block E and RDS mode

RDS Dynamic PS or Scrolling PS support

Same getRdsStationName.

Returns: char* should return a string with the station name. However, some stations send other kind of messages

		char **	stationInformation,
		char **	programInformation,
		char **	utcTime
	)

Gets Station Name, Station Information, Program Information and utcTime.

This function populates four char pointer variable parameters with Station Name, Station Information, Programa Information and UTC time.

You must call setRDS(true), setRdsFifo(true) before calling getRdsAllData(...)

ATTENTION: the parameters below are point to point to array of char.

the right way to call this function is shown below.

char *stationName, *stationInfo, *programInfo, *rdsTime;
// The char pointers above will be populate by the call below. So, the char pointers need to be passed by reference (pointer to pointer).
if (rx.getRdsAllData(&stationName, &stationInfo , &programInfo, &rdsTime) ) {
    showProgramaInfo(programInfo);
    showStationName(stationName);
    showStationInfo(stationInfo);
    showUtcTime(rdsTime);
}

Parameters

stationName	(reference) - if NOT NULL, point to Name of the Station (char array - 9 bytes)
stationInformation	(reference) - if NOT NULL, point to Station information (char array - 33 bytes)
programInformation	(reference) - if NOT NULL, point to program information (char array - 65 nytes)
