Function Documentation

getBass()

bool RDA5807::getBass ( )

inline

Gets Bass Boost.

Returns

FALSE = Disable; TRUE = Enable

getMute()

bool RDA5807::getMute ( )

inline

Gets Audio Mute Status. Same isMuted.

Returns

True if muted

getVolume()

uint8_t RDA5807::getVolume

(

)

Gets the current audio volume level.

Returns

uint8_t 0 to 15

isAudioOutputHighImpedance()

bool RDA5807::isAudioOutputHighImpedance ( )

inline

Gets true if the output audio impedance is high.

Returns

True or false

isMuted()

bool RDA5807::isMuted ( )

inline

Gets Audio Mute Status.

Returns

True if muted

isSoftmuted()

bool RDA5807::isSoftmuted ( )

inline

Gets the softmute status.

Returns

true if enabled

isStereo()

bool RDA5807::isStereo

(

)

Gets the current Stereo status.

Returns

TRUE if stereo;

setAudioOutputHighImpedance()

void RDA5807::setAudioOutputHighImpedance

(

bool

value

)

Sets audio output impedance high ow low.

Useful to setup high impedance headphones

Parameters

value

TRUE = High; FALSE = Low

setBass()

void RDA5807::setBass

(

bool

value

)

Sets Bass Boost.

Parameters

value

FALSE = Disable; TRUE = Enable

setLedStereoIndicator()

void RDA5807::setLedStereoIndicator ( bool  value = true )

inline

Sets the system to use a LED to indicate Stereo or Mono.

Call this function to setup the GPIO3 of the RDA5807FP (pin 15) to turn a LED on or OFF.

When Stereo, the GPIO3 is HIGH.

#include <RDA5807.h>
RDA5807 rx;
void setup() {
   rx.setup();
   rx.setFrequency(10390); // Tunes in 103.9 MHz
   rx.setLedStereoIndicator(true); // The GPIO3 (pin 15 of the RDA5807) can use to turn a LED on when Stereo
}
void loop() {
}

Parameters

value

true or false.

  pinMode(4, INPUT_PULLUP); // Arduino pin 4 - Volume Up
  pinMode(5, INPUT_PULLUP); // Arduino pin 5 - Volume Down
  rx.setup();
  rx.setFrequency(10390); // Tunes at 103.9 MHz
  rx.setVolume(7);
}
void loop() {
  if (digitalRead(4) == LOW) rx.setVolumeUp();
  if (digitalRead(5) == LOW) rx.setVolumeDown();
  delay(200);
}
