DSP6951

Arduino Library for DSP6951 DSP Radio IC.

Supported devices

Known issue

  • Tuning to AM doesn't work.

Getting started

Circuit

circuit

(resistor is all 10k)

According to datasheet, the rated voltage is 3.3v.

However in my environment, it didn't work with 3.3v.

So I powers it with 5v and it worked successfully. (Also maximun voltage is 5.8v, so it is OK for the moment)

Sketch

#include <DSP6951.h>

DSP6951 radio;

void setup() {
  Serial.begin(9600);
  radio.begin();
  radio.setVolume(50);
  radio.setMode(DSP6951::FM);
  radio.setChannel(81.3);
}

void loop() {
  Serial.println(radio.getCNR()); //get "Carrier to noise ratio" and print it
  delay(300);
}

API Reference

  • void begin(void);

Initialize IC and prepare to work.

  • void setVolume(uint8_t volume);

Set output volume to the specified value(0-100).

  • void setChannel(float freq);

Set channel to the specified frequency.

  • void setMode(bool mode);

Set working mode (DSP6951::AM or DSP6951::FM)

Currently only FM is supported. AM support will be added soon.

  • void setMute(bool mute);

Set mute or not. Set true to mute, false to unmute.

  • uint8_t getCNR();

Get CNR(Carrier to noise ratio).

  • uint8_t getRSSI();

Get RSSI(Received Signal Strength Indication).

  • bool isTuned();

Get whether it is successfully tuned to the channel or not.

  • uint8_t getVolume();

Get current volume value. (0-100)

  • float getChannel();

Get current frequency.

  • bool getMode();

Get current working mode. (DSP6951::AM or DSP6951::FM)

  • bool getMute();

Get current mute state.

  • void tune();

Tune to current frequency expressly.

It doesn't needed in usual.
