# DSP6951

Arduino Library for DSP6951 DSP Radio IC.

## Supported devices

- [DSP6951](http://www.aitendo.com/product/7350)

- [M6951 module](http://www.aitendo.com/product/7011)

## Known issue

- Tuning to AM doesn't work.

## Getting started

### Circuit

![circuit](http://blog.y-modify.org/wp-content/uploads/2017/02/m6951-1.png)

(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

```cpp

#include 

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.
