# 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
(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.
