Get recogniser and interpreter working together

[mateiBanu]

Example main(sends a string back and forth):

#include "MicroBit.h"
#include "MicroBitAudioProcessor.h"
#include "StreamNormalizer.h"
#include "StreamSplitter.h"
#include "MicroBitMorseInterpreter.h"
#include "MicroBitMorsePlayer.h"

MicroBitAudioProcessor *fft = NULL;
MicroBitMorseCodeRecogniser *recogniser = NULL;
MicroBitMorseInterpreter *interpreter = NULL;

MicroBit uBit;

#define FREQUENCY 2200
#define TIME_UNIT 186

void onMessage(ManagedString message){
interpreter->stopInterpreting();
uBit.display.scroll(message);
interpreter->startInterpreting(onMessage);
}

void sendMessage(MicroBitEvent){
interpreter->stopInterpreting();
char in[] = "MORSE";
MicroBitMorsePlayer mp = MicroBitMorsePlayer(uBit, FREQUENCY, TIME_UNIT);
mp.play(in);
interpreter->startInterpreting(onMessage);
}

void interpret_test(){

NRF52ADCChannel *mic = uBit.adc.getChannel(uBit.io.microphone);
mic->setGain(7,0);
uBit.io.runmic.setDigitalValue(1);
uBit.io.runmic.setHighDrive(true);

StreamNormalizer *processor = new StreamNormalizer(mic->output, 1.2f, true, DATASTREAM_FORMAT_8BIT_SIGNED, 10);
StreamSplitter *splitter = new StreamSplitter(processor->output);
fft         = new MicroBitAudioProcessor(*splitter, MORSE_AUDIO_SAMPLES_NUMBER);
recogniser  = new MicroBitMorseCodeRecogniser(*fft, uBit, FREQUENCY, TIME_UNIT);
interpreter = new MicroBitMorseInterpreter(*recogniser, uBit);
interpreter->startInterpreting(onMessage);

uBit.messageBus.listen(DEVICE_ID_BUTTON_A, DEVICE_BUTTON_EVT_CLICK, sendMessage);

while(1){
    uBit.display.print(" ");
    uBit.sleep(500);
}

}

int
main()
{

uBit.init();
interpret_test();

}
