Interfacing External Sound Sensor with nRF52832

[g.joshi]

I have made following connection between nordic device and external sound sensor:

1. VCC--> 5V
2. GND--> GND
3. GATE --> Pin 04
4. ENVELOPE --> A0

I would like to know how to proceed with the code in eclipse. i have a code but i am not sure how to proceed with it.

Thanks in Advance

Hi,

First have a look at the following tutorial:

devzone.nordicsemi.com/.../

Maybe try something simple first, like a blinky application to make sure your toolchain is set up right.

Also, you should try to give us more information about the SDK version you wish to use. If you wish to use a softdevice and other relevant things about your application.

[g.joshi]

static void nrf_gpio_cfg_input(GATE, NRF_GPIO_PIN_NOPULL) static void nrf_gpio_pin_read(GATE

)

    void soundISR()
    {
      int pin_val;
    
      pin_val = digitalRead(PIN_GATE_IN);
      digitalWrite(PIN_LED_OUT, pin_val);
    }
    
    void setup()
    {
      Serial.begin(9600);
    
      //  Configure LED pin as output
      pinMode(PIN_LED_OUT, OUTPUT);
    
      // configure input to interrupt
      pinMode(PIN_GATE_IN, INPUT);
      attachInterrupt(IRQ_GATE_IN, soundISR, CHANGE);
    
      // Display status
      Serial.println("Initialized");
    }

Does this makes sense ??
