====== I2C communication with an Analog-to-Digital Converter : ADS1015 component ======

**This is an example of I2C communication with an ADC component.**

===== - Schematics =====
{{:products:flipper:schema_ads1015.png?|}}

For this example we used [[https://github.com/sparkfun/SparkFun_ADS1015_Arduino_Library|Sparkfun's ADS1015 Library]].

We are using the I2C1 communication bus so we will use Wire1 instance (if we were using I2C0 it would have been Wire instance, see [[products:flipper:arduino_bus_references|flipper arduino bus references]] ).\\
The i2C address of the ADS1015 is 0x48 since we connected ADDR pin to GND (see  {{ :products:flipper:ads1015.pdf |datasheet}} ) .

===== - Arduino Code =====
<file cpp flipper_ADS1015.ino>
#include 
#include 

ADS1015 adcSensor;

void setup() {
  Wire1.begin();
  Serial.begin(9600);
  if (adcSensor.begin(0x48, Wire1) == true) // connect to device at address 0x48
  {
    Serial.println("Device found. I2C connections are good.");
  }
  else
  {
    while(1) {
      Serial.println("Device not found. Check wiring.");
    }
  }
}

void loop() {
  uint16_t channel_A0 = adcSensor.getSingleEnded(0);
  Serial.print("A0:");
  Serial.println(channel_A0);
  delay(50); // avoid bogging up serial monitor²
}
