Dependents:   IGGE_Power ADS1015-hello_world ADS1115-hello_world frdm_rtos_Eth ... more

Use like this

#include "mbed.h"
#include "Adafruit_ADS1015.h"
#include "USBSerial.h"

#define SERIAL_BAUD_RATE    9600

I2C i2c(p23, p18);
Adafruit_ADS1015 ads(&i2c);
USBSerial pc; // USB CDC serial port

 
int main() {
    uint16_t reading;
    while (1) {
        reading = ads.readADC_SingleEnded(0); // read channel 0
        pc.printf("reading: %d\r\n", reading); // print reading    
        wait(2); // loop 2 sek
    }
}

Library ported from Arduino at github repository.
