Common Usage

Here's the Raspberry Pi wired to the ADS1015 with I2C:

This example read all ports voltages.

const ads1x15 = require('ads1x15');

const main = async () => {
  const adc = new ads1x15();

  // open i2c bus. 0 for /dev/i2c-0 and 1 for /dev/i2c-1
  await adc.openBus(1);

  // Reading in Single shot mode channels 0-3
  console.log('Reading Single shot:');
  for await (let channel of [0, 1, 2, 3]) {
    const measure = await adc.readSingleEnded({channel});
    console.log(`Channel ${channel}: ${measure / 1e3} (V) Volts, ${measure} (mV) mili Volts`);
  }
}

main()
