Parameters

Name Description
index int
The index of the pin to read.

Return

The analog voltage value between 0 and 1023 where 0 equals 0 volts and 1023 is the highest possible voltage value for the device.

Remarks

The pin value must be between 1 and 7. A return value of 0 equals 0 volts. A return value of 1023 equals the devices highest possible voltage.

Examples


function readAdc() {
	if (!KioGPIOBoard.isOpen()) return;
	var adcInd = document.getElementById('adcInd');
	var readRes = document.getElementById('readRes');
	var voltInt = KioGPIOBoard.readVoltage(parseInt(adcInd.value));
	var voltage = 3.3 * voltInt / 1023;
	readRes.innerHTML = voltage + 'V';
}

Requirements

KioWare for Android version 3.22 or greater.
