<h3><b>Details:</b></h3>
<p>
Reads adc on input message True and cycle<br>
and stores in number array variable.<br>
Channel number is equal array index.<br>
Disabled channels are undefined in array.<br>
Enable channel with <b>Enable</b>.<br>
To get adc raw data select <b>Raw Data</b>.<br>
The output value is mV or adc raw data.<br>
Input voltages to ground<br>
gets only positive value.<br>
This node works on Raspberry Pi<br>
with 32bit or 64bit OS.<br>
Enable I2C with raspi-config.<br>
If you use i2c-0 port add<br>
<b>dtparam=i2c_vc=on</b> to /boot/config.txt<br>
i2c-0 port Pin27=SDA, Pin28=SCK<br>
For other ports add this to<br>
/boot/config.txt.<br>
I2C address connect ADDR pin:<br>
48H: GND or open.<br>
49H: VCC<br>
4AH: SDA<br>
4BH: SCL<br>
