mcp3008.js
A node.js module for interfacing the MCP3008 analog/digital converter.
The same instance of the module can control all eight channels on the converter.
Installation
$ npm install mcp3008.js
Usage
Here's a short example:
var Mcp3008 = require('mcp3008.js'),
adc = new Mcp3008(),
channel = 0;
adc.read(channel, function (value) {
doSomethingToValue(value);
});
Interface
Constructor
new Mcp3008([device]);
Device defaults to /dev/spidev0.0.
Reading
instance.read(channel, callback);
This will read the value on channel and send it to callback.
Polling
instance.poll(channel, interval, callback);
This will read the value on channel every interval milliseconds and send it to callback. Use instance.stop(channel) to stop it.
Tear down
instance.close();
This will release the device and stop polling (if any).
