cat-haines / agent.nut

Last active December 20, 2015 23:58

Here's some code I wrote in my mail editor to demonstrate how you can use ping-pong messages to only respond to an HTTP request after receiving confirmation that your imp got the message. It also uses a watched function to return timeouts if a specific timeout is exceeded.

	responseQueue <- [];
	timeout <- 5; // timeout (in seconds) for roundtrip from agent -> device -> agent.

	// function that triggers responses if timeout expires
	function checkResponses() {
	local newQueue = [];
	// loop through http response queue
	local t = time();
	for (local i = 0; i < responseQueue.len(); i++) {
	// if it's been sitting for more than allowed timeout

cat-haines / agent.button.js

This GIST has four files and demonstrates how data can be passed from one imp to another using HTTP requests, and HTTP request handlers.

	const otherAgentUrl = "http://agent.electricimp.com/YourOtherAgentID";

	// create a handler for the "button" message from the device
	device.on("button", function(state) {
	local url = otherAgentUrl + "?led=" + state;
	server.log("sending request to " + url);
	// create the request
	local request = http.get(url);
	// send the request
	request.sendsync();

This is a collection of code snipper for the blog post at: beardedinventor.com/2013/06/12/Migrating-from-HTTP-Nodes-to-Agents/ These files are actually .nut files (Squirrel) - but we store them as .js for formatting and syntax highlighting.

	// Create a class to control an LED from an input port
	class LedController extends InputPort {

	led = null;

	constructor(name, _led) {
	base(name);
	this.led = _led;
	}

cat-haines / pulse.js

Last active December 16, 2015 20:19

A simple Squirrel class for handeling pulses as a type of digital input and a simple example using it. NOTE: Accuracy has NOT been tested.

	/*******************************************************************************
	* Reads a pulse (either HIGH or LOW) on a pin. If the pulseValue is HIGH,
	* the object will start timing when the pin goes HIGH, then waits for the pin
	* to go LOW, and executes the callback (callback expects a function with one
	* parameter, the length of the pulse in microseconds).
	*
	* The accuracy of this function has not been tested, and will have some
	* variance because of how callbacks work.
	******************************************************************************/
	class Pulse {

Electric Imp example API

	local greenState = 0;
	local redState = 0;

	device.on("setRed", function(data) {
	redState = data;
	});

	device.on("setGreen", function(data) {
	greenState = data;
	});

cat-haines / HttpRequestResponse.nut

Created April 19, 2013 21:10

Electric Imp example code that processes an incoming HTTP Request (through an HttpIn node hooked up to an InputPort) and sends a "response" (which is actually just an HTTP Post to a predefined location).

	// This is the function that actually handles the incoming HTTP Request
	function SimpleRequestHandler(data) {
	server.log("Got a request with value='" + data + "'");
	return 200;
	}

	// handles incoming HttpIn requests, and sends "responses" to an HttpRequest node through
	// an output port. The ResponsePort sends a url-encoded message where "value" is the response code.
	class HttpInPortWithResponse extends InputPort {
	RequestHandler = null; // function that will be called whenever a request comes into the input port. Should return a status code.

Electric Imp code for polling an analog input every half second.

	imp.configure("Analog In", [], []);

	function readPots()
	{
	local p = hardware.pin5.read();
	server.show(p);
	imp.wakeup(0.5, readPots);
	}

	hardware.pin5.configure(ANALOG_IN);

cat-haines / RGB Imp

Last active December 14, 2015 02:29

Electric Imp code to go with Electric_Imp_Example repository. Passes RGB json object to Electric_Imp_Example API.

	local redPot = hardware.pin5;
	local greenPot = hardware.pin7;
	local bluePot = hardware.pin8;

	local red = 0;
	local green = 0;
	local blue = 0;

	local redPort = OutputPort("red");
	local greenPort = OutputPort("green");

ElectricImp code for setting an LED based on value from an InputPort

	class simpleInputPort extends InputPort
	{
	function set(value)
	{
	if (value == 1)
	{
	server.show("on");
	hardware.pin2.write(0);
	}
	else if (value == 0)
