blindman2k / MAX3421E.device.nut

Created July 2, 2014 20:31

First attempt at a driver for the MAX3421E USB Host


	// -----------------------------------------------------------------------------
	// USB Host Shield pinouts
	//
	// 1- CS (not sure if it's active high/low)
	// 2- MISO
	// 5- SCLK
	// 7- MOSI
	// 8- RESET (also not sure about active high/low)
	// 9- Interrupt (not sure if this is useful for anything)

blindman2k / LEDDisplay.agent.nut

Last active August 29, 2015 14:03

This is some old code we used to light up the 16x16 LED display. The image loading no longer works because we lost the PHP code which used ImageMagick to convert the JPEGs and animated GIFS into bitstreams. But the rest works fine.

	// ------------------------------------------------------------------------
	// Takes a string, renders it and sends it to the device for display
	text <- null;
	function displayText(_text) {
	device.send("text", _text);
	text = _text;
	}

Last active August 29, 2015 14:04

This HTTPRetry class automatically retries http requests when the agent backend throttles the request with a 429 error. Use it as you would the http object.

	HTTPRetry.get("http://icanhazip.com").sendasync(function(res) {
	if (res.statuscode == 200) {
	server.log(res.body);
	} else {
	server.log("Error: " + res.statuscode);
	}
	});

blindman2k / httpplus.agent.nut

Created July 23, 2014 00:07

HTTPPlus is an optimised http object replacement. It adds retry and redirect support for Imp agents. It also automatically converts tables to JSON requests.

	// -----------------------------------------------------------------------------
	class HTTPPlus {

	_http = null;

	// .........................................................................
	// Keep a copy of the original http object for internal use
	constructor() {
	_http = http;
	}

blindman2k / number_format.nut

Created August 22, 2014 18:13

A handy utility function for formatting a number (integer or float) with a specified number of decimal places and commas at the thousand places.

	function number_format(num, decimals=null, separator=",") {
	// Fix the decimals
	if (decimals == null) {
	if (typeof num == "string") decimals = 0;
	else if (typeof num == "integer") decimals = 0;
	else if (typeof num == "float") decimals = 2;
	else return num;
	}
	// Check we have a number or convert to one if required
	if (typeof num == "string") {

blindman2k / tempbug.agent.nut
