dmccreary / Orbeon XForms JavaScript using xf:load and AVTs

Created October 9, 2013 15:12

With Orbeon, you can pass parameters between an XForms application and a JavaScript function using the <xf:load> statement and Attribute Value Templates (AVTs). This example shows you how it is done. Note that there are a few samples (in comments) that do not work due to limitations in the ways parameters are passed. Thanks to Alessandro Vernet …

dmccreary / Arduino LED fader

Created November 12, 2013 04:28

Sample Arduino C program to fade and LED slowly on and off and control the delay time of ramp up, on, ramp down and off.

	/* Based on the Arduino fader example
	Dan McCreary
	Nov. 2013 */
	int ledPin = 11; // LED connected from digital pin 11 to ground
	int maxb = 155; // max brightness 0 to 255
	int inc = 1; // step increment value: typical values are from 1 to 10
	int slope = 20; // delay at each step in milliseconds - combine with inc to change speed transition
	int delayOn = 1000; // how long to stay at max brightness in milliseconds
	int delayOff = 2000; // how long to stay off in milliseconds

Update to Chad Killingsworth's TinyMCE plugin that strips markup before character count.

	tinymce.create("tinymce.plugins.HTMLCharCount", {
	_MaxLength: 0, _CharsString: "", _RemainString: "", init: function (a, b) {
	var c = this; c._MaxLength = a.getParam("htmlcharcount_maxchars", 0);
	if (a.getParam("theme", "") != "advanced") {
	return
	}
	c._CharsString = " " + a.getLang("htmlcharcount.chars", "Characters");
	c._RemainString = " " + a.getLang("htmlcharcount.remaining", "Characters remaining");

Demonstration of reading digital temperature and relative humidity from DHT22 sensor with Arduino UNO. You can purchase the device here * https://www.sparkfun.com/products/10167 Based on Ben Adams driver at http://www.sparkfun.com/products/10167 Using Arduino 1.5.4 IDE I got the following compile data: Sketch uses 5,406 bytes (16%) of program st…

	// you can get the header file at http://www.sparkfun.com/products/10167
	#include <DHT22.h>
	// Only used for sprintf
	#include <stdio.h>

	// Data wire is plugged into port 2 on the Arduino
	#define DHT22_PIN 2
	// Ben's original code suggested a 4.7K resistor between VCC and the data pin (strong pullup)
	// But I found this was not needed since the pullup can be in software

Hot to detect what version of XQuery you are running using the newer XQuery 3.0 function-lookup() function. Note: this approach will not work on XQuery 1.0.

	xquery version "3.0";
	(: Sample XQuery program to detect what version of XQuery you are running.
	Note this ONLY works in XQuery 3.0. It will fail in any XQuery "1.0" implementation such as Saxon HE.
	Unlike many things in XQuery, this function is not elegant. Perhaps XQuery "4.0" will include a function such system-property('version')
	Note that fn:function-lookup() returns a function if it exists and null if it does not.
	See http://www.w3.org/TR/xpath-functions-30/#func-function-lookup
	Thanks to http://stackoverflow.com/users/1451599/dirkk for the solution
	http://stackoverflow.com/questions/20849295/how-can-i-write-an-xquery-that-can-test-what-version-of-xquery-is-being-used

Last active January 4, 2016 05:09

Position sensor code for RC Helicopter target landing game. Try to land your RC Helicopter (Syma S107 preferred) in a 10cm target. Sensor detect how far you are away from center. Three LEDs (green, orange and red) will tell your score.

	/*
	Arduino 1 Dimensional RC Helicopter Target Center Detection
	Mount sensor near a circle 10 cm across
	Try to land your RC Helicopter (Syma S107 preferred)
	If the Green LED lights up you are in the target zone and you get 3 points
	If the Orange LED lights up you near but not in the target zone and you get 1 points
	If the Red LED lights up you only get a single point
