Created October 10, 2016 14:17
A few ways to iterate over pairs of coordinates for drawing a polyline in mindsensorsUI.py
for i in range(len(endpoints)/2):
actendpts.append(self.screenXFromImageCoords(endpoints[i*2],endpoints[i*2+1])) # actual x-coordinate
actendpts.append(self.screenYFromImageCoords(endpoints[i*2],endpoints[i*2+1])) # actual y-coordinate
for i in [x * 2 for x in range(len(endpoints)/2)]: # iterate over every other integer [0, 2, 4, ...]
actendpts.append(self.screenXFromImageCoords(endpoints[i],endpoints[i+1])) # actual x-coordinate
actendpts.append(self.screenYFromImageCoords(endpoints[i],endpoints[i+1])) # actual y-coordinate
for (x,y) in [(endpoints[i*2],endpoints[i*2+1]) for i in range(len(endpoints)/2)]: # iterate over each pair of integers
actendpts.append(self.screenXFromImageCoords(x,y)) # actual x-coordinate

Experimenting using a variable number of arguments in Python for drawing a polyline
def drawPolyLine(*args, **kwargs):
width = kwargs.pop('width', 0)
fill = kwargs.pop('fill', (255,255,255))
display = kwargs.pop('display', True)
print "width: %s\nfill: %s\ndisplay: %s" % (width, fill, display)
for arg in args:
print arg

Various approaches to waiting for the user to be ready before starting an EVShield test or example
evshield.waitForButtonPress(BTN_GO);
evshield.waitForButtonPress(BTN_GO, 1); // "breathing" led pattern: http://www.mindsensors.com/reference/EVShield/html/class_e_v_shield.html#af6551565c91c30c4dcbf3816f45832ed
while (!evshield.getButtonState(BTN_GO)) {
if (millis() % 1000 < 3) {
Serial.println("Press GO button to continue");
}
}

The most simple AWS Lambda function for handling an Alexa request with the new Alexa Node.js SDK
'use strict';
var Alexa = require('alexa-sdk');
var APP_ID = 'amzn1.ask.skill.5f3759df-5f37-59df-5f3759df5f37';
exports.handler = function(event, context, callback) {
var alexa = Alexa.handler(event, context);
alexa.APP_ID = APP_ID;
alexa.registerHandlers(handlers);
alexa.execute();
};

It really should be this simple, but the lambda function returns before the request callback is executed
'use strict';
var Alexa = require('alexa-sdk');
var APP_ID = 'amzn1.ask.skill.5f3759df-5f37-59df-5f3759df5f37';
var request = require('request');
exports.handler = function(event, context, callback) {
var alexa = Alexa.handler(event, context);
alexa.APP_ID = APP_ID;
alexa.registerHandlers(handlers);
