/********************* CODE INFORMATON ******************************
Date of creation: 30-09-2017
Authors: Danny Eldering & Ricardo Molenaar

(c) Copyright by Momo Medical BV.
Current version name: 2.1.3
Date of modification: 18-10-2017
Purpose of this file: Code for LPC1768 microcontroller for controlling buttons, LED's and communicate to PI
Update ‘what’s new in this version?’: New structure added.
Readability improved.
Code optimized (variables and functions).
Todo: -> Fix LED issue (yellow and red flashes at random moments);
-> Optimize functions / improve readability;
-> Split functions in seperate files?;
-> Fix when sensorplate is not connected;
-> Rule 570: if statement change to turn off LED's when power is plugged out (also related to rule 106).
-> For the speaker two outputs of the uC are used. Add MOSFET with external supply and control these by uC?
