ricardo_95 36:d10f368d037b 7 Current version name: 2.1.3
ricardo_95 36:d10f368d037b 8 Date of modification: 18-10-2017
ricardo_95 36:d10f368d037b 9 Purpose of this file: Code for LPC1768 microcontroller for controlling buttons, LED's and communicate to PI
ricardo_95 36:d10f368d037b 10 Update ‘what’s new in this version?’: New structure added.
ricardo_95 36:d10f368d037b 11 Readability improved.
ricardo_95 36:d10f368d037b 12 Code optimized (variables and functions).
ricardo_95 36:d10f368d037b 13 Todo: -> Fix LED issue (yellow and red flashes at random moments);
ricardo_95 36:d10f368d037b 14 -> Optimize functions / improve readability;
ricardo_95 36:d10f368d037b 15 -> Split functions in seperate files?;
ricardo_95 36:d10f368d037b 16 -> Fix when sensorplate is not connected;
ricardo_95 36:d10f368d037b 17 -> Rule 570: if statement change to turn off LED's when power is plugged out (also related to rule 106).
ricardo_95 36:d10f368d037b 18 -> For the speaker two outputs of the uC are used. Add MOSFET with external supply and control these by uC?
