Electronic Workshop Team

The demo consists of Abloy door automatics and Deltabit fingerprint recognition electronics. The competition task

will be performed as pair work.

The task begins with the assembly of the Abloy door and repairing of the fault in its electronic unit. The following

parts of the task are the CAD-design, assembly and, finally, programming of a driving unit for Deltabit finger

print recognition electronics.

The competitors will be told about the assembly task, but there can also be other problems in the apparatus. The competing pair will

get the material and documents of the apparatus. They will have 15 minutes to acquaint themselves with the data. After that they can

ask about the problems.

The competing pair will get a circuit diagram and a simulated model of the object to be designed. They will have 10 minutes time to acquaint themselves with the material. After

that they can discuss with the experts and, possibly, get additional information. Competitors use Eagle CAD (freeware version) which can be found from this link

Electronic Workshop TeamMOUNTING AND TESTING OF A CIRCUIT BOARD

Mount the circuit board that you made! The quality of your work as well as your working methods will all be assessed, so be careful when soldering, extra tin splashes, corrected tin

bridges and the rest of it all will be examined. You can only complete a mounting procedure of components in one way: by doing it well! Pay attention even to the smallest

details.

Electronic Workshop TeamStructure and editing of the program

In writing a program a competitor has to follow a editing pattern that corresponds to the original program. If he/she changes or adds a code it has to be well commented on. The

constants of the program have to be named and defined according to European standards of definition that describes them. In the program code he/she has to use

conditional and repetitive structures in an appropriate way./**************************************************************************Euroskills 2007Embedded programmingName: (Write your name here)**************************************************************************/#include "Mega48.h"#include "Deltabit.h"#define TIME_3S 6 // 3 seconds time constant

Electronic Workshop TeamFinal Programming

The competing pair will have to program the equipment so that the finger data given by the finger print detector will open the door. The pair will demonstrate the operation to the judge.

Implementation of the program

Fingerprint registration 0  … 9  Before an identification of a fingerprint can take place, the finger must be registered.There are ten possible memory locations available. A registration is started by using

number switch 0-9. The number sets the memory location at the same time.Make sure that the fingerprint reader is in a stand-by position (only the red led is on)
