1 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.

2 Electronic Workshop Team Assembly and Testing of Abloy Door Automatics 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.

6 Electronic Workshop Team Design of PCB card on CAD 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

8 Electronic Workshop Team MOUNTING 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. Deltabit fingerprint recognition electronics

9 Electronic Workshop Team Structure 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 2007 Embedded programming Name: (Write your name here) **************************************************************************/ #include "Mega48.h" #include "Deltabit.h" #define TIME_3S 6 // 3 seconds time constant // Return values of Fingerprint library functions #define T_OK 0 // - no error #define T_ERROR 1 // - error detected unsigned char RelayCounter; // Relay on timer as 0,5 s pulses unsigned char LedCounter; // Led timer as 0,5 s pulses void ReadKey()

10 Electronic Workshop Team Final 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) 
