1. slide 1 Project 1 Task 1 T&N3311 PJ1 Information & Communications Technology HD in Telecommunications and Networking Survey Form Simply put a cross in the appropriate answer for each question, e.g. The contact hours were sufficient Leave the other boxes blank  NeutralAgree Strongly

2. slide 2 Project 1 Task 1 T&N3311 PJ1 Information & Communications Technology HD in Telecommunications and Networking Task 1 Briefing The Design of an Electronic Dice

3. slide 3 Project 1 Task 1 T&N3311 PJ1 Information & Communications Technology HD in Telecommunications and Networking The Technology  Based on the Microcontroller card you have built  Controlled by a C program in PC - this is what you must write  You do NOT have to program the microcontroller  ASCII characters are used to transfer data between PC and microcontroller

5. slide 5 Project 1 Task 1 T&N3311 PJ1 Information & Communications Technology HD in Telecommunications and Networking What the Circuit Does  All communications is via RS232 (9600,N,8)  When the button is pressed – circuit sends Y  When the button is released – circuit sends N  Bit pattern of received character controls LEDs example: receives character @ which is 1000000 bit 6 LED turns ON, all others are off. or: receives character A which is ASCII 1000001 bit 0 and 6 LEDs turn ON.

7. slide 7 Project 1 Task 1 T&N3311 PJ1 Information & Communications Technology HD in Telecommunications and Networking Example of Controlling LEDs bit 6bit 5 bit 4bit 3bit 2 bit 1bit 0 Receives the ASCII character 4 This has bit pattern 0110100 So LEDs of bits 2, 4 and 5 are on Character to Control Display

8. slide 8 Project 1 Task 1 T&N3311 PJ1 Information & Communications Technology HD in Telecommunications and Networking Flow of Program Start: Wait until button pressed (receive Y) count=0 While button pressed (not received N) increment count if (count=7) count=1 LED pattern=count delay Return to Start

9. slide 9 Project 1 Task 1 T&N3311 PJ1 Information & Communications Technology HD in Telecommunications and Networking What you have to do  Use hyperterminal or to familiarize yourself with the way the circuit board works  Practice using serial communications with C (see Help about Serial Communications)  Write pseudocode to describe the operation of the PC program  Write and debug your C program

10. slide 10 Project 1 Task 1 T&N3311 PJ1 Information & Communications Technology HD in Telecommunications and Networking What you must submit  You should submit a short report on your program containing: o The Pseudocode o The C program (including comments) o A description of the operation of the program  Report to be submitted in week 20  Your lecturer will want to see the program working in week 20

11. slide 11 Project 1 Task 1 T&N3311 PJ1 Information & Communications Technology HD in Telecommunications and Networking For the Brighter Students  It is possible that some groups will finish the program before week 20.  Think how the program can be extended or  Design another game (or application) for the board.  Credit will be given for extra work done.
