3. October 07, 2003Created by: M. Campo3 Traditional Poster Making  Time Consuming  Risky  Messy  Inconsistent

4. October 07, 2003Created by: P'n'P Team4 Problem An automated system that gets text from a file and plots, using a pen, onto poster board.

5. October 07, 2003Created by: M. Loiselle5 Solution Crossbreed between a Printer and a stationary XY Plotter

6. October 07, 2003Created by: P'n'P Team6 Solution  A gantry that moves the pen in the x direction like a stationary plotter.  A roller will move the poster board in the y direction like a printer.

7. October 07, 2003Created by: P'n'P Team7 Week #8 Functionality  Make letters using a low resolution dot matrix.  Minimal model (of at least one letter)  Upper case letters  One size poster board

15. October 07, 2003Created by: Hesse15 Power Supply AC Current Outlet AC / DC Converter DC Current Runs on standard wall outlet Produces three separate DC sources: - Stepper Motors, Solenoid, and Micro Board

16. October 07, 2003Created by: Hesse16 Motor Driver Chip Drive motor coils in order Reads step input from HC08 Reads direction input from HC08 Same type of chip to drive roller and pulley motor

17. October 07, 2003Created by: Hesse17 The Micro Controller Reads encoded text from serial port Stores data for each letter model Communicates with Motor Driver Chip

18. October 07, 2003Created by: Hesse & Searle18 Computer Concepts  Combination of C and assembly language  Read user input or existing file  Use PC serial port to transfer data  Read and write letter model  Motor timing control with the HC08  Motor direction control with the HC08

19. October 07, 2003Created by: Hesse & Searle19 Letter Matrix  16 x 16 Matrix  Each block = 1 byte of data  32 bytes / letter model  Executes line by line  ‘Y’ Example:  Data in A2 = 01100000 = 0x60

20. October 07, 2003Created by: Hesse & Searle20 Printing Pseudo Code (HC08)  Looks for first inputted character  Compares character to “tags” in memory  Once the correct “tag” is found, program prints the current line (line# = 1)  Continues for remaining characters in the inputted sentence  Increments line number and repeats until sentence is complete
