  12. Level 1 Software Decomposition Grant Fritz

  13. CDH SFT Functional Decomposition Grant Fritz

  14. Display System Overview • Use DVI for easy interface to screens of various sizes • DVI prioritized over VGA to allow for future expandability • Custom display hardware will allow for a simple embedded solution • Removes the need to interface and power a full rendering graphics card • Current image stored to on-board SRAM for fast access • Will be implemented using TFP410 DVI Trasmitter, Altera MaxII CPLD and 6MB SRAM Blake Orth

  15. Display Functional Decomposition Blake Orth

  16. CPLD • Programmed using Verilog through JTAG • Clocked at 165MHz • Takes care of all Video memory Operations • Reads pixel data from SRAM chips and presents it at 24-bit DVI chip input • Write new image data to SRAM chips • Receives new image data from the microcontroller via SPI • Manage all SRAM and DVI control lines Blake Orth

  17. EPM570T144C5N • Max II – 570 Series 144-TQFP • Selected for fast pin-to-pin propagation delay ( down to 4.5ns) • 440 macro-cells allows for reasonably complex logic • Good performance for current draw – at most draws 250mA • Development board being used to develop Verilog code Blake Orth

  18. Display System Hardware • Use TI TFP410 PanelBus DVI Transmitter Blake Orth

  19. TI TFP410 DVI Transmitter • Basic configuration through I2C • Allows settings for resolution, DE generator, and data de-skew • Takes 24-bit True Color pixel data and control signals • Encodes and serializes pixel data to PanelBus DVI and outputs to a standard Single Link DVI Connector Blake Orth

  20. SRAM • Stores current image data (1 image) • 24-bit True Color for each pixel • 8-bits for each color part (RGB) • Three SRAM units will be used • RGB pixel data stored in parallel • One unit for each color • Shared 20-bit address bus • All parts of a single pixel will have a shared address • Shared 8-bit data bus • Bus control handled with output/write enable pins Blake Orth

  21. SRAM Selection • ISSI IS61WV102416 • 1M x 16b SRAM • 8 ns access time • Using 3 modules totals to 6MB of storage Blake Orth

  22. SRAM Modes • SRAM has ability for 16-bit data bus • We are using in 8-bit data bus mode • 20-bit address selects a 16-bit word • Uses /LB and /UB pins to select upper or lower byte Blake Orth

  23. Read Cycle Timing Diagram Notes: - Upper/Lower byte selection control pins not shown here - /CE will be tied active Blake Orth

  25. COM Functional Decomposition Andrew Gunn

  26. GPS • Primary Objective • GPS location used to provide optimal advertisement • RS232 Interface • GPS Handler script • Input a character string • Outputs global variables taken from the char string Andrew Gunn

  27. GPS Handler $GPGGA,184149.00,4000.43877,N,10515.72492,W,1,05,1.68,01633,M,-020,M,,*5C • Type = GPGGA • Time = 18hr 41min 49secs Zulu Time • 4000.43877 North Latitude • 10515.72492 West Longitude • GPS Quality 0=No GPS, 1=GPS, 2=DGPS • Number of Satellites 5 • Altitude in Meters 01633 Andrew Gunn

  28. GPS • Status Update • Full Circle & Fully Functional • GPS Module Receives Data From Satellites • Microprocessor Receives Data String • GPS Handler Parses & Saves Information • Where From Here • Implement Position Logic • If in this Location -> Display This Ad Andrew Gunn

  29. Wifi • Used to update the Display Module with new advertisements & information • Initial Wifly utilizes telnet exclusively • Telnet is completely unsecure • Telnet is Great for sending small strings across local network but not so great at sending large files over internet. • Breakdown, Encrypt, Pack, Transmit, Decrypt, Unpack • In addition to writing the serial and wifi drivers Andrew Gunn

  30. Wiport Wifi Module • Interface RS 232 to UART or Ethernet • Wiport - Breakdown, Encrypt, Pack, Transmit, Decrypt, Unpack • Serial and Wifi Drivers • Wifi Software • Input a character string to change networks • Outputs information or files through Ethernet Andrew Gunn

  31. Bluetooth • Tertiary objective • RS232 thus we can reuse serial driver from GPS • Milestone 2 objective • Overall COM Board • Connects module headers to board stacks • Board Designed in Altium in progress Andrew Gunn

  32. Power Functional Decomposition Wade Pentz

  33. Power System • Each board has its own power stage • Allows each board to be tested separately • Uses linear regulator to provide needed voltage rails • All IC’s use 3.3V • If time allows, a power board will be created • Route IC power • Provide DVI display power using boost converter Wade Pentz

  34. Power Stage • Power switch for each board • Bridge rectifier IC (DF10S) • 1.5 Amp average current rating • 1.1 Volt forward drop • LM317 adjustable linear regulator • 1.5 Amp average current rating • Uses voltage divider to set output voltage • Extremely accurate regulation • Additional protection diodes Wade Pentz
