  1. Trocascope XC2000 ver. 2.0 Brought to you by: Smooth Operation Chris Kitt, Brenda Marcum, Jacob Oliver, Michael Roth, and Andrew Yuan

  2. Trocascope XC2000 ver. 2.0 • Eliminate one port by incorporating the camera onto the tool port • More convenient for surgical team - fewer hands required and viewable screen • Less traumatic for patient

  3. Overview I2C Atmel AT32AP7000 32bit AVR OV7690 Sensor Board ISI SD Reader/Card Sharp VGA LCD Module LCD Controller

  4. Atmel AT32AP7000 • 256-BGA 32-bit Microcontroller • External Memory Interface • (SDRAM, DataFlash, SRAM, MMC, SD, Compact Flash, Smart Media, NAND Flash) • SD Card holds Linux boot-up protocol and all Linux applications ran on board • 4 USART • Two-Wire Interface: I2C • LCD Interface • ISI Interface: 12-bit data interface for CMOS cameras

  5. Development Board

  6. Sensor Board • Houses OV7690 Sensor and accompanying capacitors/resistors. • OV7690 Sensor (CMOS VGA) • Microcontroller controls imager via SCCB (I2C), 8 parallel data lines. • Camera takes 640x480 @ 30fps and sends it to the Image Sensor Interface (ISI) on the microcontroller.

  7. LCD • Sharp LS037V7DW01 • Connected via Microcontroller LCD Interface. • Microcontroller takes data from imager, displays it on the LCD in VGA format. • Utilizes RGB parallel input with 18 bits of color

  23. Software Overview • Linux running on stk1000 • Prebuilt drivers for on board LCD • Edit to work with our LCD • ISI Linux drivers • Tweak for our Imager • Install slightly modified Linux and bootloaders on custom board

  24. Software Hierarchy

  25. Immediate Software Goals • Get Development Environment Functional • Ubuntu 8.04 • AVR32 Buildroot 2.2.0 • AVR32 GNU Toolchain 2.1.4 • AVR32 Studio 2.1 • Display an image on the LCD

  26. Updated Schedule

  27. Parts List

  28. Division of Labor

  29. Risk Analysis • Running into issues with getting Linux program running on board • Unfamiliar with Linux • Even with this running, concerns about getting sample code to work • Small traces = additional costs not originally budgeted for • Long turn around time for PCBs adds additional delays • Complexity of Microprocessor layout is taking longer to design than expected
