 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

Atmel AT32AP bit AVR ISI LCD Controller OV7690 Sensor Board Sharp VGA LCD Module I2CI2C SD Reader/ Card

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: I 2 C LCD Interface ISI Interface: 12-bit data interface for CMOS cameras

Houses OV7690 Sensor and accompanying capacitors/resistors. OV7690 Sensor (CMOS VGA) – Microcontroller controls imager via SCCB (I 2 C), 8 parallel data lines. Camera takes 30fps and sends it to the Image Sensor Interface (ISI) on the microcontroller.

 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

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
