• 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

• 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.

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

Miscellaneous Tasks/Testing All

• 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
