The connections are simple. Start by plugging in SIO_C to A5 and SIO_D to A4 since this is i2c/twi you must have a 4k7 resistor 10k also works. Make sure you have the resistor to pull up 3.3v not 5v. Also edit twi.c in the arduino ide folder/libraries/Wire/utility search for these lines and comment them out or remove them Code: [Select] // activate internal pullups for twi. digitalWrite(SDA, 1); digitalWrite(SCL, 1); This is to remove the internel pullup resistor by not removing these 2 lines you could cause damage to the sensor. Then plug d7 to digital pin 7 d6 to 6 d5 to 5 d4 to 4 d3 to A3 d2 to A2 d1 to A1 and d0 to A0 now plug in VSYNC to digital pin 3 and PCLK to pin 2. Now change the fuse bits to be exacly the same except enable the CLKOUT pin. This will output a clock run this through a buffer or level shifter to 3.3v if you do not get the 5v signal down to 3.3v it could damage the sensor. The sd card and spi ram is just standard spi wiring nothing special.
