In order for the FALCON system to be able to communicate with the OV7620 camera module, two resistors must be installed on the underside of the Spartan III development board. This is necessary because the camera configuration interface is I2C-based.
You will need two 2.2K resistors.
First, locate the camera connector A2 on the Spartan III developent board. The resistors will connect between +5V and pins 15 and 17.
This is the only required hardware modification for the FALCON system to operate properly. If desired, PWM cables for serial communications and power can also be added at this time.
