I purchased the breakout for ADNS2620 Optical Mouse Sensor. I removed the kapton tape on the sensor.
I am using an Adruino Duemilanove (ATMEGA328). I hooked up the 4 wires as follows: GND to GND, VCC to 5V, SDIO to Analog 4, SCL to Analog 5.
I downloaded ADNS2620 Arduino Library from (Breakout for ADNS2620 Optical Mouse Sensor - BOB-10105 - SparkFun Electronics), compiled and ran the example, but I keep getting:
x:FF y:FF

Here is the code used:
/* ADNS2620 Example Sketch
- Demonstrates how to use the ADNS2620 Library to interface with the mouse sensor
- on the ADNS2620 evaluation board from SparkFun Electronics
- More register definitions are located in the 'adns2620.h' file. Read the
- ADNS2620 datasheet to understand how to use the registers.
- After loading the sketch to the ADNS2620 evaluation board, open the serial terminal
- using a baud rate of 9600 to see the output from the ADNS2620 sensor.
