Problems with Digital Pot

sorry about the code here it is


[code lang="cpp"]
#include

void setup()
{
Wire.beginOnPins(5,6);
Wire.begin(); // join i2c bus (address optional for master)
//int reset_command = 4096;
//Wire.write(reset_command);
//int enable = 7168;
//Wire.write(enable);

}

byte val = 0;

void loop()
{
Wire.beginTransmission(46); // transmit to device #44 (0x2c)
// device address is specified in datasheet
//int output = val+1024;
Wire.write(byte(0x00)); // sends instruction byte
Wire.write(val); // sends instruction byte
//Wire.write(output); // sends potentiometer value byte
Wire.endTransmission(); // stop transmitting

val++; // increment value
if(val == 1023) // if reached 64th position (max)
{
val = 0; // start over from lowest value
}
delay(1000);
}[/code]

Digital Potentiometer Help

I am trying to program this digital potentiometer and am beyond stuck. Here is the data sheet

http://www.analog.com/en/digital-to-analog-co...l-potentiometers/ad5272/products/product.html

this is the code I have so far. I am working with the RFduino which uses a different wire library that was downloaded from this site.

http://www.rfduino.com/

The main difference will be the command Wire.beginOnPins(5,6); which sets the SDA and SCL pins to 5 and 6.



At this point all I want it to do is vary the resistance for me. I am measuring the resistance between pins A and W. PLEASE HELP!
