ADXL345 accelerometer integration with TelosB mote

Here is a very simple NesC code for getting X, Y and Z axis value from ADXL345 digital accelerometer with Telosb mote.

Connection
 
ADXL345 GND -> TELOSB 9 pin
ADXL345 VCC  -> TELOSB 1 pin
ADXL345 CS     -> TELOSB 1 pin
ADXL345 SDA  -> TELOSB 8 pin 
ADXL345 SCL  -> TELOSB 6 pin  

Apart from this connect pull-up resistor(10 KOhm) from SDA &SCL to VCC.

Program

Program has  three main files Accelerometer345AppC.nc, Accelerometer345C.nc and Makefile.

Acclerometer345AppC.nc

configuration Accelerometer345AppC {
}

implementation {
  components MainC, Accelerometer345C as App;
  App.Boot -> MainC;
  
  components LedsC;
  App.Leds -> LedsC;

  components new TimerMilliC() as TimerAccel;
  App.TimerAccel -> TimerAccel;

  components new ADXL345C();
  App.Xaxis -> ADXL345C.X;
  App.Yaxis -> ADXL345C.Y;
  App.Zaxis -> ADXL345C.Z;
  App.AccelControl -> ADXL345C.SplitControl;
}
