LDC1612: LDC1612

HI All ,

i have trying to interface LDC1612 chip to arduino microcontroller .
i have write the code as below I2C read and write operation done properly.
But my receiving  is continuously 0 . can anyone resolve my problem. 

#include <Wire.h>

int LDC = 0x2A;

int CH0MSB = 0x00;

int CH0LSB = 0x01;

int CH1MSB = 0x02;

int CH1LSB = 0x03;

long initial0 = 0;

long initial1 = 0;

 
unsigned long readChannel0()

{

  unsigned long val = 0;

  word c = 0; //a word stores a 16-bit unsigned number

  word d = 0;

  c = readValue(LDC, CH0MSB);

  d = readValue(LDC, CH0LSB);

  val = c;

  val <<= 16;

  val += d;

  return val;

}

 
unsigned long readChannel1()

{

  unsigned long val = 0;

  word c = 0; //a word stores a 16-bit unsigned number

  word d = 0;

  c = readValue(LDC, CH1MSB);

  d = readValue(LDC, CH1LSB);

  val = c;

  val <<= 16;

  val += d;

  return val;

}

 

void Calibrate()

{

  initial0 = readChannel0();

  initial1 = readChannel1();

}

 

word readValue (int LDC, int reg)

{

  int a = 0;

  int b = 0;

  word value = 0;

  Wire.beginTransmission(LDC);

  Wire.write(reg);

  Wire.endTransmission();

  Wire.requestFrom(LDC, 2);

  while (Wire.available())

  {

    a = Wire.read();

    b = Wire.read();

  }

  value = a;

  value <<= 8;

  value += b;
  
  return value;

}

 

 

void writeConfig(int LDC, int reg, int MSB, int LSB)

{

  Wire.beginTransmission(LDC);

  Wire.write(reg);

  Wire.write(MSB);

  Wire.write(LSB);

  Wire.endTransmission();

}

 

void Configuration()

{

  writeConfig(LDC, 0x14, 0x10, 0x02);//CLOCK_DIVIDERS_CH0

  writeConfig(LDC, 0x1E, 0x90, 0x00);//DRIVE_CURRENT_CH0

  writeConfig(LDC, 0x10, 0x00, 0x0A);//SETTLECOUNT_CH0

  writeConfig(LDC, 0x08, 0x04, 0xD6);//RCOUNT_CH0
  
  writeConfig(LDC, 0x15, 0x10, 0x02);//CLOCK_DIVIDERS_CH1

  writeConfig(LDC, 0x1F, 0x90, 0x00);//DRIVE_CURRENT_CH1

  writeConfig(LDC, 0x11, 0x00, 0x0A);//SETTLECOUNT_CH1

  writeConfig(LDC, 0x09, 0x04, 0xD6);//RCOUNT_CH1
    
  writeConfig(LDC, 0x19, 0x00, 0x00);//ERROR_CONFIG
  
  writeConfig(LDC, 0x1B, 0x82, 0x0C);//MUX_CONFIG

}

 

void setup()

{

  Wire.begin();

  Serial.begin(9600);

 // writeConfig(LDC, 0x1C, 0x10, 0x00);//reset device
   
  delay(200);
  
  //writeConfig(LDC, 0x1C, 0x00, 0x00);//reset device
  
  Configuration();

  delay(500);

  Calibrate();

}

 

void loop()

{

  unsigned long data0 = readChannel0();

//  unsigned long data1 = readChannel1();

  Serial.println(data0);

//  Serial.println(data1);
 
 /* word deviceid = readValue(0x2A,0x7E);
  
  Serial.println(deviceid,HEX);
  
  word device = readValue(0x2A,0x7F);
  
  Serial.println(device,HEX);*/
  delay(5000);
