RTOS/CC2650: CC2650 I2C interface ,I2cTx() ,I2cRx() ,Iam unable to write or read From sensor controller(Ambient Light Sensor)

Hi Vamsi,

I would suggest you look at the "I2C Light Sensor" example in Sensor Controller Studio as well as the code example found in the "I2C Master" chapter of the help section.

For example, you would find that "I2C_OP_WRITE"  is simply saying if it is a read or write operation you expect to be doing, for this to make any sense you also have to "OR"-in the device address.

Copy pasted from the help section:

// Accelerometer (I2C address 0x86+W): Write X register address (0x04)
i2cStart();
i2cTx(0x86 | I2C_OP_WRITE);
i2cTx(0x04);

// If successful ...
if (state.i2cStatus == 0x0000) {

    // Accelerometer (I2C address 0x86+R): Read X/Y/Z register values
    i2cRepeatedStart();
    i2cTx(0x86 | I2C_OP_READ);
    i2cRxAck(output.x);
    i2cRxAck(output.y);
    i2cRxNack(output.z);
}
i2cStop();

// Handle errors, if any ...
if (state.i2cStatus != 0x0000) {
    ... Handle errors ...
}
