Function Documentation

fxls896x_int_callback()

void fxls896x_int_callback

(

void *

pUserData

)

This is the Sensor Data Ready ISR implementation.

---

This function sets the flag which indicates if a new sample(s) is available for reading.

Parameters

[in]

pUserData

This is a void pointer to the instance of the user specific data structure for the ISR. void There is no return value.

Set flag to indicate Sensor has signalled data ready.

int main

(

void

)

This is the The main function implementation.

---

This function invokes board initializes routines, then then brings up the sensor and finally enters an endless loop to continuously read available samples.

Parameters

[in]

void

This is no input parameter. void There is no return value.

Initialize the MCU hardware.

Initialize FXLS8964 pin used by FRDM board

Initialize RGB LED pin used by FRDM board

Initialize the I2C driver.

Set the I2C Power mode.

Set the I2C bus speed.

Initialize FXLS896x sensor driver.

Set the task to be executed while waiting for I2C transactions to complete.

Configure the FXLS896x sensor.

Read new raw sensor data from the FXLS8964.

Wake Mode Detected.
