Function Documentation

◆ fxls8974_int_data_ready_callback()

void fxls8974_int_data_ready_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.

Returns: void There is no return value.

Constraints:: None
Yes

Set flag to indicate Sensor has signalled data ready.

Here is the caller graph for this function:

◆ main()

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.

Returns: void There is no return value.

Constraints:: None
No

Initialize the MCU hardware.

Initialize FXLS8974 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 FXLS8974 sensor driver.

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

Configure the FXLS8974 sensor.

Clear the data ready flag, it will be set again by the ISR.

Read new raw sensor data from the FXLS8974.

Process the sample and convert the raw sensor data.
