Function Documentation

◆ fxas21002_isr()

void fxas21002_isr ( 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.

Definition at line 96 of file fxas21002_interrupt.c.

References fxas21002Interrupt.

Referenced by main().

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 INT1_FXAS21002 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 the FXAS21002 sensor driver.

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

Configure the FXAS21002 sensor driver.

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

Read the raw sensor data from the FXAS21002.

Convert the raw sensor data to signed 16-bit container for display to the debug port.
