Function Documentation

◆ fxls8962_int_data_ready_callback()

void fxls8962_int_data_ready_callback ( void * pUserData )

The Data ready ISR callback function.

Set flag to indicate Sensor has signalled data ready.

References gFxls8962DataReady.

Referenced by main().

Here is the caller graph for this function:

◆ main()

int main ( void )

Main function.

Initialize the MCU hardware.

Initialize FXLS8962 pin used by FRDM board

Initialize RGB LED pin used by FRDM board

Initialize the SPI driver.

Set the SPI Power mode.

Set the SPI Slave speed.

Initialize FXLS8962 sensor driver.

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

Configure the FXLS8962 sensor.

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

Read new raw sensor data from the FXLS8962.

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

Display to the debug port the last sample. NOTE: PRINTF is relatively expensive in terms of CPU time, specially when used with-in execution loop.
