Macro Definition Documentation

◆ FIFO_SIZE

#define FIFO_SIZE 16

The watermark value configured for FXLS8471Q FIFO Buffer.

Referenced by main().

Function Documentation

◆ 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 the SPI driver.

Set the SPI Power mode.

Set the SPI Slave speed.

Initialize the FXLS8471Q sensor driver.

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

Configure the FXLS8471Q sensor driver.

Wait for the FIFO watermark event.

Read the raw sensor data from the FXLS8471Q.

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