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 fxls8974 sensor driver.

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

Configure the FXLS8974 sensor driver.

Wait for data ready from the FXLS8974.

Read the raw sensor data from the FXLS8974.

Convert the raw sensor data for display to the debug port.
