◆ main()

int main ( void )

Main function.

Initialize the I2C driver.

Set the I2C Power mode.

Set the I2C bus speed.

Initialize the MMA845x sensor driver.

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

Configure the MMA845x sensor driver with FIFO mode.

Wait for data ready from the MMA845x.

Read the raw sensor data from the MMA845x.

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