Overview

The bubble level demo demonstrates basic usage of the on-board accelerometer to implement a bubble level. A bubble level utilizes two axes to visually show deviation from a level plane (0 degrees) on a given axis.

Hardware requirements

• Type-C USB cable

• FRDM-MCXN236 board

• Personal Computer

Board settings

No special settings are required.

Prepare the Demo

1. Connect a type-c USB cable between the host PC and the MCU-Link USB port (J10) on the target board.

2. Open a serial terminal with the following settings:

   • 115200 baud rate

   • 8 data bits

   • No parity

   • One stop bit

   • No flow control

3. Download the program to the target board.

4. Either press the reset button on your board or launch the debugger in your IDE to begin running the demo.

Running the demo

When the example runs successfully, you can see the similar information from the terminal as shown below.

Welcome to the BUBBLE example

You will see angle data change in the console when change the angles of board

x= 6 y = 22 x= 8 y = 26 x= 10 y = 28 x= 10 y = 28 x= 11 y = 29 x= 11 y = 29
