Experiment no. 2
  • L2.1 Name:


    • Freescal FRDM KL25 - ByteDisplay extension



  • E2.1 Overview, purpose.


    • The experiment aims to explore the FRDM platform architecture and the use of C ++ classes for bit / byte / bus level input / output. At the end of the lab, you will find useful information on how to build the Arduino digital extension for FRDM for the hands-on learning universe.

  • L2.3 Resources:


    • - The FRDM KL25 Development Platform, USB Cable
    - ByteDisplay Extension
    - PC Computer with Web Browser
    - Accces Internet at www.mbed.org


  • L2.4 Programs example:


    • Prototype Program 1
    Prototype Program 2



  • L2.5 Running / tracking experiment:


      • Analyze the FRDM KL25 platform documentation on mbed.org;
    • Analyze the layout of the ByteDisplay interface shown below:

    • Connect the ByteDisplay interface to FRDM;
    • Connect the FRDM platform to the PC via USB;
    • Compile the prototype program, and track the execution on the FRDM.




  • L2.6 Proposed Issues:


    • 1. Create a program that allows you to determine the maximum frequency of activation of a LED in ByteDisplay;




    2. Make a program that will generate 2 counts on 4 bits;
    3. Make a program that will move right 1 bit visible on ByteDisplay;

    4. Make a program that will move left 1 bit visible on ByteDisplay;
    5. Make a 11-bit counter on the FRDM with Byte display.



  • L2.7 The experiment may be extended to:


    • - Intelligent Vehicle Development in NXP Cup 2018/9 ;
    - Making software troubleshooters;
    - Making digital extensions for computers;
    - Realization of LED lighting systems;
