Overview

The KPP Example project is a demonstration program that uses the KSDK software to manipulate the Keypad MATRIX. The example is use the continuous column and rows as 44 or 88 matrix to show the example.

SDK version

  • Version: 2.15.000

Toolchain supported

  • IAR embedded Workbench 9.40.1
  • Keil MDK 5.38.1
  • GCC ARM Embedded 12.2
  • MCUXpresso 11.8.0

Hardware requirements

  • Mini/micro USB cable
  • EVKB-IMXRT1050 board
  • Personal Computer

Board settings

Matrix and Jumper settings for KPP:

row1 <-----> J22 #2 row2 <-----> J23 #3 row3 <-----> J22 #7 row4 <-----> J23 #6 col1 <-----> J22 #1 col2 <-----> J23 #4 col3 <-----> J22 #8 col4 <-----> J23 #5

Prepare the Demo

  1. Connect a USB cable between the host PC and the OpenSDA USB port 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. Connect the 4*4 matrix to the Jumpers mentioned above.
  4. Download the program to the target board.
  5. Either press the reset button on your board or launch the debugger in your IDE to begin running the demo.

Running the demo

When you press any key on matrix, the log will show the right key you have pressed. If the press is long, it will add the long press mention. The log would be seen on the OpenSDA terminal like:

 KPP Driver Example Start.
  
 Key SW1 was pressed.

 Key SW3 was pressed.

 This was a long press.
