MakeCode Extension for Emakefun Speech Recognizer

Introduction

• This project implements a MakeCode extension for Microbit to integrate the Emakefun matrix keyboard module's capabilities on the micro:bit.

• Through this extension, you can easily interface with the Emakefun matrix keyboard to detect key presses and read input in the MakeCode Blocks editor.

• You can get this module here.

Hardware

TODO

Usage

• Use the createMatrixKeyboard block to create an instance of the matrix keyboard and configure the I2C address.

• In a loop, use the Update block first and use the isClicked block to check if a key is clicked and get the return value.

• Optionally, based on the return value of isClicked, you can perform appropriate actions. For example:

  • If a number key is clicked, display the corresponding number.

  • If a letter key is clicked, display the corresponding letter.

  • If a special character key is clicked, display the character.

Example

You can copy the code from below or view the project (blocks and JavaScript view) here.

let matrix_keyboard = Emakefun.createMatrixKeyboard(0x65);
basic.forever(function() {
  matrix_keyboard.update();

  if (matrix_keyboard.isClicked(Emakefun.MatrixKeyboardKey.KEY_0)) {
    basic.showNumber(0);
  } else if (matrix_keyboard.isClicked(Emakefun.MatrixKeyboardKey.KEY_1)) {
    basic.showNumber(1);
  } else if (matrix_keyboard.isClicked(Emakefun.MatrixKeyboardKey.KEY_2)) {
    basic.showNumber(2);
  } else if (matrix_keyboard.isClicked(Emakefun.MatrixKeyboardKey.KEY_3)) {
    basic.showNumber(3);
  } else if (matrix_keyboard.isClicked(Emakefun.MatrixKeyboardKey.KEY_4)) {
    basic.showNumber(4);
  } else if (matrix_keyboard.isClicked(Emakefun.MatrixKeyboardKey.KEY_5)) {
    basic.showNumber(5);
  } else if (matrix_keyboard.isClicked(Emakefun.MatrixKeyboardKey.KEY_6)) {
    basic.showNumber(6);
  } else if (matrix_keyboard.isClicked(Emakefun.MatrixKeyboardKey.KEY_7)) {
    basic.showNumber(7);
  } else if (matrix_keyboard.isClicked(Emakefun.MatrixKeyboardKey.KEY_8)) {
    basic.showNumber(8);
  } else if (matrix_keyboard.isClicked(Emakefun.MatrixKeyboardKey.KEY_9)) {
    basic.showNumber(9);
  } else if (matrix_keyboard.isClicked(Emakefun.MatrixKeyboardKey.KEY_A)) {
    basic.showString('A');
  } else if (matrix_keyboard.isClicked(Emakefun.MatrixKeyboardKey.KEY_B)) {
    basic.showString('B');
  } else if (matrix_keyboard.isClicked(Emakefun.MatrixKeyboardKey.KEY_C)) {
    basic.showString('C');
  } else if (matrix_keyboard.isClicked(Emakefun.MatrixKeyboardKey.KEY_D)) {
    basic.showString('D');
  } else if (matrix_keyboard.isClicked(Emakefun.MatrixKeyboardKey.KEY_ASTERISK)) {
    basic.showString('*');
  } else if (matrix_keyboard.isClicked(Emakefun.MatrixKeyboardKey.KEY_NUMBER_SIGN)) {
    basic.showString('#');
  }
})
