我在模仿freebuf上的http://bluereader.org/article/10965311 文章做一个硬件键盘记录。
我的连接是正确的;
arduino IDE版本是1.6.1;
键盘是一个PS2接口;
板子型号是UNO;
PS2Keyboard下载最新的2.4版本http://www.pjrc.com/teensy/td_libs_PS2Keyboard.html
用IDE打开库文件里的example/Simple_Test.pde,编译下载到板子上,发现keyboard.available()总是返回false。
[pre lang="arduino" line="1" file="simple_test,pde"]/* PS2Keyboard library example
PS2Keyboard now requries both pins specified for begin()
keyboard.begin(data_pin, irq_pin);
Valid irq pins:
Arduino Uno: 2, 3
Arduino Due: All pins, except 13 (LED)
Arduino Mega: 2, 3, 18, 19, 20, 21
Teensy 2.0: All pins, except 13 (LED)
Teensy 2.0: 5, 6, 7, 8
Teensy 1.0: 0, 1, 2, 3, 4, 6, 7, 16
Teensy++ 2.0: 0, 1, 2, 3, 18, 19, 36, 37
Teensy++ 1.0: 0, 1, 2, 3, 18, 19, 36, 37
Sanguino: 2, 10, 11
for more information you can read the original wiki in arduino.cc
at http://www.arduino.cc/playground/Main/PS2Keyboard
or http://www.pjrc.com/teensy/td_libs_PS2Keyboard.html
Like the Original library and example this is under LGPL license.
