Re: How to make a interface ps/2 keyboard or mouse with arm7
You can find many examples on net. One year ago I used PC keyboard with mcu (AT89c52).
Kayboard has 4 active pins: +5V, GND, CLK and DATA
CLK and DATA has his internal pull ups so you can connect them directly ro mcu pins. When download code table you can make software to recognize which key is pressed.
