python库 pywinio虚拟键盘使用

pywinio github 地址

NOTICE: You must have a ps/2 keyboard connected to your PC if you test on win10 or later, otherwise this sample won't works!

提供win10系统需要ps/2接口的键盘。所以我们掏出老古董ps/2键盘设备。

ps/2接口：

新建keyboardEmulation.py

import pywinio
import time
import atexit

# KeyBoard Commands
# Command port
KBC_KEY_CMD = 0x64
# Data port
KBC_KEY_DATA = 0x60

g_winio = None

def get_winio():
    global g_winio

    if g_winio is None:
            g_winio = pywinio.WinIO()
            def __clear_winio():
                    global g_winio
                    g_winio = None
            atexit.register(__clear_winio)

    return g_winio

def wait_for_buffer_empty():
    '''
    Wait keyboard buffer empty
    '''

    winio = get_winio()

    dwRegVal = 0x02
    while (dwRegVal & 0x02):
            dwRegVal = winio.get_port_byte(KBC_KEY_CMD)

def key_down(scancode):
    winio = get_winio()

    wait_for_buffer_empty();
    winio.set_port_byte(KBC_KEY_CMD, 0xd2);
    wait_for_buffer_empty();
    winio.set_port_byte(KBC_KEY_DATA, scancode)

def key_up(scancode):
    winio = get_winio()

    wait_for_buffer_empty();
    winio.set_port_byte( KBC_KEY_CMD, 0xd2);
    wait_for_buffer_empty();
    winio.set_port_byte( KBC_KEY_DATA, scancode | 0x80);

def key_press(scancode, press_time = 0.2):
    key_down( scancode )
    time.sleep( press_time )
    key_up( scancode )

每个键对应的scancode
