rabird.winio

A wrapper library for winio .

Thanks for the great WinIO library which comes from Yariv Kaplan.

The WinIO library binary distribution will download from http://www.internals.com/ during setup.

Usage

Keyboard Emulation

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!

import rabird.winio
import time
import atexit

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

__winio = None

def __get_winio():
    global __winio

    if __winio is None:
            __winio = rabird.winio.WinIO()
            def __clear_winio():
                    global __winio
                    __winio = None
            atexit.register(__clear_winio)

    return __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 )


# Press 'A' key
# Scancodes references : https://www.win.tue.nl/~aeb/linux/kbd/scancodes-1.html
key_press(0x1E)

Privilege Requirements

WinIo requires administrative privileges to run properly. This can be achieved by:

Using WinIo from a service running as LocalSystem (SE_LOAD_DRIVER_NAME privilege must be explicitly enabled).
Embedding a manifest file in the application that requests privilege elevation.
Requiring the user to choose the "Run as Administrator" option when launching the application.

The included C# samples demonstrate using an embedded manifest file to request privilege elevation.

Driver Signing Requirements on 64-bit Systems

64-bit versions of Windows only load device drivers that are signed by a code signing certificate issued by a public CA such as Verisign, Thawte, etc. WinIo64.sys must not be deployed on production machines unless a code signing certificate is obtained and used to sign this file. The bundled copy of WinIo64.sys is signed with a self-signed certificate and can only be used on development/test machines with Windows running in a special "test" mode. In order to use the bundled version of WinIo64.sys, you need to take the following steps:

Open an elevated command window by right-clicking the icon and clicking "Run as Administrator".
Type the following command to enable test-signing:

bcdedit.exe /set TESTSIGNING ON

Reboot the machine
