linux - read raw input from keyboard in python -


i'm trying raw input of keyboard in python. have logitech gaming keyboard programmable keys, logitech doesn't provide drivers linux. thought (try) write own driver this. in think solution like:

with open('/dev/keyboard', 'rb') keyboard:     while true:         inp = keyboard.read()         -do something-

english isn't native language. if find errors, please correct it.


two input methods rely on os handling keyboard

import sys line in sys.stdin.readlines():     print line

this 1 "simple" solution problem considering reads sys.stdin you'll need driver , if os strips stuff along way break anyways.

this solution (linux afaik):

import sys, select, tty, termios class nonblockingconsole(object):     def __enter__(self):         self.old_settings = termios.tcgetattr(sys.stdin)         tty.setcbreak(sys.stdin.fileno())         return self      def __exit__(self, type, value, traceback):         termios.tcsetattr(sys.stdin, termios.tcsadrain, self.old_settings)      def get_data(self):         try:             if select.select([sys.stdin], [], [], 0) == ([sys.stdin], [], []):                 return sys.stdin.read(1)         except:             return '[ctrl-c]'         return false  data = '' printed = '' last = '' nonblockingconsole() nbc:     while 1:         c = nbc.get_data()         if c:             if c == '\x1b': # x1b esc                 break             elif c == '\x7f': # backspace                 data = data[:-1]                 printed = data[:-1]                 last = ''                 sys.stdout.write('\b')             elif c == '[ctrl-c]':                 data = ''                 last = ''                 sys.stdout.write('\n')             elif c == '\n': # it's return                 sys.stdout.write('\n')                 # parse data here                 data = ''             else:                 data += (c)                 last = c                 sys.stdout.write(c)

driver issue?

if none of above work, woun't able keys within python.
you'll need actual driver can parse data sent keyboard not normal keyboard event on usb stack, meaning.. way low-level python , you're out of luck... unless know how build linux drivers.

anyway, have at: http://ubuntuforums.org/showthread.php?t=1490385

looks more people have tried it.

trying pyusb

http://pyusb.sourceforge.net/docs/1.0/tutorial.html

you try pyusb solution , fetch raw data usb socket, again.. if g-keys not registered "traditional" usb data might dropped , won't recieve it.

hooking on input pipes in linux

another untested method, might work //hackaday: enter image description here

keyboard - C++ GetAsyncKeyState alternative -

i using windows.h library's getasynckeystate function define key pushed on keyboard . here program returns int value of pushed key example. #include <iostream> #include <windows.h> using namespace std; int main (){ char i; for(i=8;i<190;i++){ if(getasynckeystate(i)== -32767){ cout<<int (i)<<endl; } } return 0; } but trying make opengl simple game , function appeared slow . there function not need cycle 180 times , if statement . thanks you're trying make opengl game, you're going use glfw. if that's case can away using glfwgetkey() such: if (glfwgetkey(glfw_key_up) == glfw_press) {...} if (glfwgetkey(glfw_key_down) == glfw_press) {...} that method nicely explained in tutorial 6 opengl-tutorial.org . should start first tutorial of beginners tutorials , later intermediate tutorials . if you're going make win32 window can listen wm_keydown or wm_keyup messages , virtua
