pyvjoy is a set of Python bindings for vJoy (vjoystick.sourceforge.net)
With this library you can easily set Axis and Button values on any vJoy device.
Low-level bindings are provided in pyvjoy._sdk as well as a (hopefully) slightly more 'Pythonic' API in the pyvjoy.VJoyDevice() object.
Currently vJoyInterface.dll is looked for inside the pyvjoy directory only so place the desired version of that file there to use. (Note: this library currently only works with the x86 dll!)
"Pointy's Joystick Test App" is very useful when testing vJoy and this library: http://www.planetpointy.co.uk/joystick-test-application/
#Pythonic API, item-at-a-time
j = pyvjoy.VJoyDevice(1)
#turn button number 15 on
#Notice the args are (buttonID,state) whereas vJoy's native API is the other way around.
#turn button 15 off again
#Set X axis to fully left
#Set X axis to fully right
#The 'efficient' method as described in vJoy's docs - set multiple values at once
>>> <pyvjoy._sdk._JOYSTICK_POSITION_V2 at 0x....>
j.data.lButtons = 19 # buttons number 1,2 and 5 (1+2+16)
j.data.wAxisX = 0x2000
#send data to vJoy device
#Lower-level API just wraps the functions in the DLL as thinly as possible, with some attempt to raise exceptions instead of return codes.
