How are you? I hope you can help me with something, I have a problem from Artix Linux, I want to connect my Wii Remote to use it as a Gamepad, it does not want to work because the uinput module does not want to interpret the events associated with Gamepad Inputs, it does not catch for example "BTN_A" or others, but if I put another as "KEY_A" if it recognizes it but acts as a keyboard input in that case. What solution do you propose?
Note that I use WMinput, and I have already installed cwiid, wminput, and even fixed the uinput module in the kernel.
I had the same problem. In my case the error was that I tried to pass the button as an unsigned char. I realized later that BTN_A is not defined as 131 but as 0x131, so it doesn't fit into the unsigned char and gets truncated. Hope this helps!

I tried implementing the variable store function to switch groups in a keyboard layout I developed, only for them to fail to implement in real use. To give you an idea, I'll write the gist of it in pseudocode
begin group(main)
group(main)
store(mode) 'off'
if(mode='off') > use(off)
if(mode='on') > use(on)
group(on) using keys
'+ {key} > set(mode='off')
group(off) using keys
{key} > set(mode='on')
Now When I implemented this on my computer after I reset said computer, I found it wouldn't actually use the different group when I actually installed the keyboard. Stranger yet, when I used the save function to save the variable stores, It cause the keyboard and whatever app I was using it in, to crash.
I did a bit of looking and found that my antivirus program (MCafee livesafe) was quarantining the crashpad_handler.exe files in the keyman installation folders. So after getting them back in my system and repairing the installation, I thought that would solve the problem, but it didn't.
Anybody else experiencing this? What did you do to solve it? For reference, everything was working fine before I reset my PC.
I am trying to get started using Haskell's Euterpea library. My first goal was to get it to play a given sound file (e.g. mp3 or wav), but first I ran into an issue following instructions to get it to just play a simple note sound in ghci.
Following the "Setting up MIDI" instructions at Euterpea's web page, I ran
import Euterpea
play $ c 4 qn
in ghci. The 'play' command resulted in the following error message:
Prelude Euterpea> play $ c 4 qn
*** Exception: No MIDI output device found
CallStack (from HasCallStack):
error, called at ./Euterpea/IO/MIDI/MidiIO.lhs:122:18 in Euterpea-2.0.2-Iz37iWlkpjn2emP4FnvOI1:Euterpea.IO.MIDI.MidiIO
I thought I needed to specify midi output to my machine (macOS Sierra) and found an application called 'Audio MIDI Setup', but it showed that a midi output (my internal speakers) was already specified.
Anyone know what this issue is or how to fix it?
Perhaps you solved this, but for posterity some ideas:
Sounds like you didn't install and run a MIDI synth (e.g. SimpleSynth) first. AFAICT, Audio MIDI Setup doesn't actually include a software synthesizer, it's more for advanced / hardware MIDI setup.
This should create the MIDI output devices that Euterpea couldn't find there. You may also need to play around with channels (e.g. use playDev n instead of play and work out a value for n from your device list... or even just try 1 through 8)
Either way there's some good Mac-focussed help on Donya's working with MIDI on Mac OS X page. Hope that helps.
I would like to know, how would I, in Python, be able to ignore certain/all keypresses by the user while a certain function in the program is executing? Cross platform solutions are preferred, but if that is not possible, then I need to know how to do this on Macintosh. Any help is greatly appreciated! :)
EDIT: Right now, I am processing keypresses through the turtle module's onkey() function since I did create a program using turtle. I hope this helps avoid any confusion, and again, any help is greatly appreciated! :)
You might want to modify your question to show how you're currently processing key-presses. For example is this a command-line program and you're using curses?
You could use os.uname to return the os information or sys.platform, if that isn't available. The Python documentation for sys.platform indicates that 'darwin' is returned for OSX apple machines.
If the platform is darwin then you could, in your code, ignore whatever key-presses you want to.
Edit (Update due to changed question):
If you want to ignore key-presses when a certain function is being called you could either use a lock to stop the key-press function call and your particular function being executed together.
Here is an example of using a lock, this may not run, but it should give you a rough idea of what's required.
import _thread
a_lock = _thread.allocate_lock()
def certainFunction():
with a_lock:
print("Here's the code that you don't want to execute at the same time as onSpecificKeyCall()")
def onSpecificKeyCall():
with a_lock:
print("Here's the code that you don't want to execute at the same time as certainFunction()")
Or, depending on the circumstances, when the function which you don't want interrupting with a key press is called, you could call onkey() again, with the specific key to ignore, to call to a function that doesn't do anything. When your particular function has finished, you could call onkey() again to bind the key press to the function that processes the input.
I found similar problems, maybe it will help you with your problem:
globally capture, ignore and send keyevents with python xlib, recognize fake input
How do I 'lock the keyboard' to prevent any more keypresses being sent on X11/Linux/Gnome?

I have a tx6s-8035 SoC which we integrated into a custom board. We connected an Asix 88772B to the usbotg port and we need it to start in host mode.
We grounded the USBOTG_ID pin and we tought it will start in host mode. It didn't happen unfortunately.
I have investigated the issue and I see a strange behaviour... I wrote dr_mode = host as an extra property into the official device-tree. After that I modified the ci_hdrc_imx driver to print what it got in the device_node and it said "peripheral". I backtraced the problem and when the of_usb_get_dr_mode() function is being invoked the device-tree already contains dr_mode = peripheral.
Any ideas? I just can't imagine what happens there...
p.s.: I double-checked that I'm updating the device-tree in a proper manner.
I found the issue:
The u-boot overrides the 'dr_mode' property with it's 'usbotg' parameter so I had to change the environment variable in u-boot and it works since that.
Maybe it helps others too.
I am using visual studio 2008 and MFC. I accept arguments using a subclass of CCommandLineInfo and overriding ParseParam().
Now I want to pass these arguments to the application while running. For example "test.exe /start" and then to type in the console "test.exe /initialize" to be initialized again.
is there any way to do that?
Edit 1: Some clarifications. My program starts with "test.exe /start". I want to type "test.exe /initialize" and initialize the one and only running process (without closing/opening). And by initialize I mean to read a different XML file, to change some values of the interface and other things.
I cannot think of an easy way to accomplish what you're asking about.
However, you could develop your application to specifically receive commands, and given those commands take any actions you wanted based upon receiving them. Since you're already using MFC, you can do this rather easily. Create a Window (HWND) for your application and register it. It doesn't have to be visible (this won't necessarily make you application a GUI application). Implement a WndProc, and define specific messages that you will receive based on WM_USER + <xxx>.
First and obvious question is why you want to have threads, instead of processes.
You may use GetCommandLine and CommandLineToArgvW to get the fully formatted command line. Detect the arguments, and the call CreateProcess or ShellExecute passing /watever to spawn the process. You may also want to use GetModuleBaseName to get the name of your own EXE.
