OK. By default I think pygame has 8 channels but I think you can increase this . As for the code, I was just thinking something along the lines of: import pygame.mixer from pygame.mixer import Sound from gpiozero import Button from signal import pause pygame.mixer.init() button_sounds = { Button(21)...

One way to do this would be to make the sound play on a particular channel. You can then use the "get_busy" method of the channel to check if the sound is playing. Your on_pressed method would then call a function that checks if a sound is playing. If it isn't, then it starts it. If it is,...

You don't need to import picamera if you're calling a shell script (whether that is the best way to use the camera is beyond my expertise as I've never used the camera but I'd normally prefer to use python bindings rather than call external scripts). As for your code not starting, you could put some...

Did you just configure the touchscreen in your local config file e.g. ~/.kivy/config.ini ?

You may need to change the global config instead.

elParaguayo

You can try putting this at the very top of your file # -*- coding: utf-8 -*- However, it shouldn't be necessary here and I'm not sure why you're getting that message as there's no obvious stray character in your code. EDIT: I wonder if it's to do with this: /home/pi/t1_'date+%d%m%Y_%H%M-%S'.h264 Ca...

When you define functions, you need a colon at the end of the line:

Code: Select all

def startrecording():

Update your code throughout (and, yes, I missed it when I commented on using subprocess!)

elParaguayo

As above, please make sure your code is in code tags (read the link in PeterO's post). Without it, we lose the indentation and your code will make no sense. Next, when posting about python errors, post the whole error message (which includes line references) so we can home in on the relevant part. T...

Ah. So, it's as easy as:

Code: Select all

sudo pigpiod -t 0

elParaguayo

Thanks. I'll take a look.

I'm having issues configuring ALSA to work with my needs. I have a HiFiberry miniamp and need to configure alsa to work with it. I need software volume control because I'm controlling volume through my code. However, I also need to use ALSA's plugequal equaliser as the sound sounds better that way. ...

elParaguayo

I'm building a radio using the HiFiberry miniamp on i2s, using squeezelite as the player. When pigpiod is active, the music is very slow and, as a result, low. If I disable pigpiod the sound is fine. Is there a way to get pigpiod not to interfere with i2s? Or have I done something wrong?! For what i...

Also, why aren't you using the proper threading module? Isn't the one you're using a dummy module? _thread python 3.5 https://docs.python.org/3.5/library/_thread.html But most user the higher threading https://docs.python.org/3.5/library/threading.html#module-threading I'm no expert in either. Yup,...

I'm not experienced in this sort of project in any way shape or form but if I were doing it, I'd try find a way of monitoring audio levels and triggering an action when a threshold level is exceeded. Distinguishing the cry from other noises will be far too hard. Assuming your baby is in a quiet plac...

Please use code tags when posting code Never used Thonny but have you tried using a small sleep in your loop rather than pass? You could be maxing out your CPU.

Please post in English if possible.

Can you post the line from your crontab.

Also, you probably want the full path to shutdown. I don't remember if it's /usr/bin/shutdown or /usr/sbin/shutdown.

EDIT: I think it's actually /sbin/shutdown

Error message would be a good place to start. Are you sure you've installed the module for python 3? You may think you have installed it but you may have only installed for python 2.

elParaguayo

What's the problem with your code? This line: print('| {0:>6} | {1:>6} | {2:>6} | {3:>6} |'.format(*values)) should work fine as paddyg says. You don't even have to use all the values in the same line. e.g. you can just do: print('| {3:>6} |'.format(*values)) and the line is still valid.

Not quite what you had in mind, but I used Kivy to do some fun stuff on the screen:

Your error message still shows single underscores before and after name.

Sorry, had missed that it was your thread. Why not carry on in that thread if it's directly related?

elParaguayo

Have you seen this thread: viewtopic.php?f=32&t=204627

If your question is different, please provide more information about what you're trying to do.

elParaguayo

OK - so we're getting somewhere.

That error says the gpiozero module isn't installed.

At a command terminal, try:

Code: Select all

sudo apt install python3-gpiozero

and then run your code again.

elParaguayo

That screenshot shows you typing the import command at a terminal prompt. That's not going to work.

The import command needs to be in a python environment so run "python3" from the terminal prompt and then try your import line.

elParaguayo

Doesn't that mean you'd be better posting your question on that github page?
