Re: Importing questions

Two things to add here: 1) "import wx" does not necessarily mean there is a file called wx.py. It is possible to turn a folder into a python package by including an "__init__.py" file within the folder. I've not used wx so I can't say if that's the case here. 2) Modules/Packages are often located in...

Re: Lunchbox Internet Radio Guide

This is really smart! I'm doing something similar in that I have a Pi, display, speaker and buttons which I plan to put in a lunch box however the buttons will just trigger various train related sounds for my son to use when playing with his toys. All the electronics work nicely, I'm just wondering ...

Re: Help needed: Using GPIO to switch off amplifier circuit

mahjongg, Just wanted to say thanks for your help. I've got the amp and speaker wired up and they're working very nicely. I've also set up pygame such that it mutes the speaker by changing the state of a GPIO pin any time there's nothing playing. All I need to do now is get all this mounted in a box...

Re: Just playing half the sound

Does the audio work in a different programme? I.e. are you sure this is a software problem rather than hardware?

Re: Just playing half the sound

That's strange. I've used pygame to play audio out of the analog jack without any issues. I'll see if I can dig up my code later.

One question, are you using python 2 or 3?

Re: Help needed: Using GPIO to switch off amplifier circuit

Thanks Mahjongg - that makes some sense to me. I assume the fact that the Pi would be putting 3.3v to the shutdown pins even though they're already pulled high wouldn't have any detrimental impact on anything. EDIT: Also, if I'm using this in Mono mode can I just tie one output to ground by linking ...

Thanks both for the quick replies. mahjongg, humour me please: There is a manual that says: "You can turn off the amplifier for each channel separately. To turn off the right channel, connect SDR to ground. To turn off the left channel, connect SDL to ground. By default these pins have pullups to VD...

Help needed: Using GPIO to switch off amplifier circuit

I'm completely new to the creating-a-hardware-project-from-scratch aspect of the Pi but I'm quite excited by the prospect of building something for my son that I think he'll really love playing with (involving buttons, sounds and flashing lights - what's not to love?!) In respect of the sound, I was...

Re: Python loop script stops running: why?

Don't think this would cause an error, but I think the line

should be

Code: Select all

s.ehlo()
Also, do you need that line twice?

Re: How do I run a script many times with out re-programming

I assume you've got a limited number of commands. You probably just want to do something in a "while" loop and break the loop if you receive a certain command. e.g. finished = False while not finished: command = raw_input("Enter command: ") if command == "exit": finished = True elif command == "prin...

Re: Execute python code through Web

The python script would, I think, need to run with superuser privileges as the OP wants to access GPIO. I suspect it's possible to do this with CGI but might get a little bit complicated.

Re: Raspberry Pi 20x4 + Camera

I've no idea what this code does, but the last set of "if" statements looks a bit odd. I think you mean to use "elif" rather than "if". i.e. if Kameros_Kokybes_Indeksas is HD1080 it then sets this to HD720 but then, instead of exiting the "if" block, you start a new one and the "HD720" condition is ...

Re: editing index.html in webiopi

I think the "out" means you want to be able to to control the state of the pin, rather than read it as an input. The issue is whether you want the pin to be initially set high or low. It looks like you can do this by editing the webiopi config file: https://code.google.com/p/webiopi/wiki/CONFIGURATI...
