Simple LF Audio Oscilloscope Using Standard Text Mode Python. (Python)

2011-06-26T21:42:55-07:00

Python recipe 577771 by Barry Walker (anim, audio, demo, display, linux, oscilloscope, scope, sound).

A Linux DEMO to show how to display a waveform using standard text mode Python. The audio device /dev/dsp is used and must be available. Levels are set using the standard audio mixers.

Just feed a signal of say 300Hz to 3KHz, (normal voice spectrum), using say, the internal mic, and watch the waveform appear inside the X-Y graticule.

This method WILL be used for a program proper and may be uploaded to this site in the future.

Read the code for more information.

This code is Public Domain and you may do with it as you please.

SimpleTron3x.py "Game" To DEMO XY Drawing Using The Keyboard In Standard Text Mode Python. (Python)

2011-05-29T14:28:19-07:00

Python recipe 577728 by Barry Walker (anim, demo, display, game, linux).

SimpleTron3x.py.

This code is a FUN program only to DEMO how to draw in a text mode Python shell.

There is an inkey() "function" extracted from a "class" recipe on this site. See code for more information.

This was tested on PCLinuxOS 2009 with Python 3.0.x and Debian 6.0.0 with Python 3.1.x.

This ASSUMES an 80 x 24 Python shell window.

Issued as Public Domain, you may do as you like with this code.

Simple LF Audio Oscilloscope Using Standard Python. (Python)

2011-04-07T17:17:57-07:00

Python recipe 577644 by Barry Walker (anim, audio, demo, display, linux, oscilloscope, scope, sound).

AudioScope.py

I think this might be a first for both Python.

Initially uploaded to LXF, now also here under the MIT licence.

I am building a kids level seismometer and wanted to use standard Python inside Linux.

This DEMO code was my starter idea and looks as though using standard ASCII only might just work a real treat.

I've issued it to LXF under the MIT licence for future reasons.

It doesn't look much on screen except that the waveform(s) shown is/are a basic visual, electrical representation of your voice. ;o)

It is possible to link the earphone socket on this notebook to the mic input and start the Audio Function Generator, elsewhere in this site, in a separate Python terminal and see those waveforms inside the AudioScope.py`s own Python terminal.

This grabs a 1 second 8KB burst, and then displays it onto the Python terminal. The timebase, amplitude, trigger, single shot and others are not included but the main grab and display using /dev/dsp is shown. This can be made platform independent by changing the /dev/dsp to something external like the Arduino Dev Board. This uses STANDARD Python 2.5.x and later and tested on PCLinuxOS 2009 and Debian 6.0.0.

DUAL 4 Bit Vertical Coloured Analogue Bar Graph Generator DEMO... (Python)

2011-05-04T17:58:08-07:00

Python recipe 577685 by Barry Walker (analogue, anim, audio, bargraph, color, colour, demo, display, linux).

This is a two channel version of the "Four Bit Vertical Coloured Analogue Bar Graph Generator DEMO...".

These are DUAL LED style "VU" meters in the vertical plane...

This is for standard Python 3.x.x.

It has different overload beeps for each channel, and has all the unwanted code has been removed.

It demonstrates how to obtain multichannel ability, (it is possible to add more channels).

Seven Bit Colored Analogue Bar Graph Generator DEMO... (Python)

2011-03-17T22:14:52-07:00

Python recipe 577612 by Barry Walker (analogue, anim, audio, bargraph, color, colour, demo, display, linux). Revision 3.

..For STANDARD Python 2.6 and above...

This code will display a horizontal full colour analogue "VU" style meter. It displays green for normal, yellow for warning and red for danger with a critical error beep near the end of full scale, at value 120+.

This version is for Python 2.6 and above and only for the Linux, (*nix?), platform.

It is an "at a glance" display that is in colour rather than having to read say a digitally generated number.

A Python 3.x version can be found here:-

http://www.linuxformat.com/forums/viewtopic.php?t=13443

This has uses "for at a glance" voltmeters, ammeters, data-loggers, anemometers etc, etc...

Watch for wordwrapping etc...

Four Bit Vertical Coloured Analogue Bar Graph Generator DEMO... (Python)

2011-04-23T20:50:55-07:00

Python recipe 577675 by Barry Walker (analogue, anim, audio, bargraph, color, colour, demo, display, linux).

This is a(n) LED style "VU" meter in the vertical plane instead of the horizontal one in the recipe below:-

http://code.activestate.com/recipes/577612-seven-bit-colored-analogue-bar-graph-generator-dem/?in=lang-python

It is another "AT A GLANCE" display with an overload error beep too.

This is for Linux only and tested on Python 2.6.x although it should work on earlier 2.x.x versions.

A Python 3.x.x version can be found here:-

Clear screen and beep for various platforms. (Python)

2011-02-26T14:26:02-08:00

Python recipe 577588 by Barry Walker (amiga, audio, beep, clearscreen, display, error_beep, error_sound, e_uae, linux, screenclear, sound, windows, winuae).

This little module gives a clear screen and beep for the classic AMIGA, WinUAE, Windows and Linux all in CLI/Command-Prompt/Terminal mode.

It works from Python 1.4.x to 2.7.x; talk about backwards compatibility... ;oD With very little modification it will work on Python 3.x.x easily.)

See the file clsbeep.py attached for more information.

it is saved as clsbeep.py and placed into the Python - Lib drawer or where-ever the modules are located and called as a module:-

>>> import clsbeep

Its usage is:-

clsbeep.cls() and clears the screen. clsbeep.beep() and creates an error beep. clsbeep.both() creates an error beep first then clears the screen.

It is Public Domain and if you modify it to suit other platforms please let me have a copy of your code... :)

Simple analogue anim and digital voltmeter with alarm DEMO... (Python)

2011-03-04T19:47:37-08:00

Python recipe 577596 by Barry Walker (amiga, analogue, anim, audio, demo, digital, display, e_uae, linux, voltmeter, windows, winuae).

I needed a simple standard Python analogue and digital display along with an overload beep when used as a basic voltmeter.

Analogue readout, for quick glance. Digital readout, for better accuracy. Beep, to warn me of impending doom... ;o)

This was my starter code and works from Python 1.4.x to 2.7.x on MINIMUM platforms, AMIGA A1200, MS Windows ME and Knoppix 5.1.1. It is a stand alone program and the easiest way to start it is to import it as though it is a module.

(I DO have a Python 3.x.x version too and WILL be uploaded here in the future.)

Although this is a DEMO it did access, (home built), HW from various ports on differing platforms.

This module IS needed for it to work:-

http://code.activestate.com/recipes/577588-clear-screen-and-beep-for-various-platforms/?in=lang-python

These simple HW access modes using standard Python code WILL be released in the future.

This DEMO is released as Public Domain and you may modify it as you please...
