<p>...that can be played using almost ANY audio player available.</p>
<p>This simple snippet of code generates a 1 second sinewave WAVE file.
It IS saved inside the CURRENT drawer so that you can find it... ;o)</p>
<p>This works on:-
Classic stock AMIGA A1200, using Python 1.4.0.
WinUAE and E-UAE, AmigaOS 3.0.x using Python 1.4.0 to 2.0.1.
Windows, to at least 7, using Python 2.0.1 to 3.3.2.
Various Linux flavours using Python 2.4.6 to 3.2.2.
Apple OSX 10.7.x and above using Python 2.5.6 to 3.4.1.</p>
<p>The file size is 8044 bytes and _IF_ you need to it can be palyed directly
without a player on some Linux flavours that have the /dev/dsp device.
It is an 8 bit, unsigned integer, mono, 8000Hz sampling speed 8000 byte
RAW file with the WAVE header added.</p>
<p>It will still work with PulseAudio and OSS using...</p>
<p>cat /full/path/to/beep.wav > /dev/dsp</p>
<p>...but with a momenatry click due to the 44 header bytes; but hey it is
a beep alternative...</p>

<p>ANSI _Esc_ codes here:- <a href="http://www.termsys.demon.co.uk/vtansi.htm" rel="nofollow">http://www.termsys.demon.co.uk/vtansi.htm</a></p>
<p>There are only three important things from the ANSI _Esc_ codes that are needed to obtain a neat finish to a program written in standard text mode Python:-</p>
<p>1) Clearing the screen. (Already done without the dedicated ANSI _Esc_ code!)</p>
<p>2) Colours and other character attributes. (Already done!)</p>
<p>3) A forced printing of a character or string from a given location inside the Terminal window.</p>
<p>To clear the screen does NOT require another dedicated ANSI _Esc_ code, (although it exists). This code uses the print("\r\n") method which works in all cases coupled with the one function supplied......</p>

<p>(It MIGHT work on AMIGA OS3.5x and 3.9x with Python 2.4.6, but totally untested and I hold no responsibility for the outcome when trying it.)</p>
<p>It is a DEMO to poke a byte inside _ANY_ memory address inside the standard CPU 68EC020 16MB boundary.</p>
<p>This is not a function nor a class but just a DEMO to show how to write directly to HW, (or memory), addresses.</p>
<p>POKING memory or hardware addresses is not recommended for novices without studying the machine first, and, this code will ignore any _ENFORCER_hits_.</p>
<p>I experimented with this several years ago and have decided to finally release it. I do await the flak!</p>

<p>No comments about the use of "eval()" as Python Version 1.4.0 does not

Revision 2.
</p>
<p>This code is kids level Analogue Data-Logger(/Transient-Recorder), using the Arduino series of dev' boards.</p>
<p>It is no where near completion and is a second feeder/feeler upload only.</p>
<p>It is designed to work from Classic Text Mode Python from Versions 1.4.0 to 2.7.2 on a Classic AMIGA, WinUAE, Linux and Windows, (32 bit), to Vista.
Not tested on Python for Windows 7, (32 bit), nor Mac OSX flavours as I don't have these OSes.</p>
<p>Linux versions run from a default root terminal for the time being.</p>
<p>The Arduino dev' board IS catered for in the code for the above platforms just thoroughly read the code for more information. It defaults to a DEMO mode so you can see it working...</p>
<p>The test code for the Arduino Diecimila Dev Board is here:-</p>

</p>
<p>This little module gives a clear screen and beep for the classic AMIGA, WinUAE, Windows and Linux all in
CLI/Command-Prompt/Terminal mode.</p>
<p>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.)</p>
<p>See the file clsbeep.py attached for more information.</p>
<p>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:-</p>
<pre class="prettyprint"><code>>>> import clsbeep
</code></pre>
<p>Its usage is:-</p>
<p>clsbeep.cls() and clears the screen.
clsbeep.beep() and creates an error beep.
clsbeep.both() creates an error beep first then clears the screen.</p>
<p>It is Public Domain and if you modify it to suit other platforms please let me have a copy of your code... :)</p>

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

</p>
<p>I needed a simple standard Python analogue and digital display along with an overload beep when used as a
basic voltmeter.</p>
<p>Analogue readout, for quick glance.
Digital readout, for better accuracy.
Beep, to warn me of impending doom... ;o)</p>
<p>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.</p>
<p>(I DO have a Python 3.x.x version too and WILL be uploaded here in the future.)</p>
<p>Although this is a DEMO it did access, (home built), HW from various ports on differing platforms.</p>
<p>This module IS needed for it to work:-</p>

<p>These simple HW access modes using standard Python code WILL be released in the future.</p>
<p>This DEMO is released as Public Domain and you may modify it as you please...</p>

<p>Iterates through a directory, reading the EXIF data from each jpg/jpeg file.
Parses the date/time from EXIF data and:</p>
<ol>
<li>if it differs from file modification date/time then changes file date/time</li>
<li>moves file to <code>YYYY/YYYY_MM_DD</code> directory</li>
