A Function To Create A 1 Second Sinewave WAVE Beep File. (Python)

2014-11-23T19:24:46-08:00

Python recipe 578971 by Barry Walker (amiga, apple, audio, beep, error_beep, error_sound, e_uae, linux, sinewave, sound, wav, wave, windows, winuae).

sinebeep.py

Creating an audio file called...

beep.wav

...that can be played using almost ANY audio player available.

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)

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.

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.

It will still work with PulseAudio and OSS using...

cat /full/path/to/beep.wav > /dev/dsp

...but with a momenatry click due to the 44 header bytes; but hey it is a beep alternative...

Well the Python version of the top URL has been uploaded to AMINET on 01-08-2013...

Now the big gun that complained about my fun Python upload and voted it down can see that this was a serious attempt ae viewing "Hello World!" in extra large xharacters.

This is the result in Python...

It is ONLY uploaded to AMINET and that is where it will stay.

If you want it then use the pointer inside code section.

Remember to change the BIG_TIME.py.txt file on AMINET to BIG_TIME.py...

Designed around a Macbook Pro OSX 10.7.5 for the Classic AMIGA platforms and works on Debian 6.0.x and PCLiuxOS 2009 using Python versions 1.4.0 to 3.3.2 inclusive...

Although the description in the AMINET readme below is for an AMIGA environment it does not take a genius to adapt it to the other platforms...

Boy was this difficult to get working in a single Python script...

ENJOY...

This is the AMINET readme file:-

Short: A Big Digital Clock Python Script. Author: wisecracker@tesco.net (Barry Walker) Uploader: wisecracker@tesco.net (Barry Walker) Type: dev/src Version: 1.00.00 Architecture: generic; m68k-amigaos

Distribution: Public Domain, Emailware.

============================================================================

Architectures: Classic AMIGAs, E-UAE and WinUAE.

MINIMUM Requirements Are:-

    68EC020 CPU and 2MB RAM total, example, a standard A1200(HD).
    WinUAE Version 1.5.3 minimum. 
    Standard OS3.0x install or better.
    Python Version 1.4.0 or higher.
    (Also, OSX 10.7.5, Debian Linux 6.0.x and PCLinuxOS 2009.)

History.

01-08-2013. Version 1.00.00:- Original upload to AMINET...

This is dedicated entirely to the AMIGA community and AMINET and will not be uploaded elsewhere.

To install just download the "BIG_TIME.py.txt" file and rename it to "BIG_TIME.py" without the quotes. Drag this file into your AMIGA PYTHON: volume and...

From a minimum of Python Version 1.4.0 prompt:-

>>> exec(open("PYTHON:BIG_TIME.py").read())<CR>

And away you go...

This code is/was designed to work in all versions of Python from 1.4.0 to 3.3.2 on at least the platforms shown in the Architectures: section.

It was developed entirely on a Macbook Pro OSX 10.7.5 and finalised using MEmacs for the AMIGA.

This is just a simple DEMO to show how to generate large digits in Python and put them to use as an _AT_A_GLANCE_ digital clock.

It starts up by generating all of the characters available for the DEMO for five seconds then goes into the clock proper.

As this code is multi platform AND multi Python version then it is issued as GPL2...

Position The Cursor Almost Anywhere Inside Standard Text Mode Python Terminal. (Python)

2012-06-17T17:10:29-07:00

Python recipe 578167 by Barry Walker (amiga, apple, cursor, demo, e_uae, linux, locate, macbook_pro, winuae).

A DEMO showing the power of the ANSI (ASCII) _Esc_ codes in standard text mode Python.

ANSI _Esc_ codes here:- http://www.termsys.demon.co.uk/vtansi.htm

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:-

1) Clearing the screen. (Already done without the dedicated ANSI _Esc_ code!)

2) Colours and other character attributes. (Already done!)

3) A forced printing of a character or string from a given location inside the Terminal window.

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......

For AMIGA-Heads Only. Poking A HW, (Memory), Address On A Classic AMIGA, Inside Text Mode Python. (Python)

2012-09-09T19:25:00-07:00

Python recipe 578255 by Barry Walker (amiga, demo, e_uae, hardware, memory, poke, winuae).

For AMIGA-Heads Only...

This code is purely for a minimum of a stock Classic AMIGA A1200(HD), E-UAE, and WinUAE running AMIGA OS3.0x to 3.1x. It will NOT work on any other platform!

(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.)

It is a DEMO to poke a byte inside _ANY_ memory address inside the standard CPU 68EC020 16MB boundary.

This is not a function nor a class but just a DEMO to show how to write directly to HW, (or memory), addresses.

POKING memory or hardware addresses is not recommended for novices without studying the machine first, and, this code will ignore any _ENFORCER_hits_.

I experimented with this several years ago and have decided to finally release it. I do await the flak!

It works from Python Versions 1.4.0 to 2.0.1 for the classic AMIGA.

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

Ensure that the T: Volume exists on the running machine.

See inside the code and text below it also as to how it works...

Forwards Compatibility; Generating A Function On The Fly... (Python)

2012-06-06T17:16:27-07:00

Python recipe 578160 by Barry Walker (amiga, demo, e_uae, function, generator, linux, windows, winuae).

This code auto-generates a function that converts a string to bytes only in Python Versions 3.x.x. The function will NOT be generated in Python Versions 1.4.0 to 2.7.x. See the code for all the versions tested on. Inside the code are commented-out lines to show a practical usage for this and WILL be used in future /dev/audio or /dev/dsp access that I may develop...

Python recipe 578101 by Barry Walker (amiga, apple, color, colour, demo, display, e_uae, linux, macbook_pro, windows, winuae). Revision 2.

A simple DEMO to show how to enhance Python inside a Terminal. This works on Classic AMIGAs, E-UAE, Debian Linux 6.0.0, PCLinuxOS 2009, Windows XP and Vista and WinUAE, from Python 1.4.0 to 3.3A2.

Due to a complaint about my _fun_ upload recently I decided to post this so that the MANY can now find out how to manipulate text inside a Python Terminal window so that it looks much better.

For AMIGA-Heads Only. Generating An Audio Signal In Text Mode Python. (Python)

2011-11-30T21:23:20-08:00

Python recipe 577971 by Barry Walker (amiga, audio, demo, e_uae, sound, winuae).

This DEMO is not for the big guns. It is aimed at those who still use a minimum of an ancient classic AMIGA A1200(HD), E-UAE, WinUAE, of which there are still a lot of us about...

No comments about the use of "eval()" as Python Version 1.4.0 does not have "int()" and this is designed to work on all versions of Python available for the above platform. See the code for minimum requirements and much more information.

MANY THANKS to Irmen de Jong for porting early versions of Python to the classic AMIGA to give we lowly users a taste of what was/is to come.

This code will probably make the professionals cough a little, but, boy what fun it is to see how powerful Python can be on an open platform like the AMIGA.

Written in such a way that anyone can understand how it works...

I really don't care how you vote this as it is for those, including professionals, who enjoy messing with AMIGA variants purely for fun and relaxation, and, to......

Kids Level Analogue Data Logger, (Transient Recorder), Program. (Python)

2011-07-31T16:14:48-07:00

Python recipe 577796 by Barry Walker (amiga, analogue, anim, apple, arduino, data, demo, display, e_uae, linux, logger, macbook_pro, program, windows, winuae). Revision 2.

This code is kids level Analogue Data-Logger(/Transient-Recorder), using the Arduino series of dev' boards.

It is no where near completion and is a second feeder/feeler upload only.

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.

Linux versions run from a default root terminal for the time being.

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...

Clear screen and beep for various platforms. (Python)

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.
