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...

Python recipe 580750 by Barry Walker (amiga, apple, demo, echo, fs_uae, linux, printf, unix, windows, winuae).

A simple example of having a pseudo-echo using sys.stdout.write...

This gives exactly the same results from Python Versions, 1.4.0, 2.0.1, 2.5.6, 2.6.9, 3.4.3 and 3.5.2 on various platforms including the classic AMIGA A1200.

A simple raw hexdumper. (Python)

2016-09-19T13:24:37-07:00

Python recipe 580697 by Barry Walker (amiga, apple, fs_uae, hex, hexdump, linux, macbook_pro, raw_hexdump, unix, windows, winuae).

This is not a hexreader. This code creates a raw hexdump of a binary file that is whitespace, optional, delimited. The dump is saved into the current directory with a ".hex" extension.

It works on just about any current platform but is designed around a stock Amiga A1200(HD) with Python 1.4.0. It also works on the current stable version 3.5.2.

I needed a hexdump some years ago for banging the Amiga hardware, and decided to modify recently for another usage but it had to still work on version 1.4.0 for the classic A1200.

Colo(u)rs Inside Text Mode Python... (Python)

2012-08-21T21:01:57-07:00

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......

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...

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......

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...

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...

The test code for the Arduino Diecimila Dev Board is here:-

For AMIGA-Heads Only. PAR: As A VOLUME In READ Mode Only. (Python)

2011-06-12T16:34:12-07:00

Python recipe 577750 by Barry Walker (amiga, demo, parallel, parallel_port, port, read).

PAR: as a VOLUME in READ mode using Python 1.4 onwards on Classic AMIGAs...

Many years ago Irmen de Jong ported Python to the Classic AMIGA range of computers, (many thanks Irmen for your time in doing so). The versions were at least 1.4.x to 2.0.1 and now someone else has included version 2.4.6.

This gives we lowly users of the AMIGA at least a chance to see and use Python in some guise or another. This code shows how to access the AMIGA parallel port for 8 bit READ only. This is so that ADCs could be attached to the port, read by Python code EASILY and utilised as a Data Logger/Transient Recorder, as just one example.

There needs to be a single HW WIRE link only from the 23 way video port to the 25 way parallel port for this to work. See the archive......

http://aminet.net/package/docs/hard/PAR_READ

......on how to set about this extremely simple task.

NO knowledge of the parallel port programming is needed at all to grab 8 bit data from it using Python and other languages; (ARexx is used in the archive above).

There is a flaw, NOTE:- NOT A BUG!, in the Python code but for this DEMO it is ignored. ;o)

I'll let all you big guns work out what it is; you will need a good working knowledge of the Classic AMIGA.

Arduino Diecimila Board Access Inside WinUAE DEMO. (Python)

2011-03-26T14:30:31-07:00

Python recipe 577625 by Barry Walker (access, amiga, arduino, demo, winuae). Revision 2.

This is one of a few Arduino Python snippets to come your way. This one is DEDICATED entirely to the classic stock AMIGA A1200HD emulation inside WinUAE. With a small hardware modification it WILL work on a genuine stock AMIGA A1200HD also see inside the code for more information.

It only requires an ancient version of SATNDARD Python 1.4.x as an absolute minimum, and yes I know it is ancient, but hey, the classic AMIGA is still capable of running Python to version 2.0.x; other AMIGA variants can run much newer versions.

Certain assumptions have been made and are inside the code.

Also in the code box is the very basic Test.pde file to program the Arduino Diecimila Board with so that this works.

There will be Linux and Windows versions coming that require only STANDARD Python also - NO pySerial is required AT ALL.

Sorry but you will need to split the two pieces of code below manually...

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...
