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.

This DEMO displays the action of an EM87 Magic Eye tuning indicator using a standard Python 2.6.x or greater install. It is for at least Windows Vista 32 Bit and at least Debian Linux 6.0.0.

It is for FUN only and shows how to generate yet another analogue display using a default text mode install.

With careful thought and viewing between Code Page 850, (Windows Vista onwards), and Code Page 437, (EFFECTIVELY Linux), one can pick the "graphics" characters to generate some interesting old style text mode displays on screen.

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).

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

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.

Arduino-Windows2x.py

Finally the Windows 32 bit version of the other recipes of similar design. (The AMIGA/WinUAE and Linux versions are already on this site.)

To get more recognisable characters displayed it is best to use a potentiometer wired as one end to +5V, the other end to Gnd and the wiper to ANALOG IN 0. This has been tested on various Linux Distros and kept as simple as possible so that anyone can understand it.

The required ?.pde file for the Arduino Board can be found here:-

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.

Arduino-Linux2x.py

This is a simple Python example of accessing a(n) Arduino Diecimila Board using Standard Python 2.x.x.

This code requires NO PySerial to work, just standard Linux(/Unix?) commands and a Standard Python install.

The only prerequisite is that a root terminal is needed to start Python in.

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

To get more values displayed it is best to use a potentiometer wired as one end to +5V, the other end to Gnd and the wiper to ANALOG IN 0. This has been tested on various Linux Distros and kept as simple as possible so that anyone can understand it.

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...

..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...

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...

This program was written per R.T.Giles's second assignment in 10COF180 (November 25, 2010). A student under his instruction wanted help writing a program, and while not required, a GUI was placed on the program's output to visually demonstrate what was taking place within the program. The recipe below provides a simple simulation of a undamped pendulum and produces a visual representation for about thirty seconds. The code could be greatly improved but gives a demonstration of what a few turtle commands can do in Python. Very little code must be written to produce graphics on the computer screen.
