PICAXE-28X2 SHIELD BASE (AXE401)
1.0 Introduction
Thank you for purchasing this PICAXE shield base. This
datasheet is designed to give a brief introduction to how the
shield base is assembled, used and configured.
For general tutorials and details on how to use the PICAXE
programming language, please see the PICAXE website and
PICAXE manuals www.picaxe.co.uk The completely free
programming software may also be downloaded from this
website. For individual project advice, and examples of how to
connect your shield base to many different shields and electronic
components, please consider joining the friendly online PICAXE
community at www.picaxeforum.co.uk
A ‘wiki’ of how to use the PICAXE shield base with a wide range
of shields is currently being developed at the PICAXE website.
1.1 Overview
The PICAXE shield base is an open-source hardware ‘arduino inspired’ controller board, designed to
enable PICAXE use of the multiple different ‘shields’ that are now available. The shield base has been very
carefully designed to be compatible with the vast majority of existing shields. Each PICAXE shield base is
also provided with a free of charge AXE405 prototyping shield PCB for experimentation.
The PCB designs are released as ‘open-source’ and ‘not for profit’ designs.

AXE401 PICAXE-28X2 Shield Base
6.0 Programming the PICAXE
The PICAXE uses a ‘BASIC’ style interpreted language,
which is often considered easier to use than the ‘C’ or
‘assembler’ programming languages. Of course if you are a
commercial programmer by profession using ‘C’ may be no
problem to you, but for many school students, hobbyists
or artists starting out with no prior programming
experience the ‘C’ language can sometimes prove difficult
to use (and, in particular, fault find and debug). BASIC
does not have these restrictions as it is designed to be
simpler to use for beginners. However this does not mean
that the BASIC language is not powerful - as complex
programs can also be easily constructed, particularly with
the simple to use in-built BASIC commands for interfacing
protocols such as RS232, 1-wire, I2c and SPI.
PICAXE software is available as the ‘Programming Editor’
for Windows and ‘AXEpad’ for Mac and for Linux. All three
titles are completely free to download and use. If you prefer
to program in a different third party editor (e.g. Kate on
Linux), free command line compilers are also available for
all 3 computer platforms.
PICAXE can also be programmed ‘graphically’ in various other software applications
such as flowcharts (e.g. the Logicator software) and graphical ‘Scratch’ icon based
systems.
6.1 Can I on-screen simulate PICAXE programs?
The free Programming Editor software supports a full on-screen simulation of the
PICAXE program, so that the program can be stepped through line by line an
analysed step by step. Breakpoints can also be set to stop the program at any point.
A special ‘#sim shield’ directive allows the on screen layout to match the pinout of
the shield.
Another piece of software, PICAXE VSM, is a full featured SPICE and digital circuit
simulator that supports circuit simulations. Through on screen animations you can
see, for instance, LEDs light up when you flick a simulated switch or change a light
level.
