    The Micromite


    The Micromite is a Microchip PIC32 microcontroller programmed with the free MMBasic firmware. These chips cost from $4 to $10 and are available in packages from 28 pins to 100 pins. When programmed with the Micromite firmware they make a powerful and easy to program microcontroller that is ideal for most hobby projects.

    MMBasic is a Microsoft BASIC compatible implementation of the BASIC language with floating point, integer and string variables, arrays, long variable names, a built in program editor and many other features.

    Using MMBasic you can use communications protocols, measure voltages, detect digital inputs and drive output pins.  Special features include the ability to use touch sensitive LCD displays, temperature sensors, distance sensors and more.

    You can use the Micromite as the intelligence inside any project that requires a medium speed microcontroller but without the hassle of programming in a complex language.

    There are a two varients of the Micromite and many PCB boards and projects based on it.  This page serves as a summary page for all of them, from here you can branch off to subsiduary web pages that describe each in detail. 

    At the bottom of this page you can download the manuals and firmware for all versions.

    Micromite Microcontroller Chips

    The Micromite is available in two versions: 

    Micromite Explore 64 and Explore 100

    The Micromite Plus is supported with two PC boards.

    Micromite LCD Backpack

    This is a printed circuit board designed to piggyback on a standard 2.4" or 2.8" touch sensitive LCD panel.  It has less than a dozen components and can be built in half an hour.

    The combination of the Micromite with the colour LCD panel provides an amazing amount of power for less than US$25.  The 320x240 pixel LCD can display colourful text and graphics and the touch sensitive input means that many manual knobs and switches can be replaced with on screen graphics.  The eleven I/O pins can be used to measure temperature, distance, voltages, etc and under control of your BASIC program turn on lights, relays and other output devices.

    Micromite Based Projects

    This website hosts four projects based on the Micromite LCD Backpack.   They are:

    Getting Started with the Micromite

    The Micromite is quite a sophisticated device, it is an almost complete computer with its own programming language and for newcomers there is a lot to learn. 

    The book Getting Started with the Micromite is a tutorial that assumes that the reader has had minimal exposure to microcontrollers and the BASIC programming language in particular.  It starts with choosing the microcontroller, how to program the Micromite firmware into it and how to connect to the console.  It then presents a beginners course in BASIC programming and moves onto some of the more specialised aspects of the Micromite including input/output, embedded features and communications protocols.

    It is recommended reading for anyone who is new to the Micromite and can be downloaded from the download section at the bottom of this web page.

    A website that sells the 44-pin version of the Micromite MkII, Micromite chips and all sorts of support parts:

    The Back Shed forum is a great place to hang out and discuss the Micromite and microcontrollers:

    Micromite and MMBasic Support

    The first thing that you should read is the Micromite Frequently Asked Questions (FAQ) list as this covers hints related to usage and programming.  The list is rather short at this time but as more questions arise it will be expanded.

    Also, you should check the list of current bugs found in the Micromite version of MMBasic as it lists any faults found in the current version and provides workarounds if applicable.

    The Back Shed has an active forum where many knowledgeable users are happy to help newcomers to the Micromite and MMBasic: http://www.thebackshed.com/forum/Microcontrollers

    Source Code to MMBasic

    The complete source code for the Micromite version of MMBasic is available for personal use at the main MMBasic website at http://mmbasic.com.

    Firmware Updates

    A new versions of MMBasic (ver 5.05.01) for the Micromite, Micromite Plus and Windows/DOS is available and can be downloaded from the download area at bottom of this page. Compared to V5.04.09 this fixes a number of bugs and introduces some new features including multicolour analogue gauge controls for the Micromite Plus.

    One of the bugs fixed in this release could cause out of memory errors when string expressions were used in the parameter list of user defined subroutines and functions. This was a serious bug and for this reason it is recommended that systems using V5.04.09 be upgraded to this version.

    To load the new version you will need a PIC32 programmer.  The best (and cheapest) programmer is the PICKit 3 by Microchip.   Prices range from US$20 for a clone and it is easy to update the firmware - see this page for a tutorial. You can also build the Microbridge which is a very low cost PIC32 programmer - see this page for the details.
