  • Page 3: Table Of Contents

    The focus of this manual is to describe just the features that are unique to the Micromite eXtreme. For general Micromite programming you should refer to the Micromite User Manual and the Micromite Plus Manual in addition to this manual.

  • Page 4: Introduction

    VGA Output The Micromite eXtreme can drive a VGA display in 640 x 480 pixels or 640 x 400 (widescreen) with eight colours. All the graphics commands and GUI controls available in the Micromite Plus will also work on the VGA output.

  • Page 5: Micromite Family Summary

    The Micromite Family consists of three major types, the standard Micromite, the Micromite Plus and the Micromite eXtreme. All use the same BASIC interpreter and have the same basic capabilities however they differ in the number of I/O pins, the amount of memory, the displays that they support and their intended use.

  • Page 7: Suitable Microcontrollers

    There are two chip sizes (100-pin and 144-pin) with two frequency specifications (200 MHz and 252 MHz). The default clock speed of the Micromite eXtreme is 200 MHz however this can be changed with a configura- tion option to 252 MHz if required. The firmware will automatically adjust for either the 100 or 144 pin version.

  • Page 8: Typical Circuit

    Typical Circuit An example of the required circuit for a Micromite eXtreme is given below: Notes: 1. If the USB module is not used, this pin may be connected to VSS. 2. As an option, instead of a hard-wired connection, an inductor (L1) can be substituted between VDD and AVDD to improve ADC noise rejection.

  • Page 9: Programming The Firmware

    Programming the Firmware Programming the 64, 100 and 144-pin Micromite eXtreme is similar to programming the 28-pin standard Micromite described in the Micromite User Manual. Refer to the following table for the pin connections to a PICkit 3 programmer: 64-pin Micromite...

    These commands only need to be run once as the parameters are stored in non volatile memory. Every time the Micromite is restarted MMBasic will automatically initialise the display ready for use. If the VGA output is no longer required the command OPTION LCDPANEL DISABLE can be used which will disable the VGA feature and return the I/O pins for general use.

  • Page 20: Mouse Support

    Mouse Support The Micromite eXtreme supports a PS2 mouse which will act like a touch input on an LCD screen (it also works with the VGA output). MMBasic will automatically display a mouse pointer on the display which is moved by the mouse. When the left button the mouse is clicked it will act like a touch at the location pointed to by the cursor.

  • Page 21: Unique Micromite Extreme Features

    Unique Micromite eXtreme Features Double Precision Floating Point The Micromite eXtreme uses the hardware floating point capability of the MZ series of chips and can therefore process floating point calculations faster than the Micromite and Micromite Plus. All floating point uses double precision calculations.
