General description

The PICmicro development board is designed f or learning PICmicro
programming and for developing PICmicro based projects. The board
allows a wide range of flash PICmicro microcontrollers to be
programmed and executed through the ‘P PP’ software utility supplied.
The board is tightly integrated to our range of software utilities and
courses which provide complete solutions for learning PICmicro
programming at a variety of levels.

The board is shipped with a PIC16F88 – an 18 pin device with up to 15
I/O lines configured in two ports – A and B. The ’88 device is one of the
newer devices from Arizona Microchip and is surprisingly powerful with
on-board A/D, internal clock, internal USART and a host of other
functions and features.

The nature of the PICmicro range of devices is such that 12, 14, 18, 28,
and 40 pin devices are – to some extent – upwards compatible, and the
DIL sockets on the board are therefore be connected in parallel. Onl y
one PICmicro microcontroller should be inserted at any time.

The board has been designed to allow those with little or n o experience
of embedded microcontroller programming to be able to produce highly
functional designs in as short a time as possible. With this in mind we
have included switches on port A and B input/output pins, a quad 7­segment display, a 2 line 16 character alphanumeric display, a choice of
crystal or RC oscillator, simple on-board analogue sensor (light) and
sensor simulator (potentiometer) and the ability to interface the board to
a host of external sensors including motion, temperature, pH. humidity
etc. Ports A and B are also connected to screw terminals on the sides of
the board via 150ohm resistors which protect the device on the board
itself.

The board can be used with ZIF sockets if required: please b ear in mind
that you may need to insert one or more turned pin DIL sockets to raise
the height of some ZIF sockets to clear surrounding components.

Full tutorials in programming the PICmicro in assembly code, C, and
flowcharts are available. These sets of tutorials are available on CD
ROM and require no other software - all compilers and development
environments are included on the CDs themselv es.

Add-on options

There are a range of more than 70 add-ons for this board which allow
you to customize it to form the basis of a superb educational or
development solution:

Sensors

There are over 30 sensors – ranging from sim pl e temperature probes to
heart rate monitors – that can be plugged into the two white sensor
sockets. A full list is given below. There are several different types of
sensor and for educational use we recommend that you select a range of
sensors with different characteristics and coding techniq ues as follows:

Sensor Output/action Coding strateg y
Temperature probe Simple potential divider A/D conversion, calibration, value look

Motion detector Gives out a digital pulse

Heart rate monitor Gives out an analogue voltage

Photogate and pulley
wheel

correlati ng to distance

pulse
When IR light path is

interrupted, digital output
changes

up, display

Pulse time measurement, conversion
display

Data slicing, timing,

Various

For added security the development

board can be mounted on a rugged

metal platform….

…which can be locked down to a

bench with a Kensington lock….

….the resulting assembly can be fitted

into our high quality plastic trays for

..and these trays are compatible with a

range of furniture and trolleys for

storage and classroom use.
