Unique
Atmel AT89C2051/4051 project board that greatly simplifies and speeds development
of microcontroller projects and offers a very professional looking instrument
case for the completed project.
Small
prototype PCB with large character 4-digit LCD and professional looking
instrument case. Pre-programmed intelligent LCD driver provides simple
but powerful interface to non-volatile memory, keybutton decoding, math
routines, real-time clock, etc. Complete with RS232 interface, 8051
assembler, working C compiler, BASIC compiler and software examples to
build digital voltmeter and thermometer.

m)
Routines to allow use of front panel keys to view/increment/decrement 8/16
bit variables
EXP-30:
8051
or AVR based development system with intelligent IC simplifies development
and provides professional looking instrument case for finished project.
The
EXP30 development system consists of a development PCB containing dual
microprocessor IC's (flash AT89C4051 and preprogrammed 8051), 4 digit LCD,
three key buttons, piezo alarm buzzer, non volatile EEPROM memory chip,
RS232 communications, software CD and a professional instrument case with
mounting hardware.
A
140 pad scratchpad prototyping area is provided for user circuitry to create
the desired project. Pre etched vertical and horizontal circuit traces
can be cut to create a wide range of options for mounting IC's, resistors,
capacitors, etc. The PCB is solderplated and has a solder mask to help
prevent solder bridges. Spare screw terminals are provided for connections
to external sensors or bring signals out of the instrument. The PCB is
routed to the correct outline to fit snugly into the supplied instrument
case.
The
case is manufactured from UV stable AES plastic and fully waterproof from
the front with a nitrile o'ring. A mounting bracket, bulkhead gasket and
all brass and stainless steel mounting hardware is supplied. The stylish
case fits in a standard 2-1/8" (54mm)diameter hole and has a 7 position
screw terminal block on the back for power, RS232 interface and extra I/O
connections.
The
user programmable AT89C4051 uses two I/O lines to communicate with the
pre-programmed 8051. The 8051 contains a host of powerful routines coded
in fast assembly to handle the complicated and tedious work of driving
the LCD, EEPROM, alarm buzzer, debouncing and decoding key buttons, 32
bit math routines, real-time-clock, extra RAM storage, random number generators
and more. Simple commands to this IC produce sophisticated results such
as converting a binary number to BCD and displaying the results on the
LCD display with a single command. Each segment of the LCD is separately
controllable.
The
socketed Atmel AT89C4051 can be replaced with a pin-compatible AT90S2313
AVR chip. Use the prototyping area for additional components to add circuitry
to build digital voltmeters, timers, data loggers, D/A's, or whatever.
Instructions
and software CD with sample code written in C, BASIC and assembly language
is included. Also included are a working C compiler, BASIC compiler and
8051 assembler. Instructions and software is included for sample projects
to build a digital voltmeter, thermometer and digital clock.
