Introduction

1Introduction to the Rapid Development Kit

This QuickStart provides:

•general information on the PHYTEC phyCORE-ADuC812 Single

Board Computer (SBC)

•an overview of Keil’s µVision2 software evaluation development

tool chain, and

•instructions on how to run example programs on the

phCORE-ADuC812, mounted on the PHYTEC

phyCORE Development Board LD 5V, in conjunction with

µVision2 IDE

Please refer to the phyCORE-ADuC8xx Hardware Manual for

specific information on such board-level features as jumper

configuration, memory mapping and pin layout. Selecting the links on

the electronic version of this document links to the applicable section

of the phCORE-ADuC8xx Hardware Manual.

1.1 Rapid Development Kit Documentation

This “Rapid Development Kit” (RDK) includes the following

electronic documentation on the enclosed “PHYTEC Spectrum

CD-ROM”:

•the PHYTEC phyCORE-ADuC8xx Hardware Manual and

phyCORE Development Board LD 5V Hardware Manual

•controller User's Manuals and Data Sheets

•this QuickStart Instruction with general “Rapid Development Kit”

description, software installation hints and four example programs

enabling quick out-of-the box start-up of the phyCORE-ADuC812

in conjunction with the Keil software development tools

1.2 Overview of this QuickStart Instruction

This QuickStart Instruction gives a general “Rapid Development Kit”

description, as well as software installation hints and four example

programs enabling quick out-of-the box start-up of the

phyCORE-ADuC812 in conjunction with the Keil software

development tools. It is structured as follows:

1) The “Getting Started” section uses three example programs:

•"Hello" and "Blinky" to demonstrate the download of user code

to the Flash device using PHYTEC FlashTools98 for Windows.

2) The "Getting More Involved" section provides step-by-step

instructions on how to modify both examples, create and build

new projects and generate and download output files to the

phyCORE-ADuC812 using the Keil tool chain and

FlashTools98.

3) The "Debugging” section provides a fourth example

program - “Debug” - to demonstrate monitoring of the board and

simple debug functions using the µVision2 debug environment.

In addition to dedicated data for this Rapid Development Kit, this

CD-ROM contains supplemental information on embedded

microcontroller design and development.

Introduction

1.3 System Requirements

Use of this “Rapid Development Kit” requires:

•the phyCORE-ADuC812 SBC module

•the phyCORE Development Board LD 5V with the included DB-9

serial cable and AC adapter supplying 5 VDC / min. 500 mA

•the PHYTEC Spectrum CD

•an IBM-compatible host-PC (486 or higher running at least

Windows95/98)

1.4 The PHYTEC phyCORE-ADuC812

The phyCORE-ADuC represents an affordable, yet highly functional

Single Board Computer (SBC) solution in subminiature dimensions

(60 x 55 mm). The standard board is populated with a Analog Device

ADuC812 controller. The ADuC812 features an 8-channel 12-bit

resolution A/D-converter, two 12-bit D/A-converters, integrated

reference voltage source and a temperature sensor.

All applicable data/address lines and applicable signals extend from

the underlying logic devices to standard-width (2.54 mm / 0.10 in.)

pin headers lining the circuit board edges. This enables the

phyCORE-ADuC812 to be plugged like a “big chip” into target

hardware.

The standard memory configuration of the phyCORE-ADuC812

features 128 kByte external SRAM and 128 kByte external Flash for

code storage (64 kByte for FlashTools firmware and 64 kByte for

storage of user code). The Flash device allows direct on-board

programming. Three Chip Select signals are available for external

I/O connectivity.

The module communicates by means of an RS-232 transceiver and

operates within a standard industrial range of 0 to +70 degrees C. It

requires only a 150 mA power source.

PHYTEC FlashTools98 enables easy on-board download of user

programs.
