It should also be noted that variations in the excitation current do
not affect the measurement system, as the input voltage from
the RTD and reference voltage across R1 vary ratiometrically with
the excitation current. Resistor R1 must, however, have a low
temperature coefficient to avoid errors in the reference volt-
age over temperature.
QUICKSTART DEVELOPMENT SYSTEM
The QuickStart Development System is a full featured, low cost
development tool suite supporting the ADuC816. The system
consists of the following PC-based (Windows-compatible) hard-
ware and software development tools.
Hardware:
ADuC816 Evaluation Board, Plug-In
Power Supply and Serial Port Cable
Code Development:
8051 Assembler C Compiler
(2 Kcode Limited)
Code Functionality:
ADSIM, Windows MicroConverter
Code Simulator
In-Circuit Code Download: Serial Downloader
In-Circuit Debugger:
Serial Port Debugger
Misc. Other:
CD-ROM Documentation and Two
Additional Prototype Devices
Figures 53 shows the typical components of a QuickStart Devel-
opment System while Figure 54 shows a typical debug session.
A brief description of some of the software tools’ components in
the QuickStart Development System is given below.

Download—In-Circuit Serial Downloader
The Serial Downloader is a software program that allows the user
to serially download an assembled program (Intel Hex format file)
to the on-chip program FLASH memory via the serial COM1
port on a standard PC. An Application Note (uC004) detailing
this serial download protocol is available from www.analog.com/
microconverter.
DeBug—In-Circuit Debugger
The Debugger is a Windows application that allows the user to
debug code execution on silicon using the MicroConverter UART
serial port. The debugger provides access to all on-chip periph-
erals during a typical debug session as well as single-step and
break-point code execution control.
ADSIM—Windows Simulator
The Simulator is a Windows application that fully simulates all
the MicroConverter functionality including ADC and DAC
peripherals. The simulator provides an easy-to-use, intuitive, inter-
face to the MicroConverter functionality and integrates many
standard debug features; including multiple breakpoints, single
stepping; and code execution trace capability. This tool can be
used both as a tutorial guide to the part as well as an efficient way
to prove code functionality before moving to a hardware platform.
The QuickStart development tool-suite software is freely
available at the Analog Devices MicroConverter Website
www.analog.com/microconverter.
