MAX1036 Evaluation Kit

General Description

Features

ꢀ Proven PC Board Layout

The MAX1036 evaluation kit (EV kit) is designed to evalu-

ate the MAX1036. The MAX1036 is an 8-bit four-channel

(two-differential-channel) ADC with a 2-wire serial inter-

face. The MAX1036 EV kit board supports three standard

2-wire serial interface speeds: standard mode (S-Mode),

fast mode (F-Mode), and high-speed mode (HS-Mode);

however, the software provided with this EV kit only sup-

ports standard mode.

ꢀ Windows 95/98 Evaluation Software

ꢀ 2-Wire Serial Interface

ꢀ Fully Assembled and Tested

The provided Windows 95/98^®software uses the paral-

lel (printer) port of an IBM-compatible PC to emulate a

processor with a 2-wire serial interface (S-Mode). The

Windows software also provides a friendly graphical

user interface (GUI) to exercise the features of the

MAX1036 with control buttons and pulldown menus.

Quick Start

Recommended Equipment

Before you begin% the following equipment is needed:

Detailed Description of

Software

The evaluation software’s main window (Figure 1) con-

trols the setup byte and config byte. It also displays

the voltage and output code of the input signal(s)%

depending on the configuration of the MAꢂ1036.

•

MAꢂ1036EꢁKIT

A 5ꢁ DC power supply

An IBM-compatible PC with Windows 95/98

Read ADC

The Read ADC button manually reads the MAꢂ1036

while using the current setup and configuration byte set-

tings. When the AutoRead checkbox is checked% the

software automatically reads the MAꢂ1036 approximately

every 300ms. AutoRead allows users to modify the setup

and configuration bytes on-the-fly without having to man-

ually press the Read ADC button each time.

An available parallel port (DB25 female connector

on back of PC)

•

A standard 25-pin% straight-through% male-to-female

cable to connect the computer’s parallel port to the

MAꢂ1036 Eꢁ kit board

Procedure

1) Connect a cable from the computer’s parallel port

to the MAꢂ1036 Eꢁ kit board. Use a 25-pin straight-

through% female-to-male cable.

Setup Byte

The Setup Byte always begins with a start-bit value of

1. The SEL2% SEL1% and SEL0 bits control the state of

the reference. The CLK bit selects either internal clock

or external clock mode. The UNI/BIP bit selects either

unipolar or bipolar mode. Setting RST to zero resets the

configuration register. The setup register remains

unchanged. The X Don’t Care bit can be ignored.

7efer to the MAꢂ1036 data sheet for more informa-

tion on the SEL2% SEL1% and SEL0 bits within the

Setup Byte.

2) Install the MAꢂ1036 Eꢁ kit software on your com-

puter by running the INSTALL.EꢂE program on the

floppy disk. The program files are copied and

icons are created in the Programs section within

the Start menu.

3) Connect a 5ꢁ DC power supply between the pads

labeled +5 and OND on the MAꢂ1036 Eꢁ kit board.

4) Apply an analog input voltage (0 to ꢁ

to the

7EF)

pad labeled AIN0 (with respect to the pad labeled

OND) of the MAꢂ1036 Eꢁ kit board.

Configuration Byte

The Config Byte always begins with a start-bit value of

zero. The SCAN1 and SCAN0 bits select the scanning

mode. The CS1 and CS0 bits select one of the four

analog input channels. The CS2 and CS3 bits are

ignored. The SE/DIFF bit selects either single-ended or

differential mode. 7efer to the MAꢂ1036 data sheet for

more information on the SCAN1% SCAN0% CS3% CS2%

CS1% and CS0 bits within the Config Byte.

5) Start the MAꢂ1036 Eꢁ kit program by double click-

ing its icon located in the Programs section within

the Start menu.

6) The program automatically detects the MAꢂ1036

Eꢁ kit board and displays 2-Wire Hardware

Detected in a green font. The AIN0 label (main win-

dow) should automatically display the voltage

applied to the pad labeled AIN0 on the MAꢂ1036

Eꢁ kit board.

Reference Voltage

The evaluation software assumes a 4.096ꢁ reference

voltage% unless otherwise specified. To override the

internal 4.096ꢁ reference value% ensure bit SEL2 equals

_______________________________________________________________________________________

MAX1036 Evaluation Kit

zero and bit SEL1 equals 1 within the Setup Byte.

Then% apply the new reference voltage at the ꢁ7EF pad

on the board% type in the new reference voltage% without

the volt unit% and press the Set Vref button. The Eꢁ kit

software uses the value typed in the ꢁref field to trans-

late the digital code to a voltage.

Detailed Description of

Hardware

The MAꢂ1036 is a four-channel (two-differential-channel)

8-bit ADC with a 2-wire serial interface. The open-col-

lector inverter (U2) interfaces the PC parallel port to the

2-wire serial interface. U2 and the associated circuitry

are only required when interfacing to the parallel port.

Power the MAꢂ1036 Eꢁ kit from a 5ꢁ DC power supply.

Keyboard Navigation

When you type on the keyboard% the system must know

which control should receive the keystrokes. Press the

TAB key to move the keyboard’s focus from one control

to the next. The focused control is indicated by a dotted

outline. SHIFT+TAB moves the focus to the previously

focused control. Buttons respond to the keyboard’s

SPACE bar. Some controls respond to the keyboard’s

UP and DOWN arrow keys. Activate the program’s

menu bar by pressing the F10 key% then press the letter

of the menu item you want. Most menu items have one

letter underlined% indicating their shortcut key.

User-Supplied 2-Wire Interface

The MAꢂ1036 Eꢁ kit provides a proven PC board layout

and software to evaluate the features of the MAꢂ1036.

The Windows software only supports a 2-wire serial inter-

face in S-Mode. To evaluate the MAꢂ1036 with a user-

supplied 2-wire serial interface in F-Mode or HS-Mode%

do the following:

1) Disconnect the MAꢂ1036 Eꢁ kit from the PC parallel

port.

2) Install 3k resistors at locations 75 and 7X. (This

resistor value may require optimization for each

system.)

3) Connect the 2-wire bus to the SDA% SCL% and OND

pads.

4) 7efer to the MAꢂ 1036 data sheet to ensure all tim-

ing specifications are met.
