MAX5432 Evaluation Kit

Keyboard Navigation

Press the TAB key to select each GUI control. The

selected control is indicated by a dotted outline. Using

SHIFT+TAB moves the selection to the previously

selected control. Buttons respond to the keyboard’s

SPACE bar. Some controls respond to the keyboard

UP and DOWN arrow keys. Activate the program ’s

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

of the desired menu item. Most menu items have one

letter underlined, indicating their shortcut key.

Simple I 2 C Commands

There are two methods for communicating with the

MAX5432 EV kit, through the normal user-interface panel

(Figure 1) or by using low-level SMBus? commands avail-

of this tool. Figure 3 shows a simple SMBus write-byte

operation using the included 2-wire interface diagnos-

tics tool. In this example, the software is writing data

0xF8 to the register address 0x11 (write to volatile mem-

ory) to the device with the device address 0x50. The

data sequence sets the MAX5432 wiper position to 32.

Refer to Application Note 476, at www.maxim-ic.com,

for information and comparison of the SMBus and

I 2 C protocols.

General Troubleshooting

Problem: Software reports it cannot find the inter-

face circuit.

? Is the interface circuit power LED lit?

able through the 2-Wire Interface utility from the main pro-

gram’s Options | Interface (Advance Users) main menu.

A window is displayed (Figure 3) that allows I 2 C opera-

tions, such as SMBusReadByte and SMBusWriteByte .

Do not use the SMBusReadByte operation because

the MAX5432 does not send data to the master.

?

?

Is the USB cable connected?

Has Windows plug-and-play detected the board?

Bring up Control Panel -> System -> Device

Manager and look at what device nodes are indi-

cated for USB. If there is an “unknown device ”

node attached to the USB, delete it—this forces

Note: The I 2 C dialog boxes accept numeric data in

binary, decimal, or hexadecimal. Hexadecimal numbers

must be prefixed by $ or 0x. Binary numbers must be

exactly eight binary digits. See Figure 3 for an example

plug-and-play to try again.

? Are jumpers JU1–JU4 properly configured for USB

operation?
