Save Settings

The MAX6639 EV kit software allows the user to save

desired GUI settings by selecting File | Save Settings

from the menu bar. GUI setting files can be saved only

as .INI files.

Load Settings

To restore a saved GUI setting, select File | Load

Settings from the menu bar. Next, select the .INI file

with the desired GUI settings and observe as the GUI

reconfigures appropriately.

Advanced User Interface

There are two methods for communicating with the

MAX6639, through the normal user-interface main win-

dow or through the SMBus/I2C commands available by

selecting Options | Interface (Advanced Users) from

the menu bar. An Advanced User Interface window

pops up with the 2-wire interface tab selected, which

allows the SMBus/I2C-compatible protocols, such as

read byte and write byte, to be executed. The only

SMBus/I2C-compatible protocols used by the MAX6639

are:

1 - SMBusWriteByte(addr,cmd,data8)

4 - SMBusReadByte(addr,cmd) -> data8

The combo and edit boxes accept numeric data in

hexadecimal and should be prefixed by 0x. See Figure

7 for an example of this tool.

In this example, the software is reading from Device

Address 0101111 r/w (binary), and register address

0x00.
