Help Menu
The 'Help' menu can be used to view the Datasheet
or this app note while prototyping with the Windows
GUI. During software installation, the datasheet
and app note are loaded in the same directory as
the program to automatically find them using this
feature. The 'About' selection will show the GUI
version number. Refer to Summit's web site for the
most current datasheet and GUI software
(www.summitmicro.com).

Configuration
Pull Down Menu
This menu has an option that will check for
communications between the device and the PC. This
selection should be tried first before changing any
options. If the test passes, then all other options
can be left in the default condition.

Setup
Options
In the 'File' pull-down menu under "Options", there
are "Settings" to set the I2C clock frequency and
delays before I2C Read and Write operations. The
default settings work with most PCs, so these
settings are only for circumstances where the PC
cannot communicate successfully with the SMX3200
programming 'Dongle'. The "Auto-Read
Configuration/Memory After Write" check box enables
a checksum test which compares the GUI hex settings
or file to the programmed device at the end of a
Write sequence. It does this by performing a Write
immediately following a Read.

Interfacing
Options
In the 'File' pull-down menu under "Options", there
are "Advanced" settings for parallel Port
Interfacing. The window in Figure 7 sets different
options for programming the device using the PC
parallel port. The 'Parallel Port Interfacing'
should always be set to 'Dongle'. The 'Parallel
Port Driver' and address is indicated here and can
be changed if a problem is encountered.
