Figure 2 - Help Menu

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).

Figure 3 - Configuration Window

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.

Figure 4 - Options Window

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 Read immediately following a Write.

Figure 5 - Options Window		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.
