A mouse or the keyboard’s Tab key is used to navigate
various items on the main window (Figure 1). The EV kit
software features three tabs: Configuration, Events and
Status, and BitMap Controls. Most of the main window’s
available functions and a few more can be evaluated
by using the pulldown menu. The left status bar at the
bottom of the main window provides the USB interface
circuit status. The center status bar provides the current
EV kit and macro engine status.
Upon starting the program, the EV kit software starts in
the Auto Read state. The software automatically detects
the Slave Address and begins reading the contents
of each register from the IC, updating each tab sheet.
The software starts up with the Events and Status tab
selected.
The Events and Status tab sheet (Figure 1) provides
the EV kit’s system and port events/status information
obtained from the IC registers. The System Events and
Status group box provides system-level information on
the VEE power supply, present operating mode, and
address in hexadecimal and decimal formats. The Port
Events group box provides the PSE port event or change
status. The Port Status group box provides the PSE port
