Figure 16 shows the main screen of the control software in its
initial reset state (all outputs off). Using the mouse, any input
can be connected with one or more outputs by simply clicking
on the appropriate radio buttons in the 16 × 8 on-screen array.
Each time a button is clicked on, the software automatically
sends and latches the required 40-bit data stream to the evaluation
board. An output can be turned off by clicking the appropriate
button in the Off column. To turn off all outputs, click on RESET.
The software offers volatile and nonvolatile storage of configura-
tions. For volatile storage, up to two configurations can be stored
and recalled using the Memory 1 and Memory 2 Buffers. These
function in an identical fashion to the memory on a pocket
calculator. For nonvolatile storage of a configuration, the Save
Setup and Load Setup functions can be used. This stores the
configuration as a data file on disk.
Overshoot on PC Printer Ports’ Data Lines
The data lines on some printer ports have excessive overshoot.
Overshoot on the pin that is used as the serial clock (Pin 6 on
the D-Sub-25 connector) can cause communication problems.
This overshoot can be eliminated by connecting a capacitor
from the CLK line on the evaluation board to ground. A pad
has been provided on the solder-side of the evaluation board to
allow this capacitor to be soldered into place. Depending upon
the overshoot from the printer port, this capacitor may need to
be as large as 0.01 µF.
