All of the UUM software is included with the Dios compiler. Locate the
“UUMSerLCD.txt” program. It is in
the projects\UUM directory where
you installed the compiler. Now,
program this file into the Dios.
You should see the following
UUM Serial LCD
UUM switches. Set them to the following:
Power = On (up)
Program = 1 (up)
UART= None (middle)
This sets up the serial graphic LCD module to be
Locate the test program you loaded in Step 2 and
program the chip. The test messages will display in the

You may have to adjust the contrast trimmer if the
information is not displayed. At this point, you can set the
UART switch to Ser LCD mode (up). This will allow you to
send commands to the serial graphic LCD from the PC.
The complete list of commands can be downloaded from
the Kronos Robotics website.
Set the switches to the following:
Power = On (up)
Program = 2 (down)
UART= Chip to chip (down)
This sets up the utility module to be programmed.
Now locate the “UUM.txt” program in the projects\UUM
directory and program the utility module. You should see
the display change to the main UUM display.
Install the bottom panel with four 3/8-inch machine
screws. You now have a complete and working UUM.

In Part 2, I will present you with a complete operations manual and show you a few examples of how to
operate the UUM. At this point, you should have enough
information to start playing with the UUM. Check out
the serial graphic LCD instructions and use the debug
terminal to display text
and graphics on the LCD
from your PC.
As a teaser, take a look
at Figure 20. Using a Vishay
IR Sensor or IR photo transistor on one of the analyzer
ports, we can read the pulses of just about any IR
remote pulse train. In this
case, it’s the output of a
Skyfi2 XM Radio IR remote
and key. We will dig into
many more examples next
