begin to flash.

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 message:

UUM Serial LCD 115200 Baud V1.0

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 programmed.

Locate the test program you loaded in Step 2 and program the chip. The test messages will display in the compiler debug window, and the backlight on the LCD will

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.

Step 15:

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.

Step 16:

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 month. NV
