Using the Reach Technology Display
1. Locate the power-supply connector and
connect it to the bare leads of an AC
adapter as shown in Figure 2. Pay atten-
tion to the polarity of the power-supply
connections. Attach the power-supply
connector to the display and plug in the
AC adapter.
2. Use the serial cable interface to connect
the Reach Technologies display to an
available COM port on your PC. You
may have to use a DE9 extension cable
since the serial cable interface is short.
3. Start the BMPload.exe program on
the Reach Technology supplemental
CD. Select the serial COM port you are
using and a baud rate of 115200. Press
the Load BMP List button and select
the demo.lst file from the Samples\ColorTouchscreen\BMP_Macro folder on the Dynamic
C supplemental CD. Next, press the Add Macro File button and select the Macros.mac file from
the same folder on the Dynamic C supplemental CD. Finally press the Store into SLCD button to
move these files to the Reach Technology display—this may take a few minutes. Press the Quit button
to exit the BMPload.exe program when done.
4. Disconnect the serial cable interface from your PC COM port and use the serial adapter cable to connect
header J3 on the Prototyping Board to the serial cable interface as shown in Figure 2 to establish a serial
connection with the RCM3720. Reconnect the programming cable to the PC COM port if you had to dis-
connect it in order to use the PC COM port for the serial connection to the Reach Technology display in
the above steps.
5. Open the sample program LCD_PONG1.C, which is in the Dynamic C SAMPLES\ColorTouch-
screen folder. Press function key F9 to compile and run the program. The Reach display will show a
ball bouncing around in a rectangle, leaving a multi-colored trail behind it.
Where Do I Go From Here?
You are now ready to go on to other sample programs and to develop your own applications. Application
Note AN411, Color Touchscreen Application Kit, takes you through loading and using the sample pro-
grams included with the Dynamic C supplemental CD, and describes Z-World's software drivers.
RCM3700
User's Manual provides complete hardware reference information and describes the software
function calls for the RCM3720 and the Prototyping Board. The Reach Technology supplemental CD con-
tains additional information about the display and its specifications.
Troubleshooting
The files used with the Reach Technology display should be from the Dynamic C supplemental CD.
