2.3 Installing Dynamic C
If you have not yet installed Dynamic C version 7.26P (or a later version), do so now by
inserting the Dynamic C CD in your PC’s CD-ROM drive. The CD will auto-install unless
you have disabled auto-install on your PC.
If the CD does not auto-install, click Start > Run from the Windows Start button and
browse for the Dynamic C setup.exe file on your CD drive. Click OK to begin the
installation once you have selected the setup.exe file.
The Dynamic C User’s Manual provides detailed instructions for the installation of
Dynamic C and any future upgrades.
NOTE: If you have an earlier version of Dynamic C already installed, the default instal-
lation of the later version will be in a different folder, and a separate icon will appear on
your desktop.
2.4 Starting Dynamic C
Once the LP3500 is connected to your PC and to a power source, start Dynamic C by dou-
ble-clicking on the Dynamic C icon on your desktop or in your Start menu.
If you are using a USB port to connect your computer to the LP3500, choose Options >
Project Options
and select “Use USB to Serial Converter” on the Communications tab.
Click OK.
Dynamic C assumes, by default, that you are using serial port COM1 on your PC when
you are running a program. If you are using COM1, then Dynamic C should detect the
LP3500 and go through a sequence of steps to cold-boot the LP3500 and to compile the
BIOS. If the error message “Rabbit Processor Not Detected” appears, you have probably
connected to a different PC serial port such as COM2, COM3, or COM4. You can change
the serial port used by Dynamic C with the OPTIONS menu, then try to get Dynamic C to
recognize the LP3500 by selecting Reset Target/Compile BIOS on the Compile menu.
Try the different COM ports in the OPTIONS menu until you find the one you are con-
nected to. If you still can’t get Dynamic C to recognize the target on any port, then the
hookup may be wrong or the COM port might not working on your PC.
Dynamic C automatically uses a maximum debug baud rate of 38,400 bps when an
LP3500 series board is in use.
