2.4 Installing Dynamic C

If you have not yet installed Dynamic C version 7.30 (or a later version), do so now by

inserting the Dynamic C CD from the OP7200 Tool Kit 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 online documentation is installed along with Dynamic C, and an icon for the docu-

mentation menu is placed on the workstation’s desktop. Double-click this icon to reach the

menu. If the icon is missing, create a new desktop icon that points to default.htm in the

docs folder, found in the Dynamic C installation folder.

The latest versions of all documents are always available for free, unregistered download

from our web sites as well.

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.

2.5 Starting Dynamic C

Once the OP7200 is connected to your PC and to a power source, start Dynamic C by

double-clicking the Dynamic C icon on your desktop or in your Start menu. Dynamic C

uses the serial port specified during installation

If you are using a USB port to connect your PC to the OP7200, choose Options > Project

Options

and check “Use USB to Serial Converter” in “Serial Options” on the Communi-

cations

tab. Click OK to save the settings.

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

OP7200 and go through a sequence

of steps to cold-boot the OP7200 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 OP7200 by selecting Reset Target/Compile BIOS on the Compile menu or

by pressing <Ctrl-Y>. Try the different COM ports in the OPTIONS menu until you find

the one you are connected 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.

If you receive the “BIOS successfully compiled …” message after pressing <Ctrl-Y> or

starting Dynamic C, and this message is followed by a communications error message, it

is possible that your PC cannot handle the 115,200 bps baud rate. Try changing the baud

rate to 57,600 bps as follows.

• Locate the Serial Options dialog in the Dynamic C Options > Communications

menu. Change the baud rate to 57,600 bps.
