Upgrading Dynamic C
Dynamic C patches that focus on bug fixes are available from time to time.
Check the Web site
• www.rabbit.com/support/downloads/
for the latest patches, workarounds, and bug fixes.
You may need to download upgraded libraries to run an OP7100 purchased
after June, 2006.
When downloading the libraries from the Web site, click on the product-
specific links until you reach the links for the OP7100 download you
require. You will be able to either run the download directly from the Web
site, or you may choose to save it to run later.
New LCD Controller Chip
OP7100 units sold after June, 2006, have a new LCD controller chip because
the previously used LCD controller chip is no longer available. The new LCD
controller is not 100% code-compatible with the old chip, and therefore
changes were made to the LCD drivers. The updated drivers for the OP7100
are backward-compatible for use with the old LCD controller chip.
If you are using a program developed for the now-obsolete LCD controller
chip, you will need to replace either the existing Dynamic C OP71L.LIB,
OP71P.LIB, and OP71HW.LIB libraries or the LQVGA.LIB and PQVGA.LIB
libraries in your Dynamic C installation — you only have to replace one of
these two sets of libraries, depending on which set you used when you
created your original application. You may, of course, replace all five libraries,
which will allow you to access the other updated set at a later date.
Unzip the contents of the compressed file you opened or downloaded into
a non-Dynamic C folder to see the updated library files. If you customized
any of these libraries, you should first make backup copies of the libraries
you customized. Then customize the new libraries, if needed. Now copy
and paste the new libraries to replace the old versions in the LIB folder in
your Dynamic C installation. You will have to recompile your program
once you have replaced the libraries.
The changes to the libraries will improve the OP7100 screen update time
for OP7100 units using the new LCD controller chip. Otherwise, the form,
fit, and function of the OP7100 are not affected by the changes.
For applications that are operating in the landscape mode using the new
OP71L.LIB library, there is a macro that can be defined to enhance the LCD
performance for older OP7100s using the original LCD controller chip.
Add the following macro at the start of your program before the graphic
libraries are #used. Using the macro may increase your interrupt latency.
#define LCD_ENHANCED_MODE
