User Defined BIOS File
Use this option to change from the default BIOS to a user-specified file. Enter or
select the file using the browse button/text box underneath this option. The check box
labeled
use must be selected or else the default file BIOS defined in the system regis-
try will be used. Note that a single BIOS file can be made for compiling both to RAM
and Flash by using the preprocessor macros _FLASH_ or _RAM_. These two macros
are defined by the compiler based on the currently selected radio button in the
BIOS
Memory Setting
group box.
User Defined Lib Directory File (same as the command line compiler option “-lf”)
The Library Lookup information retrieved with
<Ctrl+H> is parsed from the libraries
found in the “lib.dir” file, which is part of the Dynamic C installation. Checking the
Use box for User Defined Libraries File, allows the parsing of a user-defined replace-
ment for the “lib.dir” file. Library files must be listed in the “lib.dir” file (or its
replacement) to be available to a program.
If the function description headers are formatted correctly (See “Function Description
Headers” on page 52.), the functions in the libraries listed in the user-defined replace-
ment for the “lib.dir” file will be available with <Ctrl+H> just like the user-callable
functions that come with Dynamic C.
Watch Code
Allow any expressions in watch expressions
This option causes any compilation of a user program to pull in all the utility func-
tions used for expression evaluation.
Restricting watch expressions (May save root code space)
Choosing this option means only utility code already used in the application program
will be compiled.
