EFERENCE

To develop and debug programs for the Jackrabbit (and for all

other Z-World and Rabbit Semiconductor hardware), you must

install and use Dynamic C. This chapter takes you through the

installation of Dynamic C, and then provides a tour of its major

features with respect to the Jackrabbit.

4.1  An Overview of Dynamic C

Dynamic C integrates the following development functions into one program:

•

Editing

•

Compiling

•

Linking

•

Loading

•

In-Circuit Debugging

In fact, compiling, linking and loading are one function. Dynamic C does not use an In-

Circuit Emulator; programs being developed are downloaded to and executed from the 

“target” system via an enhanced serial-port connection. Program development and debug-

ging take place seamlessly across this connection, greatly speeding system development.

Other features of Dynamic C include:

•

Dynamic C has an easy-to-use built-in text editor. Programs can be executed and 

debugged interactively at the source-code or machine-code level. Pull-down menus and 

keyboard shortcuts for most commands make Dynamic C easy to use.

•

Dynamic C also supports assembly language programming. It is not necessary to leave 

C or the development system to write assembly language code. C and assembly lan-

guage may be mixed together.

•

Debugging under Dynamic C includes the ability to use 

printf

 commands, watch 

expressions, breakpoints and other advanced debugging features. Watch expressions 

can be used to compute C expressions involving the target’s program variables or 

functions. Watch expressions can be evaluated while stopped at a breakpoint, single-

stepping, or while the target is running its program.
