BL4S100 User’s Manual 33
4. SOFTWARE
Dynamic C is an integrated development system for writing
embedded software. It runs on an IBM-compatible PC and is
designed for use with single-board computers and other devices
based on the Rabbit microprocessor.
Chapter 4 provides the libraries, function calls, and sample pro-
grams related to the BL4S100.
4.1 Running Dynamic C
Since the BL4S100 has a serial flash memory, all software development must be done in
the static SRAM. The flash memory and SRAM options are selected with the Options >
Program Options > Compiler
menu. Select Store Program in Flash on the “Compiler”
tab for the program to run normally.
For debugging purposes, you may select Store Program in RAM on the “Compiler” tab
so that download speed is as fast as possible. Note that programs stored in RAM will be
lost when the BL4S100 is reset, so this option should be used only for debugging.
Developing software with Dynamic C is simple. Users can write, compile, and test C and
assembly code without leaving the Dynamic C development environment. Debugging
occurs while the application runs on the target. Alternatively, users can compile a program
to an image file for later loading. Dynamic C runs on PCs under Windows NT and later—

be downloaded at baud rates of up to 460,800 bps after the program compiles.
