5.1.1 Using Dynamic C
You have a choice of doing your software development in the flash memory or in the
SRAM included on the RCM2000. The flash memory and SRAM options are selected
with the
The advantage of working in RAM is to save wear on the flash memory, which is limited
to about 100,000 write cycles. The disadvantage is that the code and data might not both
fit in RAM.
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 95, 98, 2000,
NT, Me, and XP. Programs can be downloaded at baud rates of up to 460,800 bps after the
program compiles.
Dynamic C has a number of standard features.
• Full-feature source and/or assembly-level debugger, no in-circuit emulator required.
• Royalty-free TCP/IP stack with source code and most common protocols.
• Hundreds of functions in source-code libraries and sample programs:
• Powerful language extensions for cooperative or preemptive multitasking.
• Loader utility program to load binary images into Rabbit targets in the absence of
• Provision for customers to create their own source code libraries and augment on-line
