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 98 or later. Pro-

grams 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:

X Exceptionally fast support for floating-point arithmetic and transcendental functions.

X RS-232 and RS-485 serial communication.

X Analog and digital I/O drivers.

X I

C, SPI, GPS, file system.

X LCD display and keypad drivers.

• Powerful language extensions for cooperative or preemptive multitasking

• Loader utility program to load binary images into Rabbit targets in the absence of

Dynamic C.

• Provision for customers to create their own source code libraries and augment on-line

help by creating “function description” block comments using a special format for

library functions.

• Standard debugging features:

X Breakpoints—Set breakpoints that can disable interrupts.

X Single-stepping—Step into or over functions at a source or machine code level, µC/OS-II aware.

X Code disassembly—The disassembly window displays addresses, opcodes, mnemonics, and

machine cycle times. Switch between debugging at machine-code level and source-code level by

simply opening or closing the disassembly window.

X Watch expressions—Watch expressions are compiled when defined, so complex expressions

including function calls may be placed into watch expressions. Watch expressions can be updated

with or without stopping program execution.

X Register window—All processor registers and flags are displayed. The contents of general registers

may be modified in the window by the user.

X Stack window—shows the contents of the top of the stack.

X Hex memory dump—displays the contents of memory at any address.

X STDIO window—printf outputs to this window and keyboard input on the host PC can be

detected for debugging purposes.

printf output may also be sent to a serial port or file.
