NoICE

Window Based - Symbolic Remote Debugger

NoICE is a Window based Symbolic Remote Debugger for use with a variety of microcoprocessor target. It is intended to replace the HEX-Monitor programs oftec used for such debugging, but is much more powerful. The debugger consist of a Target-Specific Window program, NOICExxx.EXE, and a Target-Resident monitor program. The two programs comunicate via RS 232, at use selectable baud rate from 300 to 57600. Processors currently supported are the Z80, Z180, Z8, 8051, 80(1)96, 6809, 68HC11, 68HC12, 68HCS12, 68HC08, MSP430, 68HC05, 6502.

The PC-hosted approach has a number of advantages over a simple Hex Monitor. The Target-Resident monitor is simple and small: less than 1024 bytes for most version. The simplicity of the monitor eases the process of porting to new hardware platform.

The PC has a more flexible display than the generic terminals used by most Hex Monitors. NoICE mantains a number of windows containing register, source, and other data.

Because the size of code on PC does not penalize the target, a wide variety of features may be added.

Features include:

• Source Level Debug (currently, assembly language files only).
• A Disassembler.
• A file viewer for files of any size, in ASCII or HEX.
• Memory display and editing, including loading of Intel HEX and Motorola S1 records files.
• A virtually unlimited number of breakpoints.
• Hardware-free single step using automatically inserted breakpoints.
• Definition of symbols, which may be used in expressions and by the disassembler.
• The ability to record and play back files of commands.
• ON-Line Help.

NoICE may be operated via pul-down menus, using either mouse or keyboard, or via command line. Keyboard commands are generally similar to those of traditional Hex Monitors. Command keywords are case insensitive.
