NoICE 9.4

NoICE is a lightweight, Windows-based source-level debugger and in‑circuit monitor for classic 8‑ and 16‑bit microcontrollers. It pairs a tiny monitor on the target with a host-side UI to let you set breakpoints, single‑step through code, inspect and modify registers and memory, view disassembly or mixed source/disassembly, and download programs over simple links such as serial or BDM. Supporting a range of families (for example, 8051, 68HC11/12, 6809, AVR, and others) and integrating with common assemblers and C toolchains, NoICE is well suited for board bring‑up, education, and maintaining legacy embedded systems. Its focus on low overhead and clear target visibility makes it a dependable choice for lab benches and field diagnostics.
