TL;DR
Claude Code successfully reverse-engineered the firmware for the 121GW multimeter, transforming it into C code in less than 24 hours. This achievement showcases the power of modern tools and techniques in software engineering, particularly in the realm of firmware analysis. The entire process is documented in the EEVblog episode, where Claude walks through the steps taken, including using the ST-LINK V2 programmer and installing GCC and Ghidra, a software reverse-engineering tool.
