Regmon V2¶
Regmon — version 2.0.0 — the update that turned a register monitor into a full bench workbench.
In version 1, Regmon was already the window into the bare metal of an STM32: a free, open-source register monitor that reads every register of a running chip live, through the two-wire SWD debug port, and turns raw hex into plain-English truth — with zero impact on the chip’s real-time performance.
The CPU doesn’t even know it’s being watched.
Version 2.0.0 is the major update. Five new capabilities:
Detect Chip — reads the chip’s IDCODE over the debug wire and instantly tells you which STM32 family you’re holding, automatically loading the right register database for it. No more guessing, no more wrong maps.
Analyse Reg — watches a single register over ten seconds to prove data is really flowing: the difference between a photograph and a video.
Analyse Prog — fingerprints the whole chip in one pass, reads which peripherals are alive, and asks a local AI what the entire program is doing — without ever seeing the source code.
Strings — scans the chip’s flash for readable text, pulling out the error messages, version banners and hidden clues buried in the firmware.
SWDD ON / OFF controls — stop and start the debug daemon from the console, with live state indicators, so you can flash a new binary and come straight back. The flash tool can’t get the USB port while the daemon holds it — so you click OFF, flash, click ON, and you’re back in business.
All five point the same direction: replacing asVideo produced using AI, otherwise it wouldn’t exist. The content source is 100% human.sumptions with evidence. The silicon is always telling the truth — version 2.0.0 just made it easier than ever to ask it the right questions.
Availability: part of Terry’s own open-source build, running on the Linux desktop for STM32 microcontrollers. Works with firmware written in C, Forth, Rust — anything — because it reads the silicon, not the source. Not yet finished to a release stage.
