Web Serial HMI + USB CDC Firmware (Octolux ↔ RP-series)
Public Unreviewedby Caleb
Build a paired NTX HMI (Chromium kiosk on Octolux) + firmware (USB CDC on RP2040/RP2350) that auto-connects over USB with no permission picker. End-to-end recipe: Pico SDK firmware template, HMI Web Serial via getPorts() + VID filter, Chromium SerialAllowAllPortsForUrls policy, udev MODE=0666 for /dev/ttyACM*, SCP + chromium-restart + screencast-bounce deploy, CDP verification, visible-debug-strip diagnostics, and a 12-row failure-mode table.

Health: the size chip is green when right-sized, yellow when getting long, red when the model likely skims it. A green check is a passed preamble/structure signal; an amber mark is a gentle nudge, not a hard failure.
