This firmware has no published screen capture. Some diagnostics primarily report through USB serial. Screen appearance remains unverified here; see its app README for the intended behavior.
What to expect
Debug-oriented serial diagnostic; an actual breakpoint session remains UNKNOWN. Use its application guide for controls, prerequisites and recorded device checks.
Capabilities used
Install and inspect
This environment is built in CI but is excluded from the browser installer. Use the PlatformIO workflow below.
pio run -e hello-debug
pio device list
pio run -e hello-debug -t upload --upload-port <port>
pio device monitor --port <port> -b 115200Replace <port> with the discovered device. Build before upload. Read the app's partition and storage notes before switching firmware.

Implementation, a passing build, observed serial operation and physical interaction are separate evidence levels. Check the guide's open device checks before relying on an unmeasured behavior.
