demo.py: hotplug mock used [0x08, 0x50, 0x51, 0x61], corrected to
[0x08, 0x10, 0x51] per hardware bus scan. 0x50 was never on the bus;
0x61 was speculative.
device.py: known device map had 0x60 "BCM3440 tuner" and 0x61
"ISL6421 LNB controller" — neither appears on the SkyWalker-1 I2C bus.
Replaced with 0x10 "Tuner / LNB controller" per confirmed scan.
Phase D firmware hardening: vendor commands 0xBD (streaming diagnostics)
and 0xBE (I2C hot-plug detection) with Python library, bridge, and demo
support. All I2C operations use timeout-protected helpers, BCM4500 reads
are rate-limited during streaming, and frame counter reads use atomic
read-verify-reread pattern. Counters saturate instead of wrapping.
Generate motor.svg and survey.svg for the new TUI screens. Fix
MotorScreen bug: two Horizontal widgets shared id="motor-usals-inputs",
causing MountError. Replaced with classes="usals-input-row" since both
rows need the same styling. Regenerated all 13 screenshots.
Update tui.mdx with Device, Stream, and Config screen sections
including keyboard shortcuts, Tabs/Steps components, and safety
warnings. Update generate_screenshots.py to capture all 11 screens.
Regenerate all SVGs with current sidebar layout.
- New docs page (tools/tui.mdx) covering all 5 RF modes, keyboard
shortcuts, easter eggs, and splash screen with inline SVG screenshots
- Screenshot generation script using Textual headless Pilot API to
capture 8 screens in demo mode without hardware
- Fix dark mode toggle: migrate from removed App.dark to App.theme API
(Textual 7.x breaking change)
- Update social link to Gitea repo, add TUI to sidebar
New features:
- P1 green phosphor radar scope widget on Track screen with LUT-optimized rendering
- Splash screen with pre-baked ANSI half-block art from 16colo.rs/Mistigris
- Star Wars ASCII animation via telnet (ctrl+w) with IPv6 happy eyeballs and offline fallback
- Dark Side / New Hope toast notifications on theme toggle
- Kitty terminal detection with cat emoji on splash
Robustness (from Apollo code review):
- Circuit breaker in track loop after 10 consecutive errors
- Input validation for frequency, symbol rate, step size across scan/spectrum/track
- Consolidated sys.path manipulation into __init__.py
- Radar scope pre-computes dist/angle LUT per pixel on resize
Cleanup:
- Removed unused imports across lband, monitor, scan, signal_gauge
- Moved Pillow/textual-image to optional dev deps (splash uses pre-baked ANSI)
- Added 41-test pytest suite covering telnet IAC parsing, radar geometry, splash assets
Textual's ContentSwitcher expects regular Widget/Container children,
not Screen subclasses. Screen's on_mount fires for all children at
once regardless of visibility, so demo workers for all 5 modes
started simultaneously and competed for the bridge.
Container children get proper on_show/on_hide from ContentSwitcher's
visibility toggling — only the active panel's worker runs.
Separate entry point (skywalker-tui) that reuses skywalker_lib.py
unchanged. Five RF modes: spectrum, scan, monitor, lband, track —
each with threaded USB bridge workers for non-blocking I/O.
Includes --demo mode with synthetic signal generation (Gaussian
peaks, noise floor, AGC simulation) for development without hardware.
Custom widgets: spectrum bar chart, rolling waterfall, signal gauge,
sparkline history, transponder table, device status bar.
