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.
Astro 5 + Starlight 0.37 site at site/ with teal/steel theme.
Content sourced from 14 reverse engineering docs, master reference,
and custom firmware source. Includes Tabs, Badge, Steps, Aside,
FileTree, and CardGrid components throughout. DiSEqC SVGs with
click-to-zoom via starlight-image-zoom. All internal links validated.
Pagefind search indexes all 32 pages.
Custom firmware (SDCC + fx2lib) implements all stock vendor commands
(0x80-0x94) plus new commands for spectrum sweep (0xB0), raw BCM4500
register access (0xB1/0xB2), and blind scan (0xB3). Compiles to 6.3KB
of code with healthy RAM margins.
RAM loader (fw_load.py) uses the FX2 0xA0 vendor request to load
firmware into RAM without touching EEPROM -- power cycle restores
factory firmware. Supports Intel HEX and raw binary formats.
Includes original BDA driver source (headers, C++ implementation, INF
installer files), DiSEqC implementation PDF with extracted markdown
and SVG vector graphics.
