    FreeTRX v0.1.0 Pre-release

    DK1DA released this 2026-07-06 16:34:10 +00:00 | 47 commits to main since this release

    0.1.0

    First versioned release of FreeTRX (fork of OpenGD77 R20260131).

    Features

    • Screen dimming — optional idle dimming of the backlight to a fraction of
      the configured brightness (Off / 100% / 50% / 30%), in Auto backlight mode.
      Any activity (keys, rotary, RX, TX) restores full brightness. New setting in
      Display Options.
    • Mute — one-tap audio mute:
      • SK2 short-tap toggles mute on the VFO/Channel screens (except while a DMR
        QSO is on screen, where SK2 keeps its "set TX TG to incoming" function).
      • Turning the volume knob fully down is also treated as muted.
      • While muted: a bold "M" appears in the status bar (left of the battery)
        and the red LED flashes (0.5 s every 2 s).

    Display / UI

    • S-meter redrawn as discrete blocks — 9 green blocks (S1–S9) plus 6 red
      blocks (S9+10…+60), with gaps and a proportionally-filled leading block, and a
      scale label row beneath (S1 S3 S5 S7 S9 / +20 +40 +60).
    • 7-segment "LED" frequency font for the VFO and SK1-held frequency display,
      with faintly-lit inactive segments; digits are wider than the normal font.
    • Main-menu icons — a small glyph next to each top-level menu entry.
    • Layout spacing adjusted so the contact/TG line, the DMR talkgroup/talker and
      the private-call caller ID clear the new S-meter label row.

    Fixes

    • DMR no longer hard-faults. The AMBE codec is now called through C function
      pointers instead of the old inline assembler (which modern GCC miscompiled),
      fixing the freeze-on-DMR that required a battery pull.
    • Fixed the DMR talkgroup/talker and private-call caller ID overlapping the
      S-meter labels.

    Build / Tooling

    • Dockerized build using the Arm GNU Toolchain 14 (matching the official
      builds); always a clean build. ./flash.sh helper for flashing with model,
      language and DMR donor.
    • Integrated the OpenGD77 screen grabber (gd-77_screen_grabber.py) and the
      GD-77 loader into the repo.
    • TOOLS.md documents building, flashing, screenshots and language files.

    Project

    • Renamed the project to FreeTRX (fork of OpenGD77). New README.md
      documenting the fork and its upstream source; original OpenGD77 README kept as
      README.OpenGD77.md. Added LICENSE.md reproducing the inherited OpenGD77
      license (modified BSD 3-Clause + non-commercial clause; not GPL-compatible).
    • On-screen branding renamed to FreeTRX (splash screen + Firmware Info name).
    • README notes this iteration is developed/tested only on the TYT MD-UV380 and
      Retevis RT-3S      , with a contact for testing on other supported radios.
    • Firmware-info credits simplified to "Marcus DK1DA" and a reference to
      "The original OpenGD77 authors".

    Misc

    • Added Marcus DK1DA to the firmware-info credits ("Modified Fork by").
