Changelog

All notable changes to this fork of the OpenGD77 firmware (MD-UV380 / DM-1701).

This project is still in pre-release iteration, so changes are collected as a single running list until the first versioned release.

Unreleased

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).

Misc

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