- Splash screen and Firmware Info name now show "FreeTRX". - Firmware-info credits: "Marcus DK1DA", a separator, and a thank-you to the original OpenGD77 authors. - README documents that this iteration is developed/tested only on the TYT MD-UV380 and Retevis RT-3S, with a contact for testing other supported radios. - CHANGELOG updated. Hardware/tooling identifiers (build filename, MD-UV380 model IDs, hotspot version string) intentionally left unchanged to avoid breaking flashing and Pi-Star/MMDVM compatibility.

# 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).
|
||
- 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").
