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

Nothing yet.

0.11.0

• CRT-style shut-off animation — when powering off, the current screen collapses towards the middle (squeezed to a line, then a dot) like an old CRT switching off, replacing the "Power Off" message. (Colour displays only.)

0.10.1

• Fix: the muted "M" indicator in the status bar overlapped the GPS text when GPS was enabled. The header icon is removed; the muted state is shown by the flashing red LED alone.

0.10.0

• SMS recipient from contacts — when composing a message, press GREEN in the recipient field to pick the destination from your private-call DMR contacts (or type a DMR ID manually and press DOWN to move to the text).
• Contacts list shows everything — Menu → Contacts now lists all contact types together under the title "Contacts" instead of defaulting to the group filter; HASH still cycles the per-type filters (all / groups / private / all-call).

0.9.0

• Pride theme — the status/header bar and the menu title bar are now painted in the top rainbow-stripe colour so they blend into the background instead of showing as white boxes.

0.8.0

• Three new theme presets (Display Options → "Theme"): Red (black-on-red day / red-on-black night); Neon 80s, an 80s-synthwave palette that maps several neon colours (cyan, magenta, violet, green, yellow) across the individual UI elements over a dark background; and Pride, which paints the background as a rainbow pride flag with black text and white menu/header boxes kept readable over the stripes.
• Build: each build now prints a per-region memory-usage summary (FLASH / RAM / CCMRAM used, size and free) so the remaining headroom is visible after every build.

0.7.1

• Fix: the radio crashed when navigating the Messages menu with voice prompts enabled. Menu strings added after the voice-prompt pack was built map to a table-of-contents slot that doesn't exist; the player read past the end of the table. Such strings now play silence instead (also hardens the pre-existing strings sitting at the end of the table).

0.7.0

• DMR text messages (SMS) — full ETSI/Motorola-TMS-compatible messaging: compose on the keypad (multi-tap, up to 160 characters), inbox and sent box (8 messages each, persisted to flash across power cycles), 10 editable quick-text templates, an incoming-message popup with chime and one-key reply, and delivery confirmation (waits for the ETSI response PDU / ACK with a resend prompt on timeout). Transmits in the Motorola TMS format (UDP port 4007) understood by BrandMeister, hotspots and most OEM radios; receives both TMS and the Anytone/"DMR standard" format (port 5016) and answers delivery-report requests from other radios. Reachable from the main menu ("Messages") or a long-press on GREEN in channel/VFO mode. Options: "Wait for ACK" and "My ID only" (accept only messages addressed to your own DMR ID). Voice PTT is locked out while a message transmits, and hotspot mode is unaffected.
• Removed the main-menu icons — the top-level menu entries are plain text again.

0.6.0

• Theme presets — selectable on the radio in Display Options → "Theme": Custom (CPS-editable, default), BASIC 80s (Commodore 64 blue/light-blue), Terminal (green-on-black night / black-on-green day), and Vertexic (orange, black-on-orange day / orange-on-black night). The choice is stored in the codeplug custom-data area (migration-safe; defaults to Custom), and CPS theme edits only ever change Custom.
• Fix: green LED flickering between the red flashes while muted during a DMR QSO. The DMR RX handler re-asserts the green LED as soon as it reads it off, racing the main-loop mute clear; the green LED is now held off at the driver for the whole mute (and released on un-mute), so only the red flash shows.
• screenshot.sh — a one-command wrapper around the OpenGD77 screen grabber that auto-detects the serial port and sets up a self-contained Python venv (pyserial + pillow) on first run. Saves to screenshots/.

0.5.0

• Fix: un-muting during an active QSO left the LED off instead of returning to green. On un-mute the green RX LED is now restored from the current receive state (active DMR slot or FM/digital signal), so an in-progress call lights green again.
• MANUAL.md — a user-facing feature & usage guide covering both inherited OpenGD77 features and FreeTRX additions, each tagged 🟢 [FreeTRX] or ⚪ [OpenGD77]. Includes the spectrum scope (VFO sweep, hold #), channel add/delete, mute, dimming, and a button reference.
• Documentation website (website/) — MkDocs Material config that renders the markdown into a static, searchable HTML site (client-side search, dark/light theme). Built in Docker via ./website/build-docs.sh; the public URL is set with SITE_URL=…. For self-hosting on Forgejo.

0.4.0

• On-radio channel add/delete. The Channel quick menu (top button) has two new entries:
  • new channel — creates a blank 145.500 MHz FM channel in the first free slot, adds it to the current zone, and opens Channel Details to edit it. The zone is reloaded so the channel is immediately navigable.
  • Delete Channel — deletes the selected channel after a confirmation, and scrubs it out of every zone that referenced it. Refuses to delete the last remaining channel, and respects the read-only/APRS channel lock.
  • The new menu strings are translated (German, French, Italian, Spanish, Portuguese, Dutch, Danish, Swedish, Catalan, Finnish, Czech; English fallback for the rest).
• flash.sh now always rebuilds the language (.gla) packs, so edits to the language files are picked up instead of a stale pack being re-flashed.
• Release script now flags every release before v1.0.0 as a pre-release (and corrects the flag on re-runs).

0.3.0

• Fix a second voice-prompt crash on the Screen Dim menu row: the item label ("Screen Dim") is a raw literal, and the shared menu code voices labels via voicePromptsAppendLanguageString(), which crashes on any pointer outside the language table. That function now ignores non-language pointers, so a stray literal is skipped instead of hard-faulting. (The dim value is still announced.)

0.2.0

• Fix crash opening Display Options with voice announcements on: the Screen Dim value ("100%"/"50%"/…) is a plain literal, but the shared menu code fed it to voicePromptsAppendLanguageString(), which derives the prompt index from the string's offset within the language table — a foreign pointer produced a garbage index and crashed. The value now goes through voicePromptsAppendString(). Also moved the dim-level high bit off a low legacy option bit (bit 2 → 29) and clamped the level so it can never index past the option arrays.
• 7-segment frequency font: inactive segments are now off (background) instead of faintly lit — no dim "ghosting". "MHz" now matches the frequency colour, and there's 1px more space between the RX and TX frequency lines.
• Screen dimming: added a 15% idle-dim level (Off / 100 / 50 / 30 / 15).
• DM-1701 build support — the Docker build is now parameterized by platform; ./build-firmware.sh DM1701 produces OpenDM1701.bin (Baofeng DM-1701 / Retevis RT-84). Not officially tested yet.
• Release script (scripts/forgejo-release.sh) now builds and attaches a single platform or all of them, and reuses an existing release.
• README: added "What's different from OpenGD77" and a dedicated "Flashing" section.

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").
