DCC-EX Native Throttle v0.1.0
Standalone Linux x86_64 executable of the DCC-EX native-protocol throttle. No installation needed.
Asset updated 2026-09-02: F3 is now a toggle — one command per press, alternating on/off. Decoders that sound on every function edge (short whistle) tooted twice per click with press/release momentary handling; F3 now makes exactly one edge, one toot per click. Also: direction is a single colour-coded toggle (green FORWARD / orange REVERSE) instead of radio buttons.

Features
- Run tab: throttle slider (0-126), direction toggle, STOP / E-STOP ALL, function buttons F1-F8 (momentary; F3 toggles once per press for edge-triggered whistle sounds)
- Programming tab: service-mode address and CV read/write, CV29 bit editor, CV name lookup, program-on-main writes
- Track power control per district (MAIN/PROG) with live current draw and overload latch
- Console with raw command entry
Notes
- Built on Arch Linux; it needs a comparably recent glibc. For older distros, rebuild from source:
python3 -m venv .venv && .venv/bin/pip install pyserial pyinstaller && .venv/bin/pyinstaller --onefile --windowed --name dccex-throttle dccex_throttle.py - Closing the window sends
<0>(track power off) by design. - Tested against a real EX-CSB1: throttle, direction, and function handling (including the F3 single-toot behaviour) confirmed on the rails.
