id5100 — CI-V control for the ICOM ID-5100

Software control layer for the ID-5100 mobile transceiver over CI-V, via the RT Systems USB-29A cable (FTDI) plugged into the radio's [SP2] jack.

Verified link: /dev/ttyUSB0, 9600 baud, radio CI-V address 0x8C.
No dependencies — pure stdlib (termios), no pyserial.

Layers

File	Role	Tested by
`civ.py`	Pure CI-V codec: BCD freq/level encode-decode, frame build/parse	`test_civ.py` (11 unit tests)
`radio.py`	Serial transport + high-level `Radio` class (get/set freq, mode, vol, sql, smeter)	live-radio integration
`cli.py`	Command-line front end	live-radio integration
`server.py`	Web control-panel server (stdlib `http.server` + JSON API)	live-radio integration
`panel.html`	Instrument-panel web UI (amber VFD, S-meter, mode/level controls)	headless screenshot
`civ_probe.py`	One-shot link probe (read VFO frequency)	—

CLI

./cli.py status            # freq, mode, volume, squelch, s-meter at a glance
./cli.py freq              # read VFO (MHz)
./cli.py freq 146.52       # set VFO to 146.520 MHz
./cli.py mode fm           # set mode: lsb/usb/am/cw/fm/dv
./cli.py vol 30            # set AF volume 0-255 (read with no arg)
./cli.py sql 60            # set squelch level 0-255
./cli.py smeter            # read S-meter 0-255
# global: --port /dev/ttyUSB0  --baud 9600

Web panel

python3 server.py            # http://<host>:8550/  (binds 0.0.0.0 -> phone-reachable)
# --port 8550  --serial /dev/ttyUSB0  --baud 9600

Holds the serial port for its lifetime, so don't run cli.py while the server is up (one process owns /dev/ttyUSB0). The page polls /api/status ~1/s for live frequency, mode, S-meter, squelch, and levels; controls POST to /api/{freq,mode,vol,sql}.

Library

from radio import Radio
with Radio("/dev/ttyUSB0", 9600) as r:
    r.get_frequency()        # -> Hz
    r.set_frequency(146_520_000)
    r.get_mode()             # -> ("FM", 0x05)
    r.set_volume(30)

Tests

python3 -m unittest test_civ -v

Gotchas / verified facts

[SP2] is the CI-V port on the ID-5100 (doubles as 2nd speaker jack).
Bus echo: the radio echoes your TX frame before replying; transact() filters frames where frm != RADIO_ADDR.
Frequency BCD is little-endian; level/meter BCD is big-endian (128 -> 01 28).
Mode FM = 0x05 confirmed empirically. DV = 0x17 is from the generic ICOM table and not yet verified on this radio — confirm before relying on it.
Scope is CI-V (operate the radio). D-STAR DR routing / callsign entry live in the separate RS-MS1A data-jack protocol, not here.
