[Unreleased]

Planned

• Firmware deglitching / debounce on the BPD trigger path to reject false edges from interferogram noise.

[1.1.0] - 2026-07-23

Added

• SYS:TIMESTAMP:DELTAENC OFF|UINT8|UINT16 (aliases 0|1|2|8|16 in FW) — UART timestamp delta encoding; set may reply OK - WARNING: …; query returns limit warning. Python SetTimestampsEncoding / GetTimestampsEncoding.
• LASER:SWE:STATUS? — 1 while laser sweeping (sw low), 0 idle; allowed during sweep. Python GetSweepStatus.
• LASER:SWE:COUNT? / LASER:SWE:COUNT 0|RESET — cumulative laser sweep counter; Python GetSweepCount / ResetSweepCount.
• Optional COM=None with discover() / connect() — autodetect PSoC trigger via *IDN?.
• pySSTri.commands command table and pySSTri.utilities helpers; arg-aware auto-methods (e.g. SetFreqDivision(n)).
• SIG:TRIG:TIMESTAMP? — pull last sweep timestamps (TSU n ov fc t0 enc + payload); Python GetTimestamps().
• SYS:TRIG:NOT TIMESTAMP / 5 — unsolicited timestamp frame each sweep; Python SetModeTimestamp() / waitTimestamps().
• Firmware Polarity Low 1.3.1: ISR Timer capture timestamps (µs), up to 4000 samples/sweep, first→last frequency, active-low LEVEL sweep gate.

Changed

• Default git branch is main (was release); scripts/release.py defaults to main.
• TSU wire format: always TSU <n> <ov> <fc> <t0> <enc> (enc last); host decodes from the header only.
• End-of-sweep notify restored (OFF|TIME|COUNT|FREQ|ALL|TIMESTAMP); frequency from first→last timestamp span.
• Docs: false-trigger / interferogram-noise note; deglitching called out as future firmware work.

Fixed

• Timestamp path uses Timer capture ISR (DMA capture path abandoned).

[1.0.0] - 2026-07-22

Added

• Pip-installable package layout (pyproject.toml, git-tag release via scripts/release.py).
• Package pySSTri exporting SSTriggerInterferometer / notifymode from serialInterface.py.
• Optional notebooks extra (matplotlib, jupyter, ipykernel) for trigger_example.ipynb.
• SCPI-style UART protocol v1.0 (CRLF): *IDN?, SIG:TRIG:DIV, SIG:TRIG:EVENTS:COUNT?, SIG:TRIG:EVENTS:FREQ?, LASER:SWE:TIME?, SYS:TRIG:NOT.
• Firmware identity string with FW_VERSION and FW_DATE via *IDN?.
• Error replies ERROR: 0 (unsupported/invalid) and ERROR: 1 (laser sweeping).
• Sets acknowledge with OK; host uses write+read for all commands.

Changed

• Repo layout: firmware under psoc5/firmware/ (formerly Trigger/); Eagle assets under pcb/.
• Class renamed from PSOC5_trigger to SSTriggerInterferometer.
• Clean break from legacy commands (freq_int, SetMode_* wire strings, bare-number divider, leading \r).
• Default frequency division on reset is 2.
• End-of-sweep host sync uses single SYS:TRIG:NOT OFF|TIME|COUNT|FREQ|ALL (replaces separate wait/mode).
