PiPiLogicAnalyzer 7.1.0

Project

• The project is now called PiPiLogicAnalyzer. The Python package is pipilogicanalyzer, the
  command pipilogicanalyzer, the settings live in a directory of that name (the settings of the
  previous name are taken over on the first start) and the environment variables are
  PIPILOGICANALYZER_SETTINGS_DIR and PIPILOGICANALYZER_DECODERS; the previous names still work.
• The firmware is called PiPiLogicAnalyzer as well: the sources are in firmware/PiPiLogicAnalyzer,
  the images are named PiPiLogicAnalyzer_<BOARD>[_Turbo].uf2 and a board identifies itself as
  PIPI_LOGIC_ANALYZER_<BOARD>_V<major>_<minor>. The application also accepts the previous
  identification, so boards with an older firmware keep working. USB VID/PID (0x1209/0x3020) and
  the hardware of Agustín Giménez Bernad are unchanged.

Application

• The device list and the multi device dialog only offer detected analyzers; other serial ports
  are no longer listed.
• Clicking the name of an annotation row (or double-clicking an annotation) opens the row as a
  list in a window of its own: filter, copy (e.g. a disassembly listing), and selecting an entry
  shows it in the waveform.
• Multi device sets are no longer triggered by the master only: the board of the trigger channel
  evaluates a pattern or an edge (firmware of this project) and starts the other boards, or every
  board waits for an edge on its external trigger input.
• Pattern triggers use every group of consecutive trigger inputs the firmware reports (Pico:
  channels 1–21 and 22–24 instead of 1–16), fast matching included.
• C64 bus decoder: the Bus cycles row keeps the value read or written visible when zoomed out
  (R $FFFC=$E2, FFFC=E2, E2) instead of showing only the address.
• Device → Install or update firmware: every image shows the firmware version it contains, in
  the list and in its description.
• Channels can be made lower (or taller) to fit more of them on the screen: Alt + mouse wheel,
  View → Taller/Shorter channels (Ctrl+Shift+Up/Down) or the Channel height slider; the
  height is remembered.
• Help → Online documentation opens the wiki of this project; the wiki of the original software
  by gusmanb, which documents the hardware, has an entry of its own.

Project

• SECURITY.md (private vulnerability reporting, where problems are plausible) and a Contributor
  Covenant CODE_OF_CONDUCT.md.
• Corrected license statements: a few bundled sigrok decoders are MIT or BSD, not GPL, and the
  AppImage runtime is distributed with the Linux build. The copies of the Raspberry Pi
  lwipopts.h and pico_sdk_import.cmake carry their BSD-3-Clause notice again.
• Source files carry a copyright and SPDX-License-Identifier header; pyproject.toml declares
  GPL-3.0-or-later.
• Pull requests that only change documentation now run the tests as well, so a required check can
  pass.

Firmware

• Identifies itself as V7_1. A multi device set only accepts boards with the same version, so
  flash every board of a set with this firmware.
• Trigger type 5: edge trigger that also drives the trigger output.
• Pattern triggers accept all channels on consecutive GPIOs; the capabilities report
  EDGE_TRIGGER_OUT and PATTERN_GROUPS.
