PXView

PXView is a Qt-based signal analysis software for PXLogic logic analyzers and a wide range of third-party instruments. It is built upon the sigrok project and DSView, providing a comprehensive GUI for signal capture, protocol decoding, and automated testing.

• Multi-mode signal acquisition — Logic analyzer, oscilloscope (DSO), and mixed-signal oscilloscope (MSO) modes with simultaneous digital and analog channel display
• 220+ protocol decoders — I²C, SPI, UART, CAN, PWM, USB, JTAG, I²S, Modbus, IR (NEC/RC5/RC6/SIRC), 1-Wire, SD card, and many more, with both Python and high-performance C implementations
• 187+ hardware drivers — Native support for PXLogic devices plus broad compatibility with Saleae Logic, ChronoVu LA, ASIX Sigma, FTDI-based analyzers, Hantek DSO, Rigol DS, and many other instruments via libsigrok
• MCP (Model Context Protocol) server — Built-in HTTP API server (port 10110) enabling AI tools like Claude Code, Codex, and OpenCode to control devices, capture signals, and decode protocols through natural language
• Headless mode — Run PXView --headless for automated testing and CI/CD pipelines without a GUI, with full API access via MCP and WebSocket (port 10430)
• USB hotplug — Cross-platform hotplug support with automatic device detection and reconnection
• Glitch filter — Pulse analysis tool with histogram visualization, threshold adjustment, and undo support
• Data export — Export raw capture data and decoded results to CSV, binary, or session files (.pxc)
• Cross-platform — Linux (AppImage), macOS (Universal DMG for ARM64 + x86_64), and Windows

PXView provides native support for PXLogic USB logic analyzers:

PXView uses libsigrok as its hardware abstraction layer. All 89+ libsigrok hardware drivers are compiled in, and PXView scans every driver at startup via sr_driver_list() + sr_driver_scan(). However, the level of GUI support varies by device category.

These devices receive all PXView features: operation mode selection (Buffer/Stream), channel mode switching, device mode (Logic/Analog/DSO/MSO), hardware trigger configuration, DSO analog options (vdiv, coupling, offset, probe factor), firmware version checking, disk cache configuration, and stream buffer settings.

These devices are automatically discovered via USB bus scan and appear in the PXView device dropdown. They support basic capture operations: channel enable/disable, sample rate selection, sample limit configuration, and stream mode auto-detection. They do not support: operation mode switching, hardware trigger, DSO-specific analog options, channel mode configuration, or firmware management.

These drivers require a conn= parameter (serial port, TCP/VXI address, or Bluetooth MAC) to scan for devices. PXView's GUI does not provide a connection specification dialog, so these devices cannot be used from the PXView GUI. They are compiled into libsigrok and may be accessible via the MCP API or sigrok-cli with explicit connection parameters.

Total: 89+ hardware drivers compiled into libsigrok, with 33 accessible via the PXView GUI (2 full + 31 basic) and 56+ requiring serial/SCPI/Bluetooth connection parameters not exposed by the GUI.

See the detailed build and installation guides:

• INSTALL.md — English
• INSTALL_zh.md — 中文

Pre-built packages are available for download from the releases page.

PXView references the sigrok project's official upstream repositories via git submodules, ensuring complete open-source repository paths and git history are included in source distribution. Clone with --recursive:

git clone --recursive <PXView-repo-url> PXView
cd PXView

If already cloned without submodules, initialize them manually:

git submodule update --init --recursive

Included submodules (located at the repository root, alongside libsigrok/):

The sigrok-firmware-fx2lafw/ submodule contains source code but no pre-compiled .fw files. Build them on-site using the sdcc compiler:

# Install sdcc (example: Ubuntu)
sudo apt install sdcc

# From the repository root
bash build_fx2lafw.sh

This produces 15 fx2lafw-*.fw files under sigrok-firmware-fx2lafw/hw/*/. The ninja install step automatically detects and packages them into share/sigrok-firmware/.

If fx2lafw is not built, CMake will emit a WARNING and only the 8 ASIX Sigma + Sysclk LWLA firmware files will be packaged (FX2-based devices will not be recognized).

PXView includes a built-in MCP server that allows AI programming tools to control hardware devices through a standardized protocol. The server starts automatically on port 10110.

PXView is in a usable state with official releases. However, it is still a work in progress — some basic functionality is available and working, while other features remain on the TODO list.
