PiLyzer 3.1.1 — Three-channel offline panel

PiLyzer 3.1.1 for macOS 13+, Universal (Apple Silicon and Intel).

CH1, CH2 and CH3 now appear before connecting an instrument, so the three-channel capability is visible immediately. Saved two-channel settings are preserved and extended with CH3. Once connected, the panel follows the instrument's actual capabilities, including older two-channel firmware.

The offline rate preview uses the Pico 2 firmware's 97-cycle ADC timing. Acquisition remains disabled until a device or Demo is connected.

Validation: 76 core tests passed; both Universal architectures built and the bundle signature verified. The running macOS app was checked while disconnected: all three channel controls and measurement columns are present.

Unzip the app and move it to Applications. The bundle is ad-hoc signed, not Apple-notarized; macOS may require System Settings → Privacy & Security → Open Anyway on first launch.

PiLyzer 3.1.0 — macOS Universal & WebUSB

PiLyzer for macOS is now available as a Universal app for Apple Silicon and Intel, macOS 13 or later.

Download PiLyzer-3.1.0-macOS-universal.zip, unzip it, and move PiLyzer.app to Applications. The bundle is ad-hoc signed, not Apple-notarized. If macOS blocks its first launch, approve it in System Settings → Privacy & Security → Open Anyway.

Included

• Three-channel Pico 2 oscilloscope, spectrum analyser, eight-channel logic analyser and voltage meter.
• Channel selection changes the acquisition rate; timing follows the device's capabilities. Firmware 1.5 uses a 97-cycle ADC minimum (approximately 495 / 247 / 165 kSa/s per channel).
• Trigger-only low-pass filtering, vertical positioning, per-channel ranges and probe scaling, CSV export and a built-in demo.
• Existing two-channel firmware remains supported; three-channel capture and GPIO20 test output require firmware 1.5.

Repository and browser app

• PiLyzer Web connects directly through WebUSB in desktop Chrome or Edge. Demo needs no hardware. Disconnect the native app before connecting from the browser.
• PiLyzer native sources, firmware and KiCad schematics now live in Pico2.
• The original PCBScope / DPScope SE macOS app is restored independently under PCBScope.

Validation

• PiLyzer: 74 native tests passed; both arm64 and x86_64 release builds and bundle signature verified.
• Restored PCBScope: 39 tests and app build passed.
• Web: 18 protocol/acquisition/signal tests passed; browser demo checks cover scope, FFT, logic, meter and capture controls.
• Firmware host regressions passed. The release does not flash connected hardware.
• Additional real-device checks passed with firmware 1.5: native 3-channel capture/trigger/logic; Chrome WebUSB 3-channel capture, meter and logic. The deployed Web app also includes a USB-session reset fix, with 19 tests passing.
