People have been using a Pi Pico as a logic analyzer in a pinch, and now [pico-coder] has shared a sigrok driver that adds proper support for a Pico to beloved tools like Pulseview.

A simple logic-analyzer design is compatible with all versions of Windows and pushes the PIC 18C252 chip to its speed limit to achieve a 1-MHz sampling rate (Figure 1). The circuit can examine three ...

With this software and a Keysight logic analyzer, digital designers can monitor DDR3/4 or LPDDR2/3/4 systems to identify elusive violations in protocol or bus-level timing.

Software really is the test instrument. Lecroy's BitTracer, which runs on the PETracer Gen2 Summit PCI Express Protocol Analyzer, provides a physical-layer view of PCI Express ...
