Logic Analyzer LAP-16128U

Der ZEROPLUS PC-Based Logic Analyzer LAP-16128U ist ein 16-Kanal USB-Logic-Analyzer mit bis zu 200MHz Samplerate und 128kSamples pro Kanal. Er wurde uns von Michael Kazda zur Verfügung gestellt.

Software

Mit einem Einzeiler-Patch kann man sigrok dazu bringen, ihn zu erkennen. Eine Anleitung zum Kompilieren von sigrok findet man hier.

• Der Patch wurde gemered und sofern man sigrok aus dem git repo baut, sollte es nun out of the box funktionieren.
