Getting up and running with PulseView and reading pin output with an Analyzer! Introduction Logic Analyzers are inexpensive devices that allow you to just take a look at what a small number of pins on a chip are up to. They can be hooked into software like PulseView to read pin output and decode it into something more useful. Many decoders are available, but in this introduction we’ll have a quick look at PulseView and reading (decoding) UART data. I’ve previously written about UART and how to find them with a JTAGulator, but here’s a different approach.
