Step 1. Download sigrok PulseView (https://sigrok.org/wiki/Downloads) and install it. At the moment (February 2023, the nightly Binaries are down, releases are fine but old)
Step 2. Plug the logic analyzer into a USB port.
Step 3. Run the Zadig driver installer https://zadig.akeo.ie/
Step 4. Run PulseView. Connect a Dupont cable to the signal (CH0, for example) and ground pins on the logic analyzer to a source (TTL max 5V level only, no analog voltages!).
