Logic Analyzer Software
Logic analyzer client software controls the Logic Sniffer hardware and displays the pretty logic graph.
We recommend this SUMP client.
Multi-platform Java client. A version of the SUMP client actively developed by Jawi in the forum.

- You'll need Java
- Support and bug reports
- Releases and requests
- Logic Sniffer 102 documents some features of the client
- Reset issues with Arduino
Other SUMP-compatible clients
The original software for the SUMP core used in the Logic Sniffer is a multi-platform Java application.
There are several other clients that support the SUMP protocol. They are in various stages of development.
- Overview of several SUMP-compatible clients
- Raphihouri’s Windows/.Net client
- LogicAnalyzer (Java/RCP)
- Yet another client (Python) (Forum thread)
- Sigrok (no release yet)

- Compiled firmware: CC-BY-SA-NC*
- The compiled firmware uses a USB PID licensed from Microchip for our use. It is limited to 10K units, and licensed only for our OLS hardware production, therefore we have to limit use of firmware compiled with these numbers to non-commercial use. You are free to compile the firmware from source without the PID and use it under the terms of the GPL.
