Logic Analyzer Software
Logic analyzer client software controls the Logic Sniffer hardware and displays the pretty logic graph.
We recommend the multi-platform Java client actively developed by Jawi in the forum.

- Support and bug reports
- Releases and requests
- Logic Sniffer 102 documents some features of the client
- Reset issues with Arduino
There are several other clients that support the SUMP protocol and work with the Logic Sniffer. They are in various stages of development.
This is a simple all-in-one solution that will guide you through the update process.
- PIC firmware v3.0
- FPGA bitstream v3.07
The Logic Sniffer is a mature project, there are no known bugs in the firmware or bitstream.
For many, many alternate update utilities and tutorials, please see Various update applications for the Open Logic Sniffer.
In rare cases keyboards may stop working under Windows 7 after an update. This appears to be a Windows 7 problem. Here's a solution.

- Firmware source: GPL (excluding Microchip USB stack)
- 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.
