Simple USB 8 channels logic analyzer

This analyzer uses a PIC 16F876 (or 16F873) and is based on the very fine "Cheap Logic Analyzer" project made by Ted Rossin.

I made two main changes to Ted's design:

• A USB connector instead of serial connector.
• An input buffer to protect the PIC from external signals

The PIC firmware and Windows software are downloadable from Ted's pages.

These pdf documents are available:

• Schema in pdf format
• Layout in pdf format
• Printed board in pdf format
