Hello!

I'm looking for any USB compliant 8-channel logic analyser schematics.Do anyone have an idea?

I started to think about building an interface using a Microchip PIC18F2455 Controller but I would appreciate to get some assistance...

Thanks!

Greg

If you want to build one for the experiance that is a great. One of the members here did one using an AVR but it was RS232.

If you are doing it to save money forget it. For $150 you can buy one that is very nice. The software on the PC is very good and it does UART, I2C SPI and Dallas 1 wire post processing. SparkFun Electronics - USB Logic Analyzer Saleae Logic. The Logic Analyzer, Remastered. Now shipping for$149

Currently it only runs on windows but they are activly working on ports to linux and mac.

This is one of the nicest tools I have.

Yeah, the Saleae logic analyzer is amazing. I tried out their demo interface software and it RAWKZ. Don't own one though...kind of what a USB-CAN bus or an o-scope first. IT's cheap enough so I'll just buy it when I have an immediate use for it.

Thank you 3v0,

Actually I am doing it for the experience. My goal is to do it as simple as possible but using USB.
