It's been a fair while since I looked at the sigrok code, but last I saw, it has drivers for different logic analyser hardware platforms. Some communicate with a basic serial (RS232-equivalent) interface and protocol, some might use USB. There is no one standard "sigrok protocol", as far as I know. See, if you haven't already, http://sigrok.org/wiki/Supported_hardware for the list of supported hardware platforms. If you're building your own USB device, I guess you could "clone" one of the existing platforms' interface, and make it "magically" work with sigrok. Not sure if that could mean license/IP issues, of course, be at least slightly careful would be my recommendation. I'm not a lawyer. /Emil ------------------------------------------------------------------------------ Benefiting from Server Virtualization: Beyond Initial Workload Consolidation -- Increasing the use of server virtualization is a top priority.Virtualization can reduce costs, simplify management, and improve application availability and disaster protection.
