Hi, I've just bought the UTD2102C digital oscilloscope ( http://www.uni-trend.com/UT2102C.html ), but unfortunately the accompanying software doesn't work with 64-bit Windows 7, neither with Linux. I've connected it to my wife's 32-bit machine and recorded the USB transmitted data, when working with 32-bit Windows. Generally the protocol seems to be relatively simple (I could distinguish the control commands transmitted via control transfers and measured data transmitted vie bulk transfers), so it should be possible to write an application working with UTD2102C based on libusb. Anyway it would be much easier having the description of the protocol. Maybe this protocol is similar to better documented protocols used by scopes of other brands? I've asked the manufacturer about availability of the protocol description, but I do not expect too much (form my previous experience in similar problems). I'd appreciate any pointers and suggestions. --=20 Best regards, WZab --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
