No, you're just a bit unlucky to hit 2 issues at the moment: - OLS and other such devices are currently not detected on Windows, this has been the case for a while now (nobody has looked into it yet). It's Windows-specific, since the devices work OK on other OSes. See also: http://sigrok.org/wiki/Windows#Limitations_and_TODOs http://sigrok.org/bugzilla/show_bug.cgi?id=562 - I've just tested a Logic Pirate (I have one as well), and it is detected on Linux, so you're quite surely hitting the Windows bug I mentioned above. However, the current code also doesn't handle the Logic Pirate yet since it doesn't report sufficiently much metadata apparently (which is the case for a few other Dangerous Prototype devices as well, unfortunately). I'm afraid we'll have to create some sort of profiles in the driver to correctly handle all the different devices and use only the capabilities they actually have. I'm assuming jawi's OLS client does something similar. Example run on Linux: $ sigrok-cli -d ols:conn=/dev/ttyACM0 --scan -l 5 [...] sr: ols: Got metadata key 0x01 value 'Logic Pirate (40 MHz)'. sr: ols: Got metadata key 0x02 value '2013-06-25'. sr: ols: Got metadata key 0x00, metadata ends. sr: ols: Disabling demux mode. sr: serial: Closing serial port /dev/ttyACM0. sr: hwdriver: Scan of 'ols' found 1 devices. The following devices were found: ols - Logic Pirate (40 MHz) FPGA version 2013-06-25 $ sigrok-cli -d ols:conn=/dev/ttyACM0 --samples 10 sr: session: ols using connection (null) has no enabled channels! Failed to start session. (the reason being that the Logic Pirate doesn't send metadata for the number of channels, and so on) Uwe. -- http://hermann-uwe.de | http://randomprojects.org | http://sigrok.org ------------------------------------------------------------------------------ Dive into the World of Parallel Programming The Go Parallel Website, sponsored by Intel and developed in partnership with Slashdot Media, is your hub for all things parallel software development, from weekly thought leadership blogs to news, videos, case studies, tutorials and more.
