Not yet, the GUI is not yet fully functional, I'm working on fixing that. Expect improvements soonish. > am i right, or is there another way to get the data in ? You can load a file (any file really), it will be interpreted as binary 8-channel logic analyzer output (each byte denotes 8 signal values). But as mentioned above, the UI is not too useful yet, zoom and scroll don't yet work properly either (partially yes, but it needs fixing). > --- /dev/null > +++ b/libsigrok/hardware/dummy/dummy.c > @@ -0,0 +1,355 @@ > +/* > + * This file is part of the sigrok project. > + * > + * Copyright (C) 2010 Bert Vermeulen <[email protected]> That should be Copyright (C) 2010 Pieter Heremans <[email protected]> rather, I think, as you wrote the code. > +#define NUM_PROBES 32 > +#define TRIGGER_TYPES "01" Such a demo driver would be useful indeed. I haven't been thinking much about how to properly implement it, but maybe some kind of Python script integration would be useful (similar to the Python protocol decoder scripts we'll have). That would allow us to write small Python scripts to generate any kind of sample data on-the-fly (I2C, SPI, whatever) with certain characteristics and timings etc. The "dummy" (or "demo") driver should then be able to provide any configurable number of channels, configurable samplerates, etc. so that the Python scripts can generate the various demo sample streams. That's for later though, for now I think a simple C code implementation of an I2C or SPI stream or similar in the dummy.c file should be fine. We'll generalize that later, when the Python integration is more usable (that's being heavily worked on right now, there's no real stable API or anything yet).
