Dear all, we are trying to get a National Instruments DA/AD card (NI PCIe 6259, see link below) working with comedi/analogy.
The drivers seem to be doing something, I can pull up the analog outputs to 10V (max voltage) using the example program cmd_write. So I think the issues I am having are stemming from not understanding and using the API correctly rather than driver issues (but I might be wrong). Thus, I am trying to understand how to actually write a waveform to the analog output and am so far not very successful and the comedi doc seems a bit cryptic and scarce to me in this respect. - Does anyone have example code how this is done? - Is the correct procedure to issue first a command (comedi_snd_command) and then use the write command (comedi_sys_write) to achieve this? - Interestingly the write command (comedy_sys_write) is not the one responsible for pulling up the output, it seems to already happen in the comedi_snd_command. - My current approach was trying to modify the cmd_write example. Is this a good idea? Any help and pointers would be greatly appreciated! Thanks a lot and best regards Jonas PS: Card being used NI PCIe 6259: http://sine.ni.com/nips/cds/view/p/lang/en/nid/14128 _______________________________________________ Xenomai-help mailing list [email protected] https://mail.gna.org/listinfo/xenomai-help
