[Discuss-gnuradio] Gnuradio over Zynq

Taking a quick look at a branch of that hash tag, the Reset function simply sets d_nitems = 0. There are 4 helper functions within the Skip Head block of old that are not in the current one; namely setting the number of items to skip, checking how many items are to be skipped, checking how many

Thanks for this, your git-fu is much stronger than mine! I wonder why the mutator func for d_nitems didn't make it into the current version. At least for me, it's really useful to have. Anyway, looks like it won't be too bad to graft in. Thanks again. -Doug

Hi Julian, this really depends on how your serial data gets into your PC, but assuming you're on linux and have the data coming in over a properly configured character device (ie. something that appears as /dev/ttyS* or the like), you could just use the file source and open that device.

Agreed, but as soon as device setup is through with your device (thus the properly configured character device) and your reading program behaves nicely (which I'd expect GR's file_sink to do), just reading from a character device should work, if I'm not mistaken. However, this brings us to a new
