<d1b2> <JScho> Can someone tell me what the specs are when using the Glascow as a serial protocol analyzer with Sigrok? I see that there is no RAM memory on the interface so I assume the max speed is limited by the USB connection?
<d1b2> <dragonmux> it's good for up to 50MHz or the max of the USB connection (480Mb/s) - whichever you hit first. There is limited buffering capabilities in-FPGA as there is block RAM used as an interface FIFO.
<d1b2> <dragonmux> there is also an addon that gives it Hyper RAM for more memory-intensive applications which might be useful for your needs too
<d1b2> <JScho> Does it work well with Sigrok?

<d1b2> <dragonmux> we've never tried it directly from in Sigrok to be fair, so we don't have an answer to that.. but we'd suspect it would
<whitequark> it doesn't currently
<d1b2> <dragonmux> ah, well.. good to know

<d1b2> <dragonmux> uh, not that we know of.. but that's really a @esden question
<d1b2> <dragonmux> (he's currently asleep/AFK, but that should mean he sees this when he gets back to the keys)

<d1b2> <Attie> @tpw_rules - I don't believe they're for sale, but you can put them together yourself - https://github.com/esden/glasgow-addons/tree/master/hardware/ram-pak
