Here we continue the discussion about the GPIO 16 Open development project.
The initial discussion started HERE.
The link to the initial specifications, plus particular updates extracted during the discussion: http://wiki.redpitaya.com/index.php?title=GPIO16

Extension module and casing

Will it be possible to use the extension module together with some protective casing for Red Pitaya when it is available?
Some photos were shown already, it seems connectors are accessible, which is not the case with range setting jumpers.
How about ventilation?

Hi guys!
I would like to give my contribute to this interesting project, but' there is something that i don't understand.
Can someone clearly explain how the data get from the FPGA memory through AXI interface are exchanged with nginx?
Basically i don't understand for example how "rp_osc_signals[][]" after has been filled up from "rp_osc_set_signals()" is read from nginx.
I'm sorry if the question may sound trivial but it's taking time to me to face it.
Best regards, Flavio

The new project which was shown in the Blog - from Martin Ossmann - seems to have more potential than just what was shown.
Gain and phase meter is fine, Impedance also. Will it be available as an app? Any further info?

Hello All,

Has there been any progress on the GPIO 16 project? Is there any sample software that would interact with the proposed hardware?

Thanks and Happy New Year !
Bruce

What is the fastest practical switching speed of the GPIO? Are you using system level API calls and so are they somehow scheduled in and out (no pun) with the OS or is there a low-level driver?
