Thanks Lucas! What is the use case compared to existing [hid] externals?

+1 thank you, a really cool project!

My comparison AFAICT (from working on [hid] a little [1]):

[hidraw]

• is more cross-platform, including Windows
• has a way more modern code base and build system
• offers less "semantic" output -- in the sense that [hidraw] gives you

event codes that you process in your patch yourself, whereas [hid] decodes many of the possible button presses and other events

• uses an external library, libusb/hidabi, for its functions -- [hid]

only uses OS functions and headers iirc

Maybe we should prepare a wiki page or other documentation item at some point listing the different possibilities of working with USB HID devices in Pd.

Best, Albert.

Hi all,

The hidraw external reads raw bytes from hids.

You can find it on Deken for most OSs.

You have to build yourself for very old rasperry-pi's or new M1 or M2 macs.

@Albert thanks for the explanation.

You might be interested in looking at the sources of

https://deken.puredata.info/results.html?name=hidio

the .dek file is just a .zip.

It looks that Martin have done all the update to [hid]. I had only checked on Windows and not building myself but the object works and it's supposed to compile on Linux and Mac.
