HID Keyboard functionality?

[SnakeNuts]

Hi all,

I've seen (and played around) with the HID mouse emulation in the pyb class, which is awesome!

However, I' was wondering if there is (or will be) any keyboard-emulation support? I've got some nifty ideas if that's possible.

Cheers,

Alex.

Have not tested any of the hid yet, but I got the urge as well for keyboard emulating.

I second that. It'd be great for those numerous keyboard emulation projects =)

Hi,

count me in, in fact you might want to read my rants about a DIY keyboard based on micropython

http://forum.micropython.org/viewtopic.php?f=5&t=284

I didn't find time to check into detail, but it shouldn't be to difficult to get something working taken that HID/mouse is there already

Is anyone working on this yet? I dont want to do duplicate work if possible. I'll strt and if I do get anywhere I'll post some code or work out how to submit to git.

Ive got plenty to learn before I get this right. This is way more difficult than I originally thought.

There have been a few requests now for extended HID functionality, so I'll start to look into it.

The idea would be that on boot up you specify "custom HID" and pass the HID descriptor, eg:

Code: Select all

descr = b"\x01\x02\x03..."
pyb.usb_mode('HID', descr)

Of course, the descr set of bytes will need to define a valid HID device, such as a keyboard or mouse.

I have made a pull request for custom HID functionality, including keyboard and mouse:

Is this part of the base image now? I just got a pyboard and my boot.py still shows the old format

import pyb
#pyb.main('main.py') # main script to run after this one
#pyb.usb_mode('CDC+MSC') # act as a serial and a storage device
#pyb.usb_mode('CDC+HID') # act as a serial device and a mouse

If not a standard part of the pyboard image, how would I go about adding it. I need a keyboard functionality for a project I'm working on.

Thanks

It's part of the main image but no boards have yet shipped with this image because it still requires some final testing.

You can download the latest version from https://micropython.org/download/, anything later than v1.3.10 from 13th Feb 2015, eg pybv10-2015-03-20-v1.3.10-227-g3425431.dfu will have it enabled. Links on that page tell you how to program the new image; also search on this forum for "dfu" if you get stuck.

The boot.py can remain the same to get the old USB+MSC behaviour. New behaviour is not well documented, but see https://github.com/micropython/micropython/pull/955.
