Infinity Keyboard doesn't work on OS X; works on Windows and Linux

[kevinmost]

Note: I am building this firmware on Ubuntu Linux because I can't seem to get the toolchain working properly on OS X.

Tested on a Macbook running 10.10 and a Macbook running 10.11. Neither device will detect the Infinity Keyboard when it's plugged in. Pressing the flash button on the bottom does put the device into bootloader mode, and then dfu-util can flash a firmware from OS X successfully.

Flashing the stock Kiibohd firmware that came with the Infinity makes the device work on all OSes, including OS X. Flashing tmk-keyboard results in a device that works on Linux and Windows, but not OS X.

On OS X, however, it seems like even when the keyboard is unresponsive, it will show up in lsusb.

lsusb output when the kiibohd firmware is installed:

Let me know if there's any more info I can provide and I will provide it ASAP. I'd really like to get this working on OS X

[tmk]

Thanks for the report.
Yeah, someone also reported exact problem on OSX. I guess there is something wrong related to USB3 or Mac OS X. This problem is specific to tmk/mbed protocol, the latest mbed version may fix this, I'll update mbed code some later.

Now flabbergast's tmk/chibios protocol is also available for Infinity60, it probably works on OSX. See this comment.

I tried the ChibiOS build and while it is detected on OS X, all my keys were transcribed over one to the left! Maybe something wrong with the matrix setup or something?

Also, the ChibiOS was detected on OS X but not Linux! :(

[tmk]

Ah, my Infinity60 is prototype and has different matrix than production model. My code is configured for it. comment out this line.
https://github.com/tmk/tmk_keyboard/blob/flabbergast-tmk_chibios/keyboard/infinity_chibios/config.h#L55

(Infinity is one of InputClub's brand?, they call their boards as Inifinty 60% and Infinity ergodox, confusing now :D )

[tmk]

Really sure?
I confirmed on Linux. It should work on Linux.

Also, the ChibiOS was detected on OS X but not Linux! :(

[kevinmost]

Commenting that line out makes it work on OS X now, thanks! 👍

But yeah, I did test it on Linux and it won't work. I built and flashed the firmware from Linux because, again, I can't get the build setup working right on OS X yet. But after building and flashing from this device, it's not responding as a keyboard... but is responding perfectly on my Mac!

I can actually build it on OS X when I use the ChibiOS variant! Very exciting. :)

My Linux box still won't let me type with the keyboard, unfortunately. It's Ubuntu 15.04. Maybe it's the 3.x kernel or something?

[tmk]

I'm also on 15.04 and I confirmed the problem.
To startup keyboard hid_listen console is needed for some reason. This problem is related to debug print, I'll look into further.

For a while workaround is disabling console function by commenting out this in Makefile.

#CONSOLE_ENABLE = yes   # Console for debug

[kevinmost]

Nice, that worked! Thanks so much for all the help. If anyone else stumbles upon this issue and is looking for a solution, the way to get your Infinity60 working on OS X and Linux (and you can even build on OS X!):

Check out the flabbergast-tmk_chibios branch.

cd tmk_core/tool/chibios

git clone -b kinetis https://github.com/flabbergast/ChibiOS.git chibios

Go back to the keyboard/infinity_chibios folder

Edit the config.h and comment out #define INFINITY_PROTOTYPE

Edit the Makefile and comment out CONSOLE_ENABLE = yes

Now make clean && make and you have a built .bin that can be flashed with dfu-util. :)

[kaansoral]

Thanks a lot for this info, I will use it to convert my infinities to tmk's when I can find some free time

flabbergast is such a life saver too :)

[kevinmost]

Also should point out, I had some issues with lag in the keyboard once I moved to the ChibiOS build; I thought maybe ChibiOS wasn't as responsive as mbed was or something? But it turns out that if you look in the config.h for the infinity_chibios folder, there's a line #define DEBOUNCE 5. I think that setting that to #define DEBOUNCE 0 has removed the feeling of "lag" for me. I probably was typing too fast for that setting and it was missing some keystrokes for me.

[tmk]

OK. I confirmed the key drop problem. Slow scan casues it.
See this issue #268 to solve it.

[kevinmost]

Oh, glad I'm not going crazy! I'm going to remove that line and try it out for a few days and see if it makes it better. I think setting the debounce to 0 did make it better but it's still not perfect, so I'll try what you mentioned in #268

[kevinmost]

Seems to be working much better, thanks @tmk for pointing me towards that delay line in the ChibiOS firmware. Everything is working fine with it removed and I'm making a lot less typos!

[flabbergast]

I'll have a look at the original hid_listen/console problem (on a freescale board with a hw debugger) soon.

I also apologise for the needless delay in the main loop - I put it there pretty much during the development just so that the firmware doesn't "needlessly" run a full busy wait loop; I even documented it somewhere, but then forgot about it. When I saw this issue I realised that that's the problem, but you guys are faster ;)
