TrackPoint support

[tmk]

Just for info.

Code sample: https://geekhack.org/index.php?topic=8971.msg2276591#msg2276591 https://github.com/Nephiel/tmk_keyboard/blob/master/tmk_core/protocol/ps2_mouse.c

I tried Nephiels ps2 .c but it keeps my board in bootloader after flashing...

[tmk]

Not sure what you mean, can you rephrase your problem and it's detail is needed. And What s Nephiels?

[tmk]

Opp s, ignore question about Nephiel. I didn't read first post.

Hi Hasu, yes now what I'm trying to do is to sync with your latest upstream/master and see if then I get the new ps2_mouse.c of Nephiel working.. I'm rebasing it just now and actually I see some strange error while compiling my tentboard:

../../tmk_core/common/keymap.c: In function 'keymap_fn_to_action': ../../tmk_core/common/keymap.c:246: internal compiler error: in iterative_hash_expr, at tree.c:5363 Please submit a full bug report, with preprocessed source if appropriate. See <URL:http://sourceforge.net/tracker/?atid=520074&group_id=68108&func=browse> for instructions. make: *** [obj_tentboard/common/keymap.o] Error 1

probably I still missed something.. did some fn_Actions maybe change their name in the meantime? (like in https://github.com/tentator/tmk_keyboard/blob/master/keyboard/tentboard/keymap_tentboard.c)

Kr, tent:wq

[tmk]

Your keymap file is old and not supported in current core, probably. You need to revise it. See current keymap files located in projects under keyboard/ or converter/.

You mentioned bootloader in earlier comment, what is/was your problem actually?

[tentator]

well a part that change towards "action_t" in the fn_actions I couldn't spot any other changes.. or where also keynames or action_function names changed? I can check out my file maybe -> https://github.com/tentator/tmk_keyboard/blob/master/keyboard/tentboard/keymap_tentboard.c ?
Anyway what happened with the new ps2_mouse.c is that after flashing the teensy utility kept saying that it will disable it to prevent continuous reboots into bootloader and I tryed several compilations and trys but only going back to the older would make the keyboard come back to live.. thus now I was thinking to merge your latest changes into mine and check again...

[tmk]

Yes, use action_t and other part of your keymap looks fine. if you still get 'internal compiler error' try make clean. If it doesn't help I'd reccomend trying other versions of gcc.

[tentator]

HI Hasu, yes I tried clean and with action_t but I think you are right when you say there's something strange with the compiler, I'm using avr-gcc and I'm under windoze and even if I compile something from your directory, latest fetch, I get errors, so it seems to be the gcc to be problematic.. but why only in recent versions? it was ok with older tmk from may or so..?

(this is by compiling your hhkb for instance)

what gcc would you suggest I could use? it needs to cross compile, right?

[tentator]

I also tried to do compile in the "hbkb directory and do a make -f Makefile.lufa" and in this one I got a full compilation without errors..... uhm.....

[tmk]

no idea :( File new issue for this if needed. I don't think Trackpoint code causes your problem.

Old version of avr-gcc may cause problem like that, many people have had problem with WinAVR, in particular. Check this. https://github.com/tmk/tmk_keyboard/wiki#build-firmware

[tentator]

Well what do you mean with old version? I think the latest is WinAVR-20100110. Is there an alternative (for windows)? I have win7 . No virtualbox nor ubunto4windows (unless that works on win7) but have git-bash. .

[tmk]

check this issue #378 TLDR; it is too old and have not been maintenanced for long time. Don't use WinAVR anymore.

[tentator]

Hello Hasu, thanks for the hint but I think in the meantime I found the "bug" and with following fix it should continue to safely run also with winavr-gcc:

(change [...]/tmk_core/common/keymap.c:246 to look like this one instead) return (action_t){ .code = pgm_read_word(&fn_actions[FN_INDEX(keycode)]) };

What do you think about it? I think this was how it was solved in the past as well, if you think it's a fair fix you can take it over in the core or I can submit you a pull request or so.

[tentator]

and by the way the ps2_mouse.c with the trackpoint configurations that set tap to click etc now also work flawlessly.. maybe I still have to understand well why most of the times when I enter bootloader mode my teensy flash tool with that green autoprogram button does not flash it...
