hi, I was wondering if anyone knew how to change the keyboard layout on the teensy?

heres the problem: supposed to print:

cmd /c for /F %i in ('WMIC logicaldisk where \"DriveType=2\" list brief ^| find \"LABEL\"') do %i\\whatever.txt

but instead prints:

cmd /c for /F %i in ('WMIC logicaldisk where @DriveType=2@ list brief ^~ find @LABEL@') do %i#whatever.txt

I have tryed various things to get it to work. mainly making it fail compiling.

anyone have any ideas/tutorials etc.?

I am totally lost!

Have you tried sending the special characters like this

Keyboard.set_key1(KEY_TILDE);
Keyboard.send_now();
Keyboard.set_key1(0); // reset key state
Keyboard.send_now();

Other keycodes here http://www.pjrc.com/teensy/td_keyboard.html

Short of this, you could poke around in path\hardware\teensy\cores\teensy_hid

cheers, yea I thought about doing it that way... but uses too much code,

have email'd Paul Stoffregen

who said:

Look inside your Arduino folder for a file named usb.c... the one in the "teensy_hid" area, not the serial one. Inside, you'll find all the descriptor data which the PC reads when it detects the USB device. You'll find this:
// HID interface descriptor, HID 1.11 spec, section 6.2.1

9, // bLength

0x21, // bDescriptorType

0x11, 0x01, // bcdHID

0, // bCountryCode

1, // bNumDescriptors

0x22, // bDescriptorType

sizeof(keyboard_hid_report_desc), // wDescriptorLength

You might try changing the bCountryCode line....

I found the codes here

http://www.usb.org/developers/devclass_docs/HID1_11.pdf

page 33

and I changed:

C:\Program Files\arduino-0018\hardware\teensy\cores\teensy_hid\usb.c

line 195

line 222

line 249

I have tried 33 (usa), 32 (uk) & 13 (international ISO)

However none of them changed the output?

I have re-emailed him and were trying to work it out, if you or anyone else out there has any ideas it would be loads of help :D

Sl45h3R · May 2, 2010

If you change it, im pretty sure you have to recompile the library?

NanoyMaster · May 2, 2010

ok, that makes sence.

but how? just usb.c or everything in that directory. and where would it be compiled to?

arduino doesn't seem to have many .exe's anywhere?!?!

/me gets to google

Sl45h3R · May 2, 2010

Arduino's library's aren't exe files, as it runs cross platform. Im not sure, maybe reply to the email and ask Paul.

NanoyMaster · May 2, 2010

Those numbers are compile-time constants, which are placed into arrays of bytes stored in read-only flash memory

so there automaticaly compiled when you "verify" you code in arduino

ref. http://www.hak5.org/forums/index.php?showt...=16258&st=0

that means you should just be able to save them, also have tryed 0x<no> aswell as just <no>

makes no difference :S

unrealdude · May 2, 2010

i would like to suggest that a goal be added that intends to result in the ability to switch keyboard layouts at runtime based upon DIP switch settings

NanoyMaster · May 2, 2010

woa there cowboy...

lets just see if we can actually change it first :D

but yea that would be an awesome idea! I think it's one of them "easier said than done" things tho :(

unrealdude · May 2, 2010

i think it would be easier that it seems, just figure out what code u must send to reach the end result and write a func that translates it (quick and dirty method)

i shall be working on this during the coming week (slowly) as i use a customized dvorak layout

Edited May 2, 2010 by unrealdude

NanoyMaster · May 3, 2010

OK, I have discovered that by changing usb_api.cpp

line 38 - 166

you can change the layout

now it's just a case of trial and error until it's right -.-' *sigh*

NanoyMaster · May 3, 2010

OK so I have got this far and am now stuck

a-z,A-Z,0-9 work fine

symbols should come out like

!"£$%^&*()_,+-=: @#~<>{}?|¬`'\/.;

but come out like

!"£$%^&*()_,+-=:@#~~<>{}?`'#/.;

need to fix (space, the extra ~, | (pipe?) and ¬ (no idea what ¬ is¬))

heres my usb_api.cpp so far.. yes I know it's messy!

--UPDATE--

after that not working I decided to take another route:

I have discovered by using:

for (x = 47; x <= 50; x++){ //Psychosis's idea... and a good one at that!

Keyboard.print(x);Keyboard.print(": ");

Keyboard.set_key1(x);

Keyboard.send_now();

Keyboard.set_key1(0);

Keyboard.send_now();

Keyboard.print("\r");

delay(100);

}

that instead of \ it's putting #

I managed to change " with @ by changing usb_api.cpp

also when it tries to do KEY_BACKSLASH it does #

no matter what the country code is in usb.c

I am totally lost

any help you could give would be greatly appreciated

Deevd · May 28, 2010

Hi I am belgian,

so keyboard layout is verry different.

Did you find a solution or not?

Thx in advance

NanoyMaster · May 29, 2010

No I still havn't gotten it to work :( gave up with the teensy for now as this is way beyond my capabilities (and it was driving me insane)

I don't think there is an easy way to get it to work in different layouts.

and the bcountrycode vars just doesn't do anything.

If you have any more luck than me it would be great :D or any ideas that I might have missed?

I don't think it's just a case of swapping them around since some times 2 chars produce the same output and a load of other weird things happen :(

Deevd · May 29, 2010

yeah found out swapping them was no good solution...

instead i tried working on a sort of adaptor... that would read the

string with my normal BE layout, and gives back a modified string back

which replaces the symbols by those needed to make a good output...

But for the moment i'm in a little struggle, will let you know if I finally get it to work...

IOSys · May 29, 2010

just a thought .. couldn't you type ASCII-codes on the num-pad ?

NanoyMaster · May 29, 2010

you could with alt+<no.s>

but it would be nice if the usb HID device (usb keyboard) could actually type keyboard chars in out layouts

plus that makes more code than nessicary eg.

to print alt+123 you would have to:

1) press alt

2) set 1

3) send 1

4) release 1

5) set 2

6) send 2

7) release 2

8) set 3

9) send 3

10) release 3

11) release alt

seems a bit overkill for sending an "@" for example

Deevd · May 29, 2010

I had the perfect plan, was coding a test in MinGW,

just to test out... had it working nicely with Strings and stuff like that...

but when i tried to use strings inside the Teensy libraries it kept saying

that string is not a known name type ...

EDIT:

Ok so had some trouble, but found another way to be able to type the code and text between " " with

my belgian layout, and still getting the right text printed out...

I wrote some code into the usb_api.cpp

I added a method called convert(const char c[]) so it takes a const char[] like println() does,

in this method convert, i read the whole char array and for each charachter it will make the right

Keyboard.set_Key1(...) Keyboard.send_now()....

Till now that's the only sollution I found :)

Had to find out what every key printed out and stuff like that, but finally it's a success !!

NanoyMaster if you need help, send PM ...
