More steering wheel controls

[liamstears]

Bare with me as I might be totally off base but fingers crossed the logic is sound

So basically in my car I have multiple canbus buttons I would like to map but using the Raise VW(PQ) option I believe the limitation is within the head unit to the following buttons:

SWC_KEY_VOLUME_UP = 0x01;
SWC_KEY_VOLUME_DOWN = 0x02;
SWC_KEY_MENU_UP = 0x03;
SWC_KEY_MENU_DOWN = 0x04;
SWC_KEY_TEL = 0x05;
SWC_KEY_MUTE = 0x06;
SWC_KEY_SRC = 0x07;
SWC_KEY_MIC = 0x08;

SWC_KEY_TO_USER_KEY_TABLE.put(SWC_KEY_VOLUME_UP, VehiclePropertyConstants.USER_KEY_VOLUME_UP);
SWC_KEY_TO_USER_KEY_TABLE.put(SWC_KEY_VOLUME_DOWN, VehiclePropertyConstants.USER_KEY_VOLUME_DOWN);
SWC_KEY_TO_USER_KEY_TABLE.put(SWC_KEY_MENU_UP, VehiclePropertyConstants.USER_KEY_DOWN);//上下取反
SWC_KEY_TO_USER_KEY_TABLE.put(SWC_KEY_MENU_DOWN, VehiclePropertyConstants.USER_KEY_UP);
SWC_KEY_TO_USER_KEY_TABLE.put(SWC_KEY_TEL, VehiclePropertyConstants.USER_KEY_BLUETOOTH);
SWC_KEY_TO_USER_KEY_TABLE.put(SWC_KEY_MUTE, VehiclePropertyConstants.USER_KEY_MUTE);
SWC_KEY_TO_USER_KEY_TABLE.put(SWC_KEY_SRC, VehiclePropertyConstants.USER_KEY_SOURCE);
SWC_KEY_TO_USER_KEY_TABLE.put(SWC_KEY_MIC, VehiclePropertyConstants.USER_KEY_VOICE);

However I have found this link: https://github.com/darkspr1te/Work/blob/master/MctCoreServices/src/com/mct/carmodels/RZC_ToyotaSeriesProtocol.java

This shows a lot more available buttons which the head unit should understand:

SWC_KEY_VOLUME_UP = 0x01;
SWC_KEY_VOLUME_DOWN = 0x02;
SWC_KEY_MENU_RIGHT = 0x03;
SWC_KEY_MENU_LEFT = 0x04;
SWC_KEY_SRC = 0x07;
SWC_KEY_SPEECH = 0x08;
SWC_KEY_PICK_UP = 0x09;
SWC_KEY_HANG_UP = 0x0A;
SWC_KEY_BOX = 0x0B;
SWC_KEY_MENU_UP = 0x13;
SWC_KEY_MENU_DOWN = 0x14;
SWC_KEY_BACK = 0x15;
SWC_KEY_ENTER = 0x16;
SCROLL_KEY_VOLUME_UP = 0x81;
SCROLL_KEY_VOLUME_DOWN = 0x82;
SCROLL_KEY_CH_FLD_UP = 0x83;
SCROLL_KEY_CH_FLD_DOWN = 0x84;
SCROLL_KEY_TUNE_TRACK_UP = 0x85;
SCROLL_KEY_TUNE_TRACK_DOWN = 0x86;
SWC_KEY_POWER = 0x87;
SWC_KEY_MODE = 0x88;

SWC_KEY_TO_USER_KEY_TABLE.put(SWC_KEY_VOLUME_UP, VehiclePropertyConstants.USER_KEY_VOLUME_UP);
SWC_KEY_TO_USER_KEY_TABLE.put(SWC_KEY_VOLUME_DOWN, VehiclePropertyConstants.USER_KEY_VOLUME_DOWN);
SWC_KEY_TO_USER_KEY_TABLE.put(SWC_KEY_MENU_LEFT, VehiclePropertyConstants.USER_KEY_UP);//VehiclePropertyConstants.USER_KEY_LEFT);
SWC_KEY_TO_USER_KEY_TABLE.put(SWC_KEY_MENU_RIGHT, VehiclePropertyConstants.USER_KEY_DOWN);//VehiclePropertyConstants.USER_KEY_RIGHT);
SWC_KEY_TO_USER_KEY_TABLE.put(SWC_KEY_SRC, VehiclePropertyConstants.USER_KEY_SOURCE);
SWC_KEY_TO_USER_KEY_TABLE.put(SWC_KEY_SPEECH, VehiclePropertyConstants.USER_KEY_VOICE);
SWC_KEY_TO_USER_KEY_TABLE.put(SWC_KEY_PICK_UP, VehiclePropertyConstants.USER_KEY_PHONE_ACCEPT);
SWC_KEY_TO_USER_KEY_TABLE.put(SWC_KEY_HANG_UP, VehiclePropertyConstants.USER_KEY_PHONE_HANGUP);
SWC_KEY_TO_USER_KEY_TABLE.put(SWC_KEY_BOX,VehiclePropertyConstants.USER_KEY_HOME);
SWC_KEY_TO_USER_KEY_TABLE.put(SWC_KEY_MENU_UP, VehiclePropertyConstants.USER_KEY_UP);
SWC_KEY_TO_USER_KEY_TABLE.put(SWC_KEY_MENU_DOWN, VehiclePropertyConstants.USER_KEY_DOWN);
SWC_KEY_TO_USER_KEY_TABLE.put(SWC_KEY_BACK, VehiclePropertyConstants.USER_KEY_BACK);
SWC_KEY_TO_USER_KEY_TABLE.put(SWC_KEY_ENTER, VehiclePropertyConstants.USER_KEY_OK);
SWC_KEY_TO_USER_KEY_TABLE.put(SCROLL_KEY_VOLUME_UP, VehiclePropertyConstants.USER_KEY_VOLUME_UP);
SWC_KEY_TO_USER_KEY_TABLE.put(SCROLL_KEY_VOLUME_DOWN, VehiclePropertyConstants.USER_KEY_VOLUME_DOWN);
SWC_KEY_TO_USER_KEY_TABLE.put(SCROLL_KEY_CH_FLD_UP, VehiclePropertyConstants.USER_KEY_UP);
SWC_KEY_TO_USER_KEY_TABLE.put(SCROLL_KEY_CH_FLD_DOWN, VehiclePropertyConstants.USER_KEY_DOWN);
SWC_KEY_TO_USER_KEY_TABLE.put(SCROLL_KEY_TUNE_TRACK_UP, VehiclePropertyConstants.USER_KEY_RADIO_STEP_UP);
SWC_KEY_TO_USER_KEY_TABLE.put(SCROLL_KEY_TUNE_TRACK_DOWN, VehiclePropertyConstants.USER_KEY_RADIO_STEP_DOWN);
SWC_KEY_TO_USER_KEY_TABLE.put(SWC_KEY_POWER, VehiclePropertyConstants.USER_KEY_POWER);
SWC_KEY_TO_USER_KEY_TABLE.put(SWC_KEY_MODE, VehiclePropertyConstants.USER_KEY_MODE);

So my theory is that if we emulate as this Toyota instead of the VW I could potentially remap keys to any of the above? This would be great if I could map some back and home buttons as well as having proper accept and hangup buttons too

What do you think?

I am willing to test this...

@smartgauges I would really appreciate your input on this. To be honest I could add the extra protocol myself it looks pretty simple in the code but I'm stuck because I know for VW PQ for example you use "e_cb_raise_vw_pq" but what would be correct for this Toyota series protocol?

[erik-rosen]

I'm going to try creating support for the raise toyota canbox protocol and test it out with my DUDU7 head unit to see if I can make use of all of the nav buttons on my XC90 - will let you know how it goes.

Seems like this protocol doesnt have prev and next though. I think I'll just have to see what these different commands do on the headunit to see if they make sense to map to the nav buttons or prev/next buttons on the steering wheel:

SCROLL_KEY_CH_FLD_UP = 0x83;
SCROLL_KEY_CH_FLD_DOWN = 0x84;
SCROLL_KEY_TUNE_TRACK_UP = 0x85;
SCROLL_KEY_TUNE_TRACK_DOWN = 0x86;
SWC_KEY_MODE = 0x88;

I believe

SWC_KEY_MENU_UP = 0x13;
SWC_KEY_MENU_DOWN = 0x14;

Would be your next/prev buttons, very much interested in how this goes, if you need any help or a tester I'd be happy to

[erik-rosen]

With Raise-Totoya-ALL/HIAMP protocol in my DUDU7 head unit:

SWC_KEY_MENU_UP = 0x13; and SWC_KEY_MENU_LEFT = 0x04 are equivalent and changes to previous song
SWC_KEY_MENU_DOWN = 0x14 and SWC_KEY_MENU_RIGHT= 0x03 are equivalent and changes to next song

Not sure the nav button support in these head units are that built out :p

[erik-rosen]

SWC_KEY_MENU_BACK = 0x15 - Seems to shut down the app (or sleep the screen)
SWC_KEY_MENU_ENTER = 0x16 - Toggles play

Below also just changes tracks (next previous):
SCROLL_KEY_CH_FLD_UP = 0x83;
SCROLL_KEY_CH_FLD_DOWN = 0x84;
SCROLL_KEY_TUNE_TRACK_UP = 0x85;
SCROLL_KEY_TUNE_TRACK_DOWN = 0x86;

Nice and thanks for the update, are you able to share your code changes so I can have a play too? Were you able to get everything else working that I said works because if not I can double check my code see if anything differs from what you already have available...

hi @liamstears, the number of supported buttons depends on the car model, adapter manufacturer and head unit
you can look here to find information about raise and hiworld adapter protocols on different cars
