 Posted: Mon Apr 17, 2006 3:40 pm Post subject: [telecommande] 2 touches ne marchent pas ( resolu) |
 |
|
Salut a tous et joyeuses paques à vous.
J'ai une telecommande ATI REMOTE USB qui fonctionne normalement avec le module du noyau et est donc reconnue comme un clavier. Toutes les touches fonctionnent sauf les touches CHANNEL - et CHANNEL + ( à cote du bouton MUTE). Sous X, aucune réponse avec xev. Par contre en console, avec showkey, je peux récupérer le keycode mais pas le scancode!
| Code: |
#showkey
kb mode was XLATE
press any key (program terminates 10s after last keypress)...
keycode 28 release
keycode 403 press
keycode 403 release
keycode 403 press
keycode 403 release
keycode 402 press
keycode 402 release
|
Les keycodes des touches sont 403 et 402 ( ce qui me parait bizzare soit dit en passant)
Par contre, showkey -s ne renvoie pas les scancodes quand j'appuie sur ces mêmes touches.
Donc, si vous avez des suggestions n'hésitez pas.
Ma config:
gentoo-sources-2.6.16 avec le module ati_remote

Pareil, j'ai le même problème.
Mais je sais que ces touches fonctionnaient parfaitement avec un noyau 2.6.10
Donc, ce que j'avais fait à une époque, j'avais été rechercher le module ati_remote dans un nouveau fraichement compilé, et j'avais été le foutre à la place du module de mon noyau 2.6.15
C'est tout à fait fesable, et ça avait marché.
Mais depuis, j'ai réinstallé le système, et j'ai plus eu le courage de refaire la manip. Je n'utilise tout simplement plus ces 2 boutons là ... |

Un petit up 
J'ai pas mal cherché sur le net et dans les docs de showkey ainsi que les sources du noyau mais je ne vois pas ce qu'il faut modifier pour que ca marche.
Si vous avez une idée sur la démarche à adopter pour résoudre le problème, ne soyez pas timide  |

Ca y est, j'ai resolu le probleme. En fait, j'ai bidouillé le module ati-remote.c du noyau. J'explique la démarche que j'ai suivie ( ça peut toujours servir pour des cas similaires). En regardant ce code source, j'ai vu qu'il y avait une option de debugage non activée par defaut. Je l'ai mise en faisant:
| Code: |
rmmod ati_remote
insmod /lib/modules/2.6.16-gentoo-r2/kernel/drivers/usb/input/ati_remote.ko debug=1
|
Ainsi on peut voir les événements liés à la telecommande dans les messages du noyau avec
| Code: | | tail -f /var/log/messages |
En faisant pas mal de tests, j'ai vu qu'il y avait 5 touches( TV, DVD, CHAN-, CHAN+ et OK) qui ne fonctionnaient pas à l'arrivée mais elles envoyaient des événements. D'après le source, elles devaient envoyer des keycodes, KEY_TV, KEY_DVD... qui avaient tous des valeurs élevées (>240) alors que les autres touches envoyaient des keycodes <240 d'après le fichier /usr/src/linux-2.6.16-gentoo-r2/include/linux/input.h . Le probleme venait donc de là à priori
J'avais 2 possibilités: modifier /usr/src/linux-2.6.16-gentoo-r2/include/linux/input.h qui définit l'ensemble des keycodes utilisables pour les claviers, souris, ... du système ou modifier uniquement le module pour qu'il demande d'autres keycodes plus petits pour ces touches non utilisables. J'ai préféré la deuxième solution car elle est moins "risquée" et au pire la télécommande ne marche plus tandis qu'avec la première, tous mes périphériques d'entrée auraient pu ne plus marcher.
Bref, voilà le résultat de mes réflexions tardives

* USB ATI Remote support
*
* Version 2.2.0 Copyright (c) 2004 Torrey Hoffman <thoffman@arnor.net>
* Version 2.1.1 Copyright (c) 2002 Vladimir Dergachev
*
* This 2.2.0 version is a rewrite / cleanup of the 2.1.1 driver, including
* porting to the 2.6 kernel interfaces, along with other modification
* to better match the style of the existing usb/input drivers. However, the
* protocol and hardware handling is essentially unchanged from 2.1.1.
*
* The 2.1.1 driver was derived from the usbati_remote and usbkbd drivers by
* Vojtech Pavlik.
*
* Changes:
*
* Feb 2004: Torrey Hoffman <thoffman@arnor.net>
* Version 2.2.0
* Jun 2004: Torrey Hoffman <thoffman@arnor.net>
* Version 2.2.1
* Added key repeat support contributed by:
* Vincent Vanackere <vanackere@lif.univ-mrs.fr>
* Added support for the "Lola" remote contributed by:
* Seth Cohn <sethcohn@yahoo.com>

* Hardware & software notes
*
* These remote controls are distributed by ATI as part of their
* "All-In-Wonder" video card packages. The receiver self-identifies as a
* "USB Receiver" with manufacturer "X10 Wireless Technology Inc".
*
* The "Lola" remote is available from X10. See:
* http://www.x10.com/products/lola_sg1.htm
* The Lola is similar to the ATI remote but has no mouse support, and slightly
* different keys.
*
* It is possible to use multiple receivers and remotes on multiple computers
* simultaneously by configuring them to use specific channels.
*
* The RF protocol used by the remote supports 16 distinct channels, 1 to 16.
* Actually, it may even support more, at least in some revisions of the
* hardware.
*
* Each remote can be configured to transmit on one channel as follows:
* - Press and hold the "hand icon" button.
* - When the red LED starts to blink, let go of the "hand icon" button.
* - When it stops blinking, input the channel code as two digits, from 01
* to 16, and press the hand icon again.
*
* The timing can be a little tricky. Try loading the module with debug=1
* to have the kernel print out messages about the remote control number
* and mask. Note: debugging prints remote numbers as zero-based hexadecimal.
*
* The driver has a "channel_mask" parameter. This bitmask specifies which
* channels will be ignored by the module. To mask out channels, just add
* all the 2^channel_number values together.
*
* For instance, set channel_mask = 2^4 = 16 (binary 10000) to make ati_remote
* ignore signals coming from remote controls transmitting on channel 4, but
* accept all other channels.
*
* Or, set channel_mask = 65533, (0xFFFD), and all channels except 1 will be
* ignored.
*
* The default is 0 (respond to all channels). Bit 0 and bits 17-32 of this
* parameter are unused.
*

Les modifs sont entre les lignes 231 et 268. Pour l'utiliser, il suffit de sauvegarder l'ancien et de mettre celui-la à la place puis un make modules;make modules_install depuis /usr/src/linux. Puis avec "xbindkeys -mk" de trouver les keycodes des 5 touches qui ne marchaient pas (TV, DVD, CHAN-, CHAN+ et OK) et de remplacer dans .xbindkeysrc les keycodes qui etaient eventuellement presents pour ces touches.
Voili, voilou

Yep
merci bob1977 pour la modif du driver!!
Le truc c'est que j'ai recompilé le module avec le nouveau driver et tout à marché comme sur des roulettes!
Donc je suis allé manger tranquil!! Je retourne sur mon PC et la paff pastek!!! les retour de key code sont
alors que j'atais pourtant sur que j'avais ça avant de passer a table:
je suis pas le seul ICI aussi
quelqu'un voie d'ou ça peut venir? |

Salut mccm,
Je suis content que ma modif du module ait ete utile à quelqu'un!.
Pour ton probleme, il suffit de dupliquer le contenu de .xbindkeysrc en remplacant tes 0x0 en 0x10 dans la 2eme partie.
Petite info: vu que je n'ai aucune utilite de la fonction souris ou des touches qui emulent le clavier, j'ai fait une autre modif du module pour qu'il ne renvoie aucun keycode correspondant à une touche d'un clavier classique. Afin d'exploiter toutes ces nouvelles touches disponibles pour lancer des commandes, j'ai fait quelques scripts ( mais pas tous finis) qui permettent de gerer plusieurs modes audio ( son 5.1, stereo, TV ) , de lancer plusieurs sessions de xmms et de bien le controler , de lancer xdtv et mplayer et tout ca avec un affichage osd. Pour l'instant, la gestion audio et xmms marche mais je suis bloqué sur un pb de syntaxe bash pour passer plusieurs commandes en parametres d'un script. Des que ca marchera, je le mettrais sur le forum. |

hello bob1977
le truc c'est que c'est aléatoire un coup m:0x0 un autre m:0x10 enfin je voir ça je te tiens au jus

Salut mccm,
Je pense que tu n'as pas compris. Tu dupliques le fichier .xbindkeysrc dans lui-meme. Selectionne tout le contenu, cpoy puis paste à la fin du fichier. Dans cette partie du fichier tu remplaces les 0x0 par des 0x10 ou l'inverse selon ce que tu n'as pas mis encore.
Comme ca, tu n'as plus besoin de faire attention au si ta telecommande est reconnue en 0x0 ou 0x10.
J'espere que c'est plus clair comme ca. |
