      Salut trop fatiguée pour tester le truc mais j y jete un oeil et oui retropboy a compilé le binaire mais je me demande si il a ajouté le gpio pour le bouton echap lol.

          Salut j'ai pas de clavier peux tu testé si en faisant echap tu sors bien de retroarch ou lui faudrait-il une combinaison de touche aussi avec un clavier ? merci d'avance

            je te confirme, la touche echap du clavier fais bien sortir de l'émulateur pour revenir au menu des émulateurs

                  @Violene merci pour le test. @retroboy merci beaucoup si j'ai bien compris il faut déclarer la touche dans retrogame.c puis lancer le make. J'ai ajouté ceci : GPIO 11

                  {  11,      KEY_ESC       },   // escape, out of emulator
                  
                  /*
                  ADAFRUIT RETROGAME UTILITY: remaps buttons on Raspberry Pi GPIO header
                  to virtual USB keyboard presses.  Great for classic game emulators!
                  Retrogame is interrupt-driven and efficient (usually under 0.3% CPU use)
                  and debounces inputs for glitch-free gaming.
                  Connect one side of button(s) to GND pin (there are several on the GPIO
                  header, but see later notes) and the other side to GPIO pin of interest.
                  Internal pullups are used; no resistors required.  Avoid pins 8 and 10;
                  these are configured as a serial port by default on most systems (this
                  can be disabled but takes some doing).  Pin configuration is currently
                  set in global table; no config file yet.  See later comments.
                  Must be run as root, i.e. 'sudo ./retrogame &' or configure init scripts
                  to launch automatically at system startup.
                  Requires uinput kernel module.  This is typically present on popular
                  Raspberry Pi Linux distributions but not enabled on some older varieties.
                  To enable, either type:
                      sudo modprobe uinput
                  Or, to make this persistent between reboots, add a line to /etc/modules:
                      uinput
                  Prior versions of this code, when being compiled for use with the Cupcade
                  or PiGRRL projects, required CUPCADE to be #defined.  This is no longer
                  the case; instead a test is performed to see if a PiTFT is connected, and
                  one of two I/O tables is automatically selected.

                    je penche sur une réalisation du même genre (le reset sur gpio avec un retour sous emulationstation) mon niveau de programmation étant proche de 0 je suis attentif a votre poste si vous arrivez a quelque choses ça m’intéresse 😄 je suis tomber sur un principe quelque peu différent peut être que vous y comprendrait plus que moi 😉 au lieu de passé par ADAFRUIT c'est un script python qui simule l’appuie sur echap   http://carrefour-numerique.cite-sciences.fr/fablab/wiki/doku.php?id=projets:retropie_gpio_additions

                      Bonjour l'idée est intéressante du moment ou tu veux ajouter des boutons. dès que j'ai un moment je testerai. Cependant adafruit va plus loin car il permet de simuler les touches clavier sur les gpio, donc si certains jeux requièrent le clavier il serait donc possible d utiliser un kit joystick placé sur le gpio pour jouer en théorie

                        d'ailleurs, mon projet prends doucement forme.... j'attends encore du matériel pour fixer tout ca proprement...parce que simplement collé, ca me convient pas du tout...

                          Oui je suis bien d'accord Acris Adfruit et plus complet, mais moi qui dans mon cas ne cherche qu'a faire un "retour bureau" c'est peut etre un peu complexe a metre en oeuvre ? Si tu teste je suis preneur de tes conclusion 😉

                              Nop car il me faut un bouton pour tester je dois en récupérer un au travail et avec cette canicule pas trop sur le pc.

                                  photo   mon petit bricolage avance doucement...au fil du matos que la poste me livre... J'ai pu intégrée dans la snes le pi, le retrode, le port manettes d'origine que j'ai bricolé et j'ai meme remis le levier d'ejection des cartouches. il faudra que je le renforce a long terme parce que je l'ai bien aminci pour qu'il prenne sa place. il me reste a recevoir le  LM2596 que j'ai commandé sur amazon afin de pouvoir me servir de l'alim d'origine de la snes... j'aimerais pouvoir utiliser la trappe sous la snes pour déporter le dernier port usb (qui me servirais eventuellement a synchroniser mes manettes ps3 les jours ou j'ai pas envie de trimballer celles de snes. il faut aussi que je branche le bouton power d'origine (sur le LS2596) et le bouton reset sur le GPIO. J'aimerais aussi trouver un moyen de faire briller la led d'origine de la console...je me demande si je fais une simple led power ou si je déporte la led d'activité du pi.... et enfin, trouver un adaptateur usb/snes pour la 2eme manette...puisqu'il semble impossible de déclarer les 2 manettes du retrode ca fait beaucoup de choses, et peu de place...

                                      Salut je ne suis pas familière avec ce type de bricolage si j ai bien compris le LM2596 est un convertisseur et régulateur qui va te permettre de modifier le voltage et l'ampérage de l'alimentation de la snes pour obtenir du 5V 2A ? Je pense que tu dois brancher des fils sur les GPIO genre +5V ET GND parce que je vois pas comment cette "chose" sera relié 😛 Je regarde dès que possible faut juste que je retrouve mon cable bouton (en ce moment je monte des meubles lol)

                                        Le LM2596 me servira a convertir en effet les 9v de transfo d'origine snes en 5v avec une intensité j'espère suffisante....(le transfo snes sors 1.3A, ce qui est peu) si ca marche pas, je prendrais un transfo 9v plus puissant, mais je voulais tenter de garder au maximum la connectique arrière d'origine. pour les branchements du GPIO, nottement du bouton reset, ce sera indépendant. le circuit d'alimentation n'interviendra pas, surtout que le GPIO possède ses propres alimentations bon montage de meubles...

                                          tu as pu tester le bouton reset grace a adafruit acris ? j'arrive a la fin de mon bricolage, il me reste la led a cabler, j'attends de recevoir une résistance de 160 ohm pour la brancher au 5v l'alim a finaliser, j'ai pas pu utiliser le module lm2596, ca rebootait le pi sans arret, je pense que l'intensité dispo en sortie etait trop faible. du coup j'ai commandé une alim 5v avec le connecteur rond de la snes directement. et ce fameux bouton reset, qui, ca me plairais bien quand meme, provoque un retour menu lorsqu'on appui dessus... je ferais un petit récapitulatif photo lorsque tout sera fini

                                            Nop pas testé j etais en vacances la semaine dernière et j ai pas retrouvé mon cable mais j ai pas oublié. on avait pas un problème aussi de gamepad identitiques qui ne fonctionnaient pas via le retrode ? si tu mets les 2 manettes snes il y en a qu'une seule qui fonctionnent ? j ai pas relu les 8 pages 😛
