Apr\u00e8s avoir re\u00e7u la MaixGo<\/a> et l’avoir mont\u00e9e, il faudrait commencer \u00e0 faire quelque chose avec. <\/p>\n\n\n\n

Tout d’abord, comme \u00e7a fait un an et demi qu’elle traine sur mon \u00e9tag\u00e8re, une bonne id\u00e9e serait de la mettre \u00e0 jour.<\/p>\n\n\n\n

Mais \u00e0 quoi peuvent bien servir autant de micros sur une m\u00eame carte \u00e9lectronique ? <\/p>\n\n\n\n
\u00c0 faire de la localisation de source sonore pardi. Pour faire cela, je n’invente rien. Il suffit de reprendre le script propos\u00e9 par chegewara sur son github<\/a> (avec quelques suppressions de lignes inutiles dans le cas du MaixGo):<\/p>\n\n\n

On peut bien sur copier\/coller les lignes du script une par une. Mais c’est tr\u00e8s p\u00e9nible, surtout que la moindre erreur de frappe ne peut pas \u00eatre corrig\u00e9e.<\/p>\n\n\n\n
Non pour se simplifier la vie on peut passer en mode \u00abpaste\u00bb avec Ctrl+e<\/strong>. un peu comme dans vim, il ne prendra le texte que de mani\u00e8re \u00abbrute\u00bb sans mise en forme. On termine sa session de collage avec la touche Ctrl+d<\/strong>.<\/p>\n\n\n
