Ventilo sur GPIO - Raspberry Pi Forums

-

salut à tous,

pour commencer je précise que je ne suis pas un expert des ports gpio sur le rpi !
enfaîte la question est toute simple, j'ai alimenté un petit ventilo en utilisant une pin 5v et une masse et j'aimerai savoir s'il est possible de paramétrer le 5v. je m'explique, je voudrai que le 5v soit dispo sur la broche uniquement lorsque le rpi est booté (pour le moment il suffit de l'alimenter pour avoir le 5v en sortie), en effet pour ne pas faire tourner le ventilo inutilement j'aimerai qu'il soit alimenté uniquement quand le système est lancé. pour info je m'en sers comme mediacenter !

merci d'avance !

bonjour,

les sorties 5v du connecteur gpio ne sont pas administrables. plus d'infos sur http://elinux.org/rpi_low-level_peripherals
sinon, faire de recherches sur ce forum, sujet déjà abordé plusieurs fois...

i'm looking way roaming = 0 in lan, can't figure how it... i'm looking in hostpd.conf , here 802.11r / iapp etc... has managed roaming = 0 system? got lan multiple wired pi ap running in bridge mode eth0 , wlan0. separated ssid, , time change 1 other long. please advice me, thanks. br i have not tried setting pi access point wireless admin , note seem saying each pi has separate ssid. mean device needs learn every pi's ssids , not roam new pi until connection previous 1 gets bad, @ point device re authenticate next pi, causing drop , reconnect, not roam. wireless roaming want use extended service set (ess) , have each pi using exact same ssid, client doesn't need reauth or , can associate same ssid different pi. of course want make sure each pi set different wireless channel don't interfere each other. sorry can't offer more point in right direction. raspberrypi
