bonjour, je souhaite créer une alarme très peu complexe à base de raspberry. je possède le modèle b+. j'ai malheureusement quelques soucis avec ce projet: 1- les branchements: je pense brancher mon détecteur magnétique sur le pin1 et le pin7 du gpio avec une résistance de pull-down. 2- mon code: (je pense qu'il y des erreurs ) je ne m'y connais pas très bien en codage mais j'apprends. je ne sais pas comment faire pour pouvoir désactiver l'alarme avec un code numérique tapé sur le clavier connecté au raspberry. la sirène sera diffusé sur les enceintes connectées en jack. voici mon code (alarme pi.h) code: select all //input.c #include <bcm2835.h> #include <stido.h> #define pin rpi_gpio_p1_15 int main(int argc, char ** argv) { if (!bcm2835_init()) { return 1; } // fixe le gpio en entrée bcm2835_gpio_fsel(pin, bcm2835_gpio_fsel_inpt); // avec une résistance de pull down bcm2835_gpio_set_pud(

PS CS4 Pfade Punkte löschen

ich habe bei photoshop cs4 das problem, dass beim auswählen einzelner punkte eines pfades oft der ganze pfad und nicht die angewählten punkte gelöscht werden. bisher habe ich noch nicht verstanden, wann und wodurch das passiert. ohne es mit cs4 getestet zu haben, der beliebte fehler: auswahlwerkzeug (schwarzpfeil) statt direktauswahlwerkzeug (weißpfeil) genommen? oder eine unangenehme eigenschaft: wenn erst der gesamte pfad selektiert war und man geht dann aufs direktauswahlwerkzeug, kann es passieren, dass alle punkte ausgewählt sind. in diesem fall durch klicken außerhalb des pfades alles deselektieren und dann nur den betreffenden punkt selektieren. löschen von punkten geht im ürbrigen meist einfacher, wenn man einfach beim pfadwerkzeug bleibt. befindet man sich damit über einem existierenden punkt, verwandelt sich das icon in einen minus-füller. klicken und weg ist der betreffende punkt.

Acrobar Reader auf Sehbehinderten-Arbeitsplatz &#9472; wer kent eine Lösung ?

liebe acrobat-anwendergemeinde, die zunehmende verbreitung von pdf-dateien prodiziert inzwischen massive ergomomie-probleme, die auch gewerberechtliche konsequenzen nach sich ziehen können. die reader-hilfe schweigt sich leider darüber aus, wie man die ansicht per tastatur ohne veränderung des dokuments/formulars einstellen kann, daß helle schriften auf dunklem grund präsentiert werden. der weiße untergrund von aansichten im normalzustand ist derart grellweiß, daß die betroffenen auch in den nachbarfeldern des dunklen rahmens nichts lesen und auch nicht den mauszeiger positionieren können. die lupenfunktion kann das problem nicht lösen. ebenso unbefriedigend verliefen versuche der umwandlung in doc- und txt-dateien. wenn die sache nicht mit adobe-mitteln zu regeln ist: gibt es vielleicht von anderen firmen entsprechende add-ons, die auch mit auflösung 640*480 einwandfrei arbeiten ? vielen herzlichen dank und viele schöne grüße gottfried stigge universitäts-klinikum heidelberg medizin
