idee per velocizzare ricerca dati in array?

salve ragazzi, mi chiedevo se esiste un metodo più veloce per la ricerca di un dato all'interno di un'array, io sto usando cicli ed if per cercare all'interno dell'array se un valore vi è contenuto tra due dati contigui, esempio:   code: [select] myarray[10]={5,10,20,30,40,50,60,70,80,90}; for (i==0; i<10; i++) { if (valore_ricercato > myarray[ ]  &&  valore_ricercato < myarray[ + 1 ] ) val_ricercato_inf = myarray[ ]; val_ricercato_sup = myarray[ + 1 ]; } } questo metodo mi funziona bene, ma vedo che risulta alquanto lento (relativamente) specie se il dato si trova in fondo, con 16 dati (dichiarati byte), ottengo un tempo di esecuzione da circa 30 80 in base alla posizione dove il dato si trova, sono curioso di vedere se esiste un metodo più efficace per ottenere le info spendendo il minor tempo possibile. ringrazio in anticipo tutti coloro che interverranno con suggerimenti ! grazie dipende da come sono ordinati dati nell

programmation

hello! voilà,je vais suivre le mode d'emploi d'un site (http://mchobby.be/wiki/index.php?title=adafruit_pwm_driver) qui consiste à programmer 2 servos grâce à un "adafruit controleur pwm servo 16 canaux 12 bits - i2c interface - pca9685" et le yun arduino mais, après, je voudrais faire en sorte que grâce, au joystick de la arduino esplora, je puisse donner mes instructions aux 2 servos pour qu'il les effectue. comment vais-je tout programmer ? connecter quoi ? où ? comment ? avant de penser à la suite fais déjà ce que tu prévu   et fais le brique de base par brique de base. quand toutes les briques seront ok, assemble les. quand à faire évoluer, le moment venu  compte tenu de l'expérience emmagasinée tes questions seront différentes et plus précises.

Hulp met bouwen emulator. - Raspberry Pi Forums

hallo allemaal, binnenkort wil ik samen met een vriend een (retro)emulator bouwen voor lanparties met andere vrienden. zo zijn wij bij de raspberry gekomen. hebben geen ervaring met de raspberry maar zijn welkom voor een uitdaging. hebben al uren op google gespeurd maar sommige vragen blijven onbeantwoord: 1. wie kan ons zwart op wit vertellen wat het grootste verschil tussen retropie en recalbox is? 2. begrepen dat niet elk spel soepel werkte. dit ook van toepassing bij het nieuwste model met overclocking? zijn van plan het nieuwste model te gebruiken met natuurlijk voldoende koeling. 3. het mogelijk om een "ademende" led te maken met één van de gpio pinnen? 4. het mogelijk om de raspberry te starten en af te sluiten met de powerbutton op de wiimote of dualshock? 5. het mogelijk dat er een led gaat branden als er op één van de usb poorten iets wordt aangesloten? 6. hoe kan ik dit script automatisch starten op de achtergrond en beïnvloed dit veel de prestaties van de
