hello, pour un montage, j'ai besoin d'un bus i2c pour communiqué avec un lcd et des interfaces relais, ou autre.. mais j'ai aussi besoin d'un module rtc, mais je vois que ça utilise aussi le pins dédier l'i2c, mais ne fonctionnement pas de la même façon. ma question est : puis utilisé le i2c et le rtc simultanément ? merci quote from: gruniek on jun 16, 2014, 04:51 pm ...mais je vois que ça utilise aussi le pins dédier l'i2c, mais ne fonctionnement pas de la même façon. plus de détails peut-être ?

hello. long time lurker first time poster. did read how , i'm trying adhere rules as possible. if i'm in error in 1 of them please let me know. i have watering program. there bunch more code in trying debug i've removed of code can make sure there isn't else causing problem. it's worked me before in solving problems time code simple can , i'm still getting error. the object trying create irrigation valve. valve have, now, 3 attributes. have pin energizes valve, duration how long active, , setpoint once surpassed activate valve, after return zero. want initialize attributes , store them in private section? of class. first time i've created library , class perhaps can point me toward i'm making mistake in syntax or initialization. know i'm not supposed excessively use defines , in future user prompted @ setup define these parameters in addition many other valves added use them during prototyping simplicity. did fail create object? if syntax s

i play bass-synth (minimoog voyager) in kraftwerk-like band , since we´re "just standing there" thought it´d idea give songs different light effects give them more of individual visual feel. thought i´d use arduino this, though i´ve never been close programming before that´s quite threshold me. soldering , circuits more familiar. first i´ll starting simple 1 board of white leds flash press key , 1 board of leds rows lit in sequence wave when press key. i´ve finished boards, , i´ve succesfully tried programming series of leds lighting up. got find out how use midi shield bought , midi library (which have absolutely no clue how use). appreciated!!! here´s code "wave-leds" i´ll use start. when i´ve figured out hope make run once , start on if key pressed. i´m pleased if can sequence started pressing key on moog. code: [select] int switchstate=0; void setup(){ pinmode(3,output); pinmode(4,output); pinmode(5,output); pinmode(6,output); pinmode(7,output); pinmod
