bonjour, j'ai efféectué un petit programme arduino pour gérer un asservissemement en position qui ne marche pas  =( je n'arrive pas à résoudre le problème. et je  ne sais pas comment m'y prendre du coup je m'adresse à vous dans l'espoir de m'aider svp. mon programme consiste à :   a chaque fois que j'appuie sur un bouton poussoir je passe du gain proportionnel au gain pi et à prochaine fois fois que j'appuie je passe du gain pi au gain pd ainsi de suite jusqu'à ce que j'arrive au tau2 ensuite je repasse au gain proportionnel et dès que je tourne le sélecteur rotatif je change la valeur du menu en cours (gainp, pi, pid....) j'ai aussi des fonction gérantes la saturations et un choix du correcteur voici une partie de mon programme. quote   int gainp1;   int gainp2;   int gainp3;   int tau1; int tau2;   const byte egainp1 = 0; const byte egainp2 = 1; const byte egainp3 = 2; const byte etau1 = 3; const byte etau2 = 4;

salve tutti, come tesina all'esame porto una macchinetta che monta arduino comandata da un pc, il tutto è fatto, fino ieri ho eseguito le prove con le ruote della macchinetta sospese in aria, finchè scrivevo il programma in c# il tutto funzionava, le ruote giravano avanti, indietro, destra e sinistra, tutto perfetto, ieri mattina mi sono arrivati jumper maschio-femmina grazie ai quali finalmente potevo collegare la motor shield che ho fatto con due ponte h l293ne(ne ho usati 2 perchè la macchinetta per girare le ruote destra e sinistra non usa un servo motore ma un'altro motore dc, quindi con uno controllo due motori per l'accelerazione e con l'altro il motore per sterzare) e quindi potevo mettere la macchinetta terra e farla correre, mia sfortuna per terra la macchinetta non funziona...   di preciso il problema è che appena inizio farla correre funziona, però dopo qualche secondo inizia ad andare scatti. sulla macchinetta ho 3 led che accendo e spengo dal

ich möchte den kompass hmc5883l kalibrieren. es sollen soft und hard iron eliminiert werden. das ziel ist es, die rohdaten zu berechnen, dass ich ende einen plot (x,y,z) als kugelförmige wolke zu erhalte. durch internet-recherche habe ich herausgefunden, dass man den sensor um 3 achsen rotieren muss und dann alle maximalen und minimalen werte ermitteln. das steht zum beispiel hier: http://www.bot-thoughts.com/2011/04/quick-and-dirty-compass-calibration-in.html. jedoch weiß ich nicht, wie ich diese maximalen und minimalen werte ermitteln soll. ich habe den sensor schon um alle 3 achsen rotiert. für jede rotation um je eine achse erhalte ich für die anderen beiden achsen jeweils ein minimum und ein maximum. nach drei rotationen würde ich für jede achse jeweils 2 minimum und 2 maximum. in diesem datenblatt wird eine 2d-kalibrierung erklärt: http://www.jameco.com/jameco/products/prodds/2150248.pdf (ab seite 21). wie kann ich eine 3d-kalibrierung genau durchführen?
