| + | Αρχικός στόχος μας ήταν η δημιουργία μιας εφαρμογής στην οποία θα μπορούσαμε να εξοικειωθούμε με την χρήση της θύρας ethernet καθώς με διάφορα περιφερειακά με τα οποία θα μπορούσαμε να είχαμε αλληλεπίδραση με το χρήστη. | ||
| + | |||
| + | Η εφαρμογή η οποία δημιουργήσαμε αποστέλει ενα HTTP request στην ιστοσελίδα openweathermap.org με την δυνατότητα ο χρήστης να επιλέξει την πόλη την οποία επιθυμεί. Στη συνέχεια διαχωρίζουμε τα δεδομένα τα οποία δεχτήκαμε και εκτυπώνουμε αυτά τα οποία έχουμε προεπιλέξει. | ||
| + | |||
| + | Για την εφαρμογή χρησιμοποιήσαμε την βιβλιοθήκη **mbed-http** | ||
