קורס אמבדד – 001

מטרות :

1 .פיתוח מערכות אלקטרוניות משובצות מחשב , תרגול ושליטה בשפת C אמבדד בסביבות שונות .

2. העשרה והכרה של רכיבים אלקטורנים

3.העשרה והכרה של מיקרומעבדים שונים

4. העשרת השפה האנגלית בתחום האמבדד .

5. יכולת ניתוח מוצרים קיימים , בלוק דיאגרם של מוצר והערכת עלות וזמן פיתוח אב טיפוס ראשוני .

6.פיתוח מערכת שלמה מבוססת אמבדד , אמבדד RF

בקורס נעסוק במספר מעבדים

תרגיל :

1.בשפת C לולאה for עולה ויודדת

2.בשפת C לולאת WHILE

סרבו :

תכנות רמזור מעבר חציה למכוניות – ושער משמרות זהב

1.שלב ראשון נבנה רמזור למכוניות ושער להוכלי רגל – תוכנית פשוטה

לתכונית יש מספר בגים ונשפר אותה בשלב השני .

התחלת התוכנית – מצב קמזור למכוניות ירוק – לילדים שער סגור

2.לחיצה על כפתור ירוק – פתיחה

3.לחיצה על כפץור ירק – סגירה
