הבדל בין בקרים מאותו הדגם...כן...כן...

[rafi533]

ישבתי לי וחיפשתי לרכוש את השבב עצמו של בקר מסוג PIC16F887 ....
ולהפתעתי גיליתי שיש איזה 6 סוגים או יותר באתר של מיקרוצ'יפ... מישהו יודע לומר לי מה ההבדל בין כולם?

ודבר נוסף..מישהו יודע להגיד לי איזה פינים אני צריך לחבר כדי לצרוב אותם עם PICKIT2?


תתמקדו הייטב ושימו לב לפרטים שבצבעים...שם ההבדל..... PIC16F887 ואז יש כמה אותיות שלא ברור לי מה המשמעות שלהן ומה מהם אני רוצה להזמין...

תודה...

מצאתי תשובה חלקית....
עמוד 325 בחוברת עצמה (לא במספור של ה PDF)...
https://ww1.microchip.com/downloads/en/ ... 41291F.pdf

עדיין אני לא יודע איזה מהם אני רוצה וצריך...לשימוש רגיל ופשוט...

[Alex]

מה זה שימוש רגיל ופשוט?

אם אתה משתמש במטריצה או בלוח הלחמה עם חורים, אז אתה צריך אריזת DIP. טמפרטורה כנראה לא אמורה לעניין אותך אלא אם אתה בונה טיל.

[rafi533]

איזה מהם?

תודה רבה! מה הם שאר הסוגים? בא נפרט פה שיהיה את המידע בפורום..

[Alex]

אלה אריזות שונות של השבבים (הדרך בה הרגליים שלהם חשופים להלחמה), הנה ריכוז ב-Wiki:
