???這是獨角戲嗎?怎麼一個人自問自答...真奇怪

引言:
MP-USB Wizard 2.0是一個圖形用戶介面Windows應用軟體，能夠指導工程師建立描述表（Descriptor Table）。該軟體預計自12月起可在Microchip網站免費下載。

我找不到MP-USB Wizard 2.0的下載點耶

PIC16C57C 保護後，只有 ID number 可以讀出來其它的值都為 "0"

就算是找到 PIC16C73A 大概也沒用，你沒有程式就無法燒碼進去，而且PIC16C73A燒錄保護後程式也無法被讀出來拷貝。

只要不超過20MHz,當然可以。要用HS震盪模式。

請問xtal是否一定要用20MHz,若用19.6608MHz取代可以嗎?Thanks.

以前好像也有人問過同樣的問題,
真糟糕(有一段時間沒用了),
先至 Configure->Select Device底下
Device指定你要燒錄的IC就可以了
