選擇 MPLAB C18 C Compiler(mcc18.exe)
但是build all 會有問題
我不了解哪裡有問題??
感謝版主的慈悲!!

我遇到一個很奇怪的問題
我的mcu是12f675
電路設計是沒有石英晶體的,用的是內部震盪
可是呢我燒錄時~~設定由內部震盪
程式動作就壞怪怪的!!

我就改成不內部震盪,也沒外部震盪.
程式動作就正常了!!

我有看過有關12f675內部震盪的資料
有LP XT HS RC EC INTOSC
INTOSC是內部震盪的設定??
他是在CONFIG裡邊設定的嗎??
為什麼12F675的DATA MEMORY沒有CONFIG的暫存器??

請問各位大大有遇到這樣的問題過嗎??
我很疑惑??

事情是這樣的
公司內有兩台電腦分別假設為A跟B

軟體是MPLAB IDE v7.50免費的
A電腦跟B電腦都是用這套軟體

第一個問題

奇怪的事情發生了!!
同樣的code(燒錄設定也都一樣)
在A電腦燒錄後MCU動作是正常的
在B電腦燒錄後動作就異常了!!

請問各位先進有遇過類這樣的問題嗎??
我是覺得是232傳輸的問題!!
但是MPLAB IDE v7.50這套軟體我不知道在哪裡可以設定232傳輸了速率-------------

**************************************

第2個問題是

吾人在B電腦把這套軟體(MPLAB IDE v7.50)刪除,然後從灌..
發現一個令人困惑的問題...
在Project --> project wizard 裡的

第二步 設定Microchip MPASM Tollsuite 的路徑
怎麼會記憶上次的路徑

例如:上次是灌在D槽 這次灌在C槽
這次要將路徑由
D:\Program Files\Microchip\MPASM Suite\MPASMWIN.exe改為
C:\Program Files\Microchip\MPASM Suite\MPASMWIN.exe時就會有問題!!

各位先進....
請問哪裡可以到有關
MPLAB模擬....有關Debugger功能裡頭....
可以設定I/O腳的...資料

請問各位先進~~~~pic16f72
有可以判斷負號的旗標ㄇ???
請先進教教可以ㄇ!!感恩拉

請問組合語言的除法,我想用的方法是右移的方法
因為我覺得用迴圈浪費時間
假設是39除3以組合語言右移是除2
除三的話我該怎麼做ㄋ???
25/5也是一個問題???
請各位先進教教我吧???
我想了一個晚上,還是沒想通,

有什麼辦法讓單晶片輸出穩定??

其實你可以用中斷~~~有資料近TXREG就跳中斷!!
沒資料就在主程式等待
