這位同好: 請參考"教育訓練"中之 W201 課程用程式, 其中的 LAB#6 就是 PIC16F877A PWM 的應用. 祝您好運!

嗨! Julian47:
您可以光臨下述網站, 那裡有一脫拉庫的數學函式:

Hi! Dear marcowing:

1.Assembly: 學習 PICmicro 的硬體架構
2.C Language: 快速的完成一項Project.

所以用組合語言或 C 語言, 端視您的用途, 但是 Microchip 的 MCU, 其 program memory 也愈來愈大, 故您可以用 8KBytes 作為一個分別:
1.Program size < 8KB: Use assembly
2.Program size > 8KB: Use C language

Hi! Dear Nephi:

1.可以的.
2.若是美國樣品倉有樣品, 約兩週內就可以收到樣品了.

Microchip MPLAB 可以預載 configure Bits, 你所列的方式只適用於組合語言 (Assembly) 之用. 若你是使用 MPLAB C18, 也想預載 configure Bits, 請參考下述方式. 您也可以參考右方 "教材及講義" 中的 WAP002, 以獲取完整之用法.

以 PIC18F452 為例:
建立一個檔案 - P18config.c, 將虛線內之內容複製進去, 存檔後, 將此檔加入專案中, 重新編譯即可. 祝您好運. (此內容只是範例, 請參考 PIC18F452 的 Program Spec 修改其內容.)

Hi! Zarya30:
想要C18能夠正常的編譯(Compile), 有幾點必須確定的:
1. C18若是Demo版, 須在有效期間(60天)內
2. C18的安裝目錄須記住(常會用到)
3. 請將每一個練習題目錄都放於根目錄之下,ex. C:\ex1
4. Project目錄中,不允許含有Unicode(ex.中文字)
5. 若是Workshop的練習題之中已有.mcp與.mcw, 請務必以"OPEN"的方式開啟Project
6. 新建的Project請務必將"Project"->"Build Option" -> "Project"中的"Include","Library"與"Linker"均確實設定:
a. Include - C:\MCC18\H
b. Library - C:\MCC18\LIB
c. Linker - C:\MCC18\LKR

祝您成功的使用 MPLAB C18

請問您用的是 Int_RC(4MHz) or Int_OSC(31KHz-8MHz) switching by OSCCON. 請說明之. 謝謝!

Hi! You can refer to any one PIC18 data sheet, you'll see some statement to access with internal EEprom, make
sure your code are wrote closely (no other gabbage between you code), I suggest you use in-line assembly code to make the code as a function in your project.
If you still have problem on it, please contact with me.
