  • (1)測試外部數據RAM: 根據我們定義的邏輯

    (1)測試外部數據RAM: 根據我們定義的邏輯,外部RAM在數據空間中定義在0x8000-0xFFFF,共32k字,占據RAM中的低32K存儲空間。提供2種測試方法,采用一種方式即可。 硬件仿真模式下,將目標板上電。 第一種方法:采用用程序測試實驗 程序所在目錄ex1_RAMTest。 該程序執行的功能是對外部數據RAM區0x8000-0xFFFF,從0x8000開始寫并且讀數據0x5555 。如果正常則寫讀下一個地址,直到 。如果正常則所有的地址操作完畢后,核心板的指示燈會變亮。否則,如果寫入數據后,讀出的不正確,則指示燈會不斷閃爍。 在CCS2000中的操作如下: 1. Progect->Open,打開該目錄中的工程文件。 2. Progect->Rebuild All,編譯鏈接 3. File->Program 4. Debug->Go Main 5. Debug->RUN(快捷鍵F5) 如果正常可以看到燈在熄滅約4秒后變亮。(說明:對整個數據RAM區的操作時間其實很短,為便于觀察,本程序中加入了延時)。 打開View->Memory ,然后填入地址0x8000,然后在PAGE欄選擇DATA。點擊確定,即可顯示0x8000地址開始的數據,用戶會發現從這個地址開始往后的數據均為剛被寫入的0x5555。

    The W78E58B is an 8-bit microcontroller which has an in-system programmable Flash EPROM for firmware updating. The instruction set of the W78E58B is fully compatible with the standard 8052. The W78E58B contains a 32K bytes of main ROM and a 4K bytes of auxiliary ROM which allows the contents of the 32KB main ROM to be updated by the loader program located at the 4KB auxiliary ROM 512 bytes of on-chip RAM four 8-bit bi-directional and bit-addressable I/O ports an additional 4- bit port P4 three 16-bit timer/counters a serial port. These peripherals are supported by a eight sources two-level interrupt capability. To facilitate programming and verification, the ROM inside the W78E58B allows the program memory to be programmed and read electronically. Once the code is confirmed, the user can protect the code for security

  • 2007年全國大學生電子設計大賽

    2007年全國大學生電子設計大賽,A題音頻信號分析儀的全部源程序。 單片機為c8051f120,系統時鐘倍頻至96MHZ。 main.c是一個包含五級菜單的主函數。 FFT.C是進行fft變換,將時域信號變換成頻域信號。 flash.c是讀寫片外flash存儲器的程序,可以將分析結果保存,以備調用. z7290.c是周立功7290鍵盤芯片的驅動程序. FFT_xgjis.c是對變換后的頻譜進行分析和運算. FFT_CodeTable.c是一個正弦表,在FFT的時候調用. LCD320240.c是320*240的液晶驅動程序,液晶的控制器是SED1335. 所有的.h文件提供了子函數的定義. 本程序用KEIL3 802版本編譯通過,將所有的.C文件添加到工程中,并編譯main.c 注意兩點:1.器件選擇c8051f120. 2.在target中將時鐘設為96M.同時必須將Memory Model 改成large--XDATA.默認的是small. 因為本設計占用的資源是非常大的. Program Size: data=81.3 xdata=6811 code=43056
