The device is manufactured using Atmel’s high density nonvolatile memory technology and is patible with the industry standard 80C51 and 80C52 instruction set and pinot. The onchip Flash allows the program memory to be reprogrammed insystem or by a conventional on volatile memory programmer. By bining a versatile 8bit CPU with Flash on a monolithic chip, the Atmel AT89C52 is a powerful microputer, which provides a highly flexible and cost effective solution to many embedded control applications. The AT89C52 provides the following standard features: 8 Kbytes of Flash, 256 bytes of RAM, 32 I/O lines, three 16bit timer/counters, a sixvector twolevel interrupt architecturea full duplex serial port, onchip oscillator, and clock circuitry. In addition, the AT89C52 is designed with static logic for operation down to zero frequency and supports two software selectable power saving modes. The Idle Mode stops the CPU while allowing the RAM, timer/counters, serial port, and interrupt system to continue functioning. The Power Down Mode saves the RAM contents but freezes the oscillator, disabling all other chip functions until the next hardware reset.

As an output port, each pin can sink eight TTL inputs. When 1s are written to port 0 pins, the pins can be used as highimpedance inputs. Port 0 can also be configured to be the multiplexed loworder address/data bus during a。 我要感謝所有的師弟師妹們,在這個團(tuán)結(jié)奮斗、積極向上、充滿愛心的集體中,我獲得了不斷進(jìn)取的動力。 我要感謝我系的各位老師,在設(shè)計過程中,我系的老師們給了我很多 種 肯 定 的建議,使我的論文得以順利的完成。他不僅在學(xué)術(shù)上給了我指導(dǎo),在生活上也給了我無盡的關(guān)懷。 本論文是在老師的悉心指導(dǎo)下才完成的。但是本產(chǎn)品相對模擬電壓表來說讀數(shù)時非常的方便,抗干擾能力強(qiáng),可擴(kuò)展性強(qiáng)等優(yōu)點。使得本直流數(shù)字電 壓表具體精度高,靈敏度強(qiáng),性能可靠,電路簡單, 設(shè)計成本低,能夠滿足一般的電壓測量。如果一樣,說明設(shè)計成功完成。接上電源運行。 5) 總調(diào)試。如果一致。 4) 檢查數(shù)據(jù)的轉(zhuǎn)換模塊程序。 3) 檢查 A/D轉(zhuǎn)換模塊程序。本設(shè)計的按鍵模塊程序是用狀態(tài)機(jī)的方法,可以在 key_state1狀態(tài)下加一個任務(wù),如顯示一個字符在液晶上。如果不能,則在相關(guān)的子程序中設(shè)計斷點,反復(fù)調(diào)試直到能夠顯示。 1) 檢查液晶顯示模塊程序。最后調(diào)試整個程序。軟件調(diào)試是一個模塊一個模塊進(jìn)行的。 2) 將 40 芯片的仿真插頭插入單片機(jī)插座進(jìn)行調(diào)試,檢查各接口是否滿足設(shè)計的要求,有正常的程序測試硬件電路的好壞。 1) 檢查所設(shè)計的硬件電路板所有的器件和引腳是否正確,尤其是電源的連接是否正確;檢查各總線是否有短路的故障。調(diào)試分了硬件和軟件調(diào)試。所以在本設(shè)計中采用 C語言編寫軟件程序。 由于現(xiàn)在單片機(jī)的發(fā)展已經(jīng)達(dá)到了很高的水平,內(nèi)部的各種資源 相當(dāng)?shù)呢S富, CPU 的處理速度非常的快。但它依賴于計算機(jī)硬件,程序可讀性和可移植性比較差。匯編語言的特點是占用內(nèi)存單元少,執(zhí)行效率高。 陜西理工學(xué)院畢業(yè)設(shè)計 第 21 頁 共 52 頁 圖 總 電路圖 陜西理工學(xué)院畢業(yè)設(shè)計 第 22 頁 共 52 頁 4. 系統(tǒng)軟件的設(shè)計 匯 編語言和 C語言的特點及選擇 本設(shè)計是硬件電路和軟件編程相結(jié)合的設(shè)計方案,選擇合適的編程語言是一個重要的環(huán)節(jié)。原理圖如下所示。 圖 1602 液晶與單片機(jī)連接 陜西理工學(xué)院畢業(yè)設(shè)計 第 20 頁 共 52 頁 按鍵控制電路設(shè)計 。 陜西理工學(xué)院畢業(yè)設(shè)計 第 19 頁 共 52 頁
