帶中文字庫的128X64是一種具有4位/8位并行、2線或3線串行多種接口方式，內部含有國標一級、二級簡體中文字庫的點陣圖形液晶顯示模塊；其顯示分辨率為128×64, 內置8192個16*16點漢字，和128個16*8點ASCII字符集.利用該模塊靈活的接口方式和簡單、方便的操作指令，可構成全中文人機交互圖形界面。可以顯示8×4行16×16點陣的漢字. 也可完成圖形顯示.低電壓低功耗是其又一顯著特點。由該模塊構成的液晶顯示方案與同類型的圖形點陣液晶顯示模塊相比，不論硬件電路結構或顯示程序都要簡潔得多，且該模塊的價格也略低于相同點陣的圖形液晶模塊。 基本特性: 低電源電壓（VDD:+3.0--+5.5V） 顯示分辨率:128×64點 內置漢字字庫，提供8192個16×16點陣漢字(簡繁體可選) 內置 128個16×8點陣字符 2MHZ時鐘頻率 顯示方式：STN、半透、正顯 驅動方式：1/32DUTY，1/5BIAS 視角方向：6點 背光方式：側部高亮白色LED，功耗僅為普通LED的1/5—1/10 通訊方式：串行、并口可選 內置DC-DC轉換電路，無需外加負壓 無需片選信號，簡化軟件設計 工作溫度: 0℃ - +55℃ ,存儲溫度: -20℃ - +60℃ 12864（帶字庫漢字顯示演示程序）

SPCE061A單片機硬件結構 從第一章中SPCE061A的結構圖可以看出SPCE061A的結構比較簡單，在芯片內部集成了ICE仿真電路接口、FLASH程序存儲器、SRAM數據存儲器、通用IO端口、定時器計數器、中斷控制、CPU時鐘、模-數轉換器AD、DAC輸出、通用異步串行輸入輸出接口、串行輸入輸出接口、低電壓監測低電壓復位等若干部分。各個部分之間存在著直接或間接的聯系，在本章中我們將詳細的介紹每個部分結構及應用。2.1 μ’nSP™的內核結構μ’nSP™的內核如0所示其結構。它由總線、算術邏輯運算單元、寄存器組、中斷系統及堆棧等部分組成，右邊文字為各部分簡要說明。算術邏輯運算單元ALUμ’nSP™的ALU在運算能力上很有特色，它不僅能做16位基本的算術邏輯運算，也能做帶移位操作的16位算術邏輯運算，同時還能做用于數字信號處理的16位×16位的乘法運算和內積運算。1． 16位算術邏輯運算不失一般性，μ’nSP™與大多數CPU類似，提供了基本的算術運算與邏輯操作指令，加、減、比較、取補、異或、或、與、測試、寫入、讀出等16位算術邏輯運算及數據傳送操作。2． 帶移位操作的16位算邏運算對圖2.1稍加留意，就會發現μ’nSP™的ALU前面串接有一個移位器SHIFTER，也就是說，操作數在經過ALU的算邏操作前可先進行移位處理，然后再經ALU完成算邏運算操作。移位包括：算術右移、邏輯左移、邏輯右移、循環左移以及循環右移。所以，μ’nSP™的指令系統里專有一組復合式的‘移位算邏操作’指令；此一條指令完成移位和算術邏輯操作兩項功能。程序設計者可利用這些復合式的指令，撰寫更精簡的程序代碼，進而增加程序代碼密集度 (Code Density)。在微控制器應用中，如何增加程序代碼密集度是非常重要的議題；提高程序代碼密集度意味著：減少程序代碼的大小，進而減少ROM或FLASH的需求，以此降低系統成本與增加執行效能。

單片機系統軟件抗干擾方法:在提高硬件系統抗干擾能力的同時，軟件抗干擾以其設計靈活、節省硬件資源、可靠性好越來越受到重視。下面以MCS-51單片機系統為例，對微機系統軟件抗干擾方法進行研究。1、軟件抗干擾方法的研究在工程實踐中，軟件抗干擾研究的內容主要是： 消除模擬輸入信號的嗓聲（如數字濾波技術）； 程序運行混亂時使程序重入正軌的方法。本文針對后者提出了幾種有效的軟件抗干擾方法。1.1 指令冗余CPU取指令過程是先取操作碼，再取操作數。當PC受干擾出現錯誤，程序便脫離正常軌道“亂飛”，當亂飛到某雙字節指令，若取指令時刻落在操作數上，誤將操作數當作操作碼，程序將出錯。若“飛”到了三字節指令，出錯機率更大。在關鍵地方人為插入一些單字節指令，或將有效單字節指令重寫稱為指令冗余。通常是在雙字節指令和三字節指令后插入兩個字節以上的NOP。這樣即使亂飛程序飛到操作數上，由于空操作指令NOP的存在，避免了后面的指令被當作操作數執行，程序自動納入正軌。此外，對系統流向起重要作用的指令如RET、RETI、LCALL、LJMP、JC等指令之前插入兩條NOP，也可將亂飛程序納入正軌，確保這些重要指令的執行。1.2 攔截技術所謂攔截，是指將亂飛的程序引向指定位置，再進行出錯處理。通常用軟件陷阱來攔截亂飛的程序。因此先要合理設計陷阱，其次要將陷阱安排在適當的位置。1.2.1 軟件陷阱的設計當亂飛程序進入非程序區，冗余指令便無法起作用。通過軟件陷阱，攔截亂飛程序，將其引向指定位置，再進行出錯處理。軟件陷阱是指用來將捕獲的亂飛程序引向復位入口地址0000H的指令。通常在EPROM中非程序區填入以下指令作為軟件陷阱：

帶中文字庫的128X64是一種具有4位/8位并行、2線或3線串行多種接口方式，內部含有國標一級、二級簡體中文字庫的點陣圖形液晶顯示模塊；其顯示分辨率為128×64, 內置8192個16*16點漢字，和128個16*8點ASCII字符集.利用該模塊靈活的接口方式和簡單、方便的操作指令，可構成全中文人機交互圖形界面。可以顯示8×4行16×16點陣的漢字. 也可完成圖形顯示.低電壓低功耗是其又一顯著特點。由該模塊構成的液晶顯示方案與同類型的圖形點陣液晶顯示模塊相比，不論硬件電路結構或顯示程序都要簡潔得多，且該模塊的價格也略低于相同點陣的圖形液晶模塊。
