在超聲技術(shù)日益發(fā)展的今天，一個(gè)高質(zhì)量的超聲信號(hào)源成為各種超聲產(chǎn)品的主動(dòng)力。傳統(tǒng)模擬超聲信號(hào)源的智能化控制尚不完善,只能直接產(chǎn)生適當(dāng)頻率的電信號(hào)，用以驅(qū)動(dòng)特定的超聲波換能器。這對(duì)于信號(hào)源的合理利用是一個(gè)較大的弊端。本文介紹了一種采用單片機(jī)與復(fù)雜可編程邏輯器件(CPLD)相結(jié)合的方法設(shè)計(jì)的新型任意波形發(fā)生器(AWG)。其中波形合成采用了直接數(shù)字合成(DDS)技術(shù)。本系統(tǒng)能輸出頻率和幅度可調(diào)的多種標(biāo)準(zhǔn)函數(shù)波以及任意波形。信號(hào)頻率范圍覆蓋超低頻和高頻，同時(shí)極大地提高了頻率的分辨率和準(zhǔn)確度，因此可以用它代替常用的模擬超聲信號(hào)源。本系統(tǒng)采用單片機(jī)（AT89S52）對(duì)整機(jī)的輸入、輸出過(guò)程和波形數(shù)據(jù)采集進(jìn)行控制。高速的CPLD（EPM7128S）將波形數(shù)據(jù)從存儲(chǔ)器（AT28C256）中讀出并送給波形生成DAC（AD7524）進(jìn)行轉(zhuǎn)換，形成所要的波形。并通過(guò)改變幅度控制DAC（DAC0832）的輸入值來(lái)調(diào)節(jié)輸出波形的峰值。用戶通過(guò)面板上的矩陣鍵盤(pán)和1602液晶模塊進(jìn)行人機(jī)交互。串行E2PROM（AT24C02）實(shí)現(xiàn)了波形數(shù)據(jù)掉電保存功能。任意波形數(shù)據(jù)既可由輸入的模擬信號(hào)經(jīng)A/D轉(zhuǎn)換后獲得，也可采用具備RS-232接口的手寫(xiě)板直接輸入。

在電子工程設(shè)計(jì)與測(cè)試中，常常需要一些復(fù)雜的、具有特殊要求的信號(hào)，要求其波形可任意產(chǎn)生，頻率方便可調(diào)。通常的信號(hào)產(chǎn)生器難以滿足要求，市場(chǎng)上出售的任意信號(hào)產(chǎn)生器價(jià)格昂貴。結(jié)合實(shí)際需要，我們?cè)O(shè)計(jì)了一種任意波形發(fā)生器。電路設(shè)計(jì)中充分利用MATLAB的仿真功能，將希望得到的波形信號(hào)在MATLAB中完成信號(hào)的產(chǎn)生、抽樣和模數(shù)轉(zhuǎn)換，并將得到的數(shù)字波形數(shù)據(jù)存放在數(shù)據(jù)存儲(chǔ)器中，通過(guò)單片機(jī)和CPLD控制，將波形數(shù)據(jù)讀出，送入后向通道進(jìn)行A/D轉(zhuǎn)換和放大處理后得到所需的模擬信號(hào)波形。利用上述方法設(shè)計(jì)的任意波形發(fā)生器，信號(hào)產(chǎn)生靈活方便、功能擴(kuò)展靈活、信號(hào)參數(shù)可調(diào)，實(shí)現(xiàn)了硬件電路的軟件化設(shè)計(jì)。具有電路結(jié)構(gòu)簡(jiǎn)單、實(shí)用性強(qiáng)、成本低廉等優(yōu)點(diǎn)。

看門狗定時(shí)器的工作原理:WDT 工作原理使能時(shí)，WDT 將遞增，直到溢出，或稱“超時(shí)”。除非處于休眠或空閑模式，WDT 超時(shí)會(huì)強(qiáng)制器件復(fù)位。為避免WDT 超時(shí)復(fù)位，用戶必須定期用PWRSAV 或CLRWDT 指令將看門狗定時(shí)器清零。如果WDT 在休眠或空閑模式下超時(shí)，器件將喚醒并從PWRSAV 指令執(zhí)行處繼續(xù)執(zhí)行代碼。在上述兩種情況下，WDTO 位（RCON<4>）都會(huì)置1，表示該器件復(fù)位或喚醒事件是由于WDT超時(shí)引起的。如果WDT 將CPU 從休眠或空閑模式喚醒，“休眠”狀態(tài)位（RCON<3>）或“空閑”狀態(tài)位（RCON<2>）也會(huì)置1，表示器件之前處于省電模式。9.2.1 使能和禁止WDT通過(guò)FWDTEN（CW1<7>）配置位可將WDT 使能或禁止。FWDTEN 配置位置1 時(shí)，使能WDT。這是已擦除器件的默認(rèn)值。關(guān)于閃存配置字寄存器的更多詳細(xì)信息，請(qǐng)參見(jiàn)器件數(shù)據(jù)手冊(cè)。

MCP定時(shí)器產(chǎn)生中心對(duì)稱PWM輸出:PWM波是一種脈寬可調(diào)的脈沖波，用于交、直流電機(jī)的電壓控制。PWM一共有兩種調(diào)整方法，一是定頻調(diào)寬、另一種是定寬調(diào)頻。其中定頻調(diào)寬是種最常見(jiàn)的脈寬調(diào)制方式，它使脈沖波的頻率保持不變，只調(diào)整脈沖寬度。同時(shí)定頻調(diào)寬的PWM波形也分為兩種，一種是單邊的PWM，另一種是中心對(duì)稱的雙邊PWM。中心對(duì)稱的PWM主要應(yīng)用在需要對(duì)稱PWM波形的場(chǎng)合，如半橋、全橋的雙極性驅(qū)動(dòng)等。中心對(duì)稱的PWM的生成原理如圖1-2所示：定時(shí)計(jì)數(shù)器工作在連續(xù)增減計(jì)數(shù)方式，在計(jì)數(shù)初值設(shè)置為0且比較值小于周期值的條件下，當(dāng)增計(jì)數(shù)過(guò)程中計(jì)數(shù)值和比較值匹配時(shí)置位輸出，而在周期匹配時(shí)會(huì)改計(jì)數(shù)方向?yàn)闇p計(jì)數(shù)，當(dāng)減計(jì)數(shù)過(guò)程中計(jì)數(shù)值和比較值匹配時(shí)復(fù)位輸出，當(dāng)減計(jì)數(shù)到零時(shí)會(huì)改計(jì)數(shù)方向?yàn)樵鲇?jì)數(shù)，開(kāi)始下一個(gè)循環(huán)。因此中心對(duì)稱的PWM的周期為設(shè)定周期的二倍，占空比為：%100))((×−TPRNTPR（N為比較匹配數(shù)據(jù)，TPR為周期寄存器的值）。比較值的改變會(huì)影響PWM的兩邊的波形，并且兩邊相對(duì)高電平的中心對(duì)稱，這便是中心對(duì)稱雙邊PWM波形的特點(diǎn)。如果比較值為零，那么PWM將一直輸出高電平；如比較值大于等于周期值，則PWM會(huì)一直輸出低電平，占空比為0。
