本資料是關(guān)于單片機(jī)電路設(shè)計(jì)的一些經(jīng)驗(yàn),希望對(duì)大家有所幫助。。。 前言 MCU發(fā)展趨勢(shì) 未來以及相當(dāng)長(zhǎng)的一段時(shí)間內(nèi),單片機(jī)應(yīng)用技術(shù)的發(fā)展趨勢(shì)為: 1、全盤CMOS化 CMOS 電路具有眾多的優(yōu)點(diǎn),如極寬的工作電壓范圍、極佳的本質(zhì)低功耗及功耗管理特征,形成了嵌入式系統(tǒng)獨(dú)特的低功耗及功耗管理應(yīng)用技術(shù)。 2、最大化的SoC設(shè)計(jì) 目前單片機(jī)已逐漸向片上系統(tǒng)發(fā)展,原有的單片機(jī)逐漸發(fā)展成通用型SoC 單片機(jī)(如C8051F 系列)或SoC 的標(biāo)準(zhǔn)IP 內(nèi)核(如DW8051_core),以及各種專用的SoC 單片機(jī)。 3、以串行方式為主的外圍擴(kuò)展 目前單片機(jī)外圍器件普遍提供了串行擴(kuò)展方式。串行擴(kuò)展具有簡(jiǎn)單、靈活、電路系統(tǒng)簡(jiǎn)單、占用I/O資源少等優(yōu)點(diǎn),是一種流行的擴(kuò)展方式。 4、8位機(jī)仍有巨大發(fā)展空間 電路常識(shí)性概念(1)-輸入、輸出阻抗 1、輸入阻抗 輸入阻抗是指一個(gè)電路輸入端的等效阻抗。在輸入端上加上一個(gè)電壓源U,測(cè)量輸入端的電流I,則輸入阻抗Rin=U/I。你可以把輸入端想象成一個(gè)電阻的兩端,這個(gè)電阻的阻值,就是輸入阻抗。 輸入阻抗跟一個(gè)普通的電抗元件沒什么兩樣,它反映了對(duì)電流阻礙作用的大小。 對(duì)于電壓驅(qū)動(dòng)的電路,輸入阻抗越大,則對(duì)電壓源的負(fù)載就越輕,因而就越容易驅(qū)動(dòng),也不會(huì)對(duì)信號(hào)源有影響;而對(duì)于電流驅(qū)動(dòng)型的電路,輸入阻抗越小,則對(duì)電流源的負(fù)載就越輕。因此,我們可以這樣認(rèn)為:如果是用電壓源來驅(qū)動(dòng)的,則輸入阻抗越大越好;如果是用電流源來驅(qū)動(dòng)的,則阻抗越小越好(注:只適合于低頻電路,在高頻電路中,還要考慮阻抗匹配問題。另外如果要獲取最大輸出功率時(shí),也要考慮阻抗匹配問題。)

利用單片機(jī)具有的智能程序控制的特點(diǎn),設(shè)計(jì)了基于STC89C52單片機(jī)的"二極管特性測(cè)試器",可對(duì)二極管一般特性進(jìn)行快速測(cè)試。通過穩(wěn)定線性電流源給二極管加載恒定電流,然后由高精度模數(shù)轉(zhuǎn)換器測(cè)試其壓降,以此為基礎(chǔ)可判斷二極管好壞、檢測(cè)二極管極性和測(cè)試二極管伏安特性等,避免了用萬用表測(cè)試只能測(cè)得極性而不知其特性這一缺點(diǎn)。可用于電子設(shè)計(jì)制作過程中對(duì)二極管進(jìn)行快速測(cè)試,以確定被測(cè)二極管是否滿足電路的設(shè)計(jì)要求。 Abstract: By making good use of the intelligent control function of the Micro Controller Unit (MCU), the diode trait tester was designed based on the STC89C52,which could be used to test the trait of a diode rapidly. By loading constant current to diode through the stable linear current source, and measuring the voltage drop of the diode by high-precision analogue-to-digital converter (ADC), it can judge whether the diode is good or not, distinguish the polarity of the diode, and test the trait that the diode, which can avoid the fault of using a multimeter can only measure the polarity but not the trait. This device can be used to test the trait of a diode quickly,and to make sure that whether a diode can be used in the electronic design or not.
