描述

底板主要由A/D電路、TFT彩色屏接口、網(wǎng)絡(luò)接口電路、觸摸屏接口電路組成，各部分的電路如下面所述。

A/D芯片與CPU的接口

A/D芯片采用AD7864，AD7864是一種高速、低功耗、可以4通道同時(shí)采樣的A/D轉(zhuǎn)換器。它的主要特性有：高速12位A/D轉(zhuǎn)換器；同時(shí)采樣4個(gè)輸入通道，并具有4個(gè)采樣、保持放大器；0.35μs采樣保持獲取時(shí)間，每一個(gè)通道轉(zhuǎn)換時(shí)間1.65μs；可以通過軟件或者硬件的方法選取用于采樣的通道；單電源供電(+5V)；多個(gè)轉(zhuǎn)換電壓范圍；具有高速并行接口，可以與處理器直接連接；低功耗，每通道功耗90mW；對于每一個(gè)模擬輸入通道均有過壓保護(hù)電路。AD78644通道同時(shí)工作時(shí)，最大采樣率可以高達(dá)130kHz。用了2片AD7864，可以同時(shí)采樣8路信號，同時(shí)監(jiān)測8個(gè)通道。

通常的機(jī)械的轉(zhuǎn)速的范圍在100～30000轉(zhuǎn)/分，即最高頻率為500Hz，根據(jù)振動(dòng)分析儀的采樣需要，每個(gè)周期采128個(gè)點(diǎn)計(jì)算，采樣頻率不超過64kHz，這樣的采樣頻率與S3C2410的CPU核心頻率200MHz、外部數(shù)據(jù)總線頻率的100MHz相比還是很低的。

因此采用AD7864的A/D轉(zhuǎn)換結(jié)束信號BUSY的下降沿中斷CPU，然后由S3C2410直接讀取A/D轉(zhuǎn)換后的數(shù)據(jù)到內(nèi)存中去。沒有采用外部RAM緩存A/D轉(zhuǎn)換后的數(shù)據(jù)或用FIFO來對數(shù)據(jù)進(jìn)行緩存，然后再由CPU讀取緩存里數(shù)據(jù)的方法。電路的實(shí)際測試結(jié)果是采樣頻率小于100kHz時(shí)，完全可以正確無誤的讀取到采樣后的數(shù)據(jù)，大大的簡化了A/D采樣部分的電路設(shè)計(jì)及節(jié)省了電路成本。
