紅外遙控器已經(jīng)廣泛使用在彩電、音響系統(tǒng)和各種家用電器中。遙控器的控制距離一般可到6~8米,使用非常方便。因紅外遙控方式用量大,所以其紅外發(fā)射、接收電路均有完整的配套器件,這些器件不僅售價(jià)低而且可靠,電路
意法半導(dǎo)體(STM)推出一款先進(jìn)的多點(diǎn)觸感“電阻式”觸摸屏控制器芯片,以優(yōu)化支持這項(xiàng)先進(jìn)功能的電子元器件的材料成本。STM32TS60是意法半導(dǎo)體最新STMTouch系列產(chǎn)品的首款產(chǎn)品,此系列為客戶提供應(yīng)用廣泛的解決方案
越來越多企業(yè)開始使用變速驅(qū)動(dòng)發(fā)動(dòng)機(jī)來減少能源的消耗。這需要通過從微分(PID)控制器轉(zhuǎn)向基于模糊邏輯算法的系統(tǒng)來簡化設(shè)計(jì),縮短開發(fā)時(shí)間,并消除復(fù)雜的數(shù)學(xué)公式。 但是,這對發(fā)動(dòng)機(jī)提出了新的挑戰(zhàn)。當(dāng)使用傳統(tǒng)
