The PCF8578 is a low power CMOS1 LCD row and column driver, designed to drive dotmatrix graphic displays at multiplex rates of 1:8, 1:16, 1:24 or 1:32. The device has40 outputs, of which 24 are programmable and configurable for the following ratios ofrows/columns: 32¤8, 24¤16, 16¤24 or 8¤32. The PCF8578 can function as a stand-alone LCDcontroller and driver for use in small systems. For larger systems it can be used inconjunction with up to 32 PCF8579s for which it has been optimized. Together these twodevices form a general purpose LCD dot matrix driver chip set, capable of driving displaysof up to 40960 dots. The PCF8578 is compatible with most microcontrollers andcommunicates via a two-line bidirectional bus (I2C-bus). Communication overhead isminimized by a display RAM with auto-incremented addressing and display bankswitching.

CAN，全稱為“Controller Area Network”，即控制器局域網(wǎng)，是國(guó)際上應(yīng)用最廣泛的現(xiàn)場(chǎng)總線之一。最初，CAN被設(shè)計(jì)作為汽車環(huán)境中的微控制器通訊，在車載各電子控制裝置ECU之間交換信息，形成汽車電子控制網(wǎng)絡(luò)。比如：發(fā)動(dòng)機(jī)管理系統(tǒng)、變速箱控制器、儀表裝備、電子主干系統(tǒng)中，均嵌入CAN控制裝置。一個(gè)由CAN 總線構(gòu)成的單一網(wǎng)絡(luò)中，理論上可以掛接無(wú)數(shù)個(gè)節(jié)點(diǎn)。實(shí)際應(yīng)用中，節(jié)點(diǎn)數(shù)目受網(wǎng)絡(luò)硬件的電氣特性所限制。例如，當(dāng)使用Philips P82C250作為CAN收發(fā)器時(shí)，同一網(wǎng)絡(luò)中允許掛接110個(gè)節(jié)點(diǎn)。CAN 可提供高達(dá)1Mbit/s的數(shù)據(jù)傳輸速率，這使實(shí)時(shí)控制變得非常容易。另外，硬件的錯(cuò)誤檢定特性也增強(qiáng)了CAN的抗電磁干擾能力。
