在集成电路中,通常采用T型解码网络实现数字量往模拟的转换,再利用运算放大器完成模拟电流变为模拟电压的转换。所以,要把一个数字量变为模拟电压,实际上需要两个环节,先把数字量变为模拟电流,这是由D/A转换器完成的;再将模拟电流变成模拟电压,这是由运算放大器完成的。有时D/A转换器芯片只包含前一个环节,有些D/A转换器则包含两个环节,用前一种芯片时,需要外接运算放大器才能得到模拟电压。-In integrated circuits, the usual T-decode digital networks to analog conversion, and then complete the simulation of the use of op-amp current into the analog voltage conversion. Therefore, it is necessary to become a digital simulation of voltage, in fact, need two links, first into a digital simulation of currents, this is determined by D/A converters completed then simulate current into the analog voltage, this is determined by computing completed amplifier. Sometimes D/A converter chip contains only a part before, some D/A converter includes two aspects, before a chip, the need for external op-amp voltage can be simulated.

ST套件产生汽车防盗器报警声,本实例的目的是让大家学会用单片机产生声音的方法,学会计算程序所用时间 本实例的功能是能用16F84产生汽车防盗器的报警声,频率分两个0.1s第一个
0.1S频率从1.8K-3.5K匀速增加第二个0.1S频率从3.5K-1.8K匀速减少,
程序复位后,按S2喇叭叫两声,按S3喇叭叫15秒,中途可按S5停止.
PIC单片机
烧写时应注意:配置位已经在程序中写明,加载HEX文件时会自动加载,烧写时不用再手动设置配置位。
实验时请注意套件跳线选择;-pic
