基于51单片机的温度?测量仪 摘要：单片?微型计算机(Sing?le Chip Mi?crocompute?r)简称单片机,又称?MCU(Micro ?Controller? Unit),是将计?算机的基本部分微型化?,使之集成在一块芯片?上的微机.片内含有C?PU、ROM、RAM?、并行I/O、串行I?/O、定时器/计数器?、中断控制、系统时钟?及系统总线等。 随着?科技的发展，单片机已不是一个陌生的名词，它的出现是近代计算机技术发展史上的一个重要里程碑，因为单片机的诞生标志着计算机正式形成了通用计算机系统和嵌入式计算机系统两大分支。单片机单芯片的微小体积和低的成本，可广泛地嵌入到如玩具、家用电器、机器人、仪器仪表、汽车电子系统、工业控制单元、办公自动化设备、金融电子系统、舰船、个人信息终端及通讯产品中，成为现代电子系统中最重要的智能化工具。—51系列，因为世?界上很多知名的IC生?产厂家都生产51兼容?的芯片。生产MCS—?51系列单片机的厂家?如美国AMD公司、A?TMEL公司、INT?EL公司、WINBO?ND公司、PHILI?PS公司、ISSI公?司、TEMIC公司及?南韩的LG公司、日本?NEC、西门子公司等?。到目前为止，MCS?—51单片机已有数百?个品种，还在不断推出?功能更强的新产品。 ?关键字： 单片机 ?
