单片机编程 基于IC卡的新型供暖计费系统设计
将现行的供暖计费方式由按建筑面积计费变为按消耗的热能计费是供暖计费方式发展趋势，为了满足这一计费方式变化的需要，设计了基于IC卡的预付费式新型供暖计费系统，通过测量用户采暖系统进出口的温度和流量，计算用户消耗的热能，利用IC卡记录用户预付费的金额和当年热能的单价，根据热能消耗和当年热能的单价计算用户采暖 ...
单片机编程 基于MSP430单片机和DS18B20的数字温度计
为了在工业生产及过程控制中准确测量温度，设计了一种基于低功耗MSP430单片机的数字温度计。整个系统通过单片机MSP430F1121A控制DS18B20读取温度，采用数码管显示，温度传感器DS18B20与单片机之间通过串口进行数据传输。MSP430系列单片机具有超低功耗，且外围的整合性高，DS18B20只需一个端口即可实现数据通信，连接方便。 ...
单片机编程 An easy way to work with Exter
Internal Interrupts are used to respond to asynchronous requests from a certain part of themicrocontroller that needs to be serviced. Each peripheral in the TriCore as well as theBus Control Unit, the Debug Unit, the Peripheral Control Processor (PCP) and the CPUitself can generate an Interrupt Requ ...
