Designing Boards with Atmel AT89C51,AT89C52, AT89C1051, and AT89C2051 for Writing Flash at In-Circuit Test.
Recent improvements in chips and testers have made it possible for the tester to begin taking over the role tradi-tionally assigned to the PROM program-mer. Instead of having a PROM pro- g ...
设计一种基于AT89C52的语音录放系统,利用单片机、ISD2560语音录放器件、麦克风、扬声器等元器件实现硬件电路的设计,并利用C51高级语言设计ISD2560器件控制字的写入和定时中断程序。经软硬件调试,结果表明该系统录放效果良好,具有一定的工程实用价值。
