1、对于刚接触义隆单片机的朋友，这个文档或许对你有帮助。尤其是使用 C 语言的朋友， 这个程序包含了位定义、定时器、中断等。 C 语言的编译器可以去义隆单片机的官网下载，.tw，编译软件为 eUIDE。 本程序用以取代原有产品的 RS 触发器，以及 RS 输出与另外一个变量进行逻辑与运算 的功能，如果逻辑运算结果为 1，则两个 IO 口都要输出高电平，并保持 30s 和 45s。否则输 出低电平。下面是代码部分。 #include“EM78P153S.H“ #define DISI()_asmdisi #define WDTC()_asmwdtc #define NOP()_asmnop #def
