DES/3DES算法的C语言实现，我对代码进行优化。只需要几十个字节的内存就可以。很适合用于单片机等下位机使用。...

YM1602的读写程序，看了就知道了，-YM1602 reading and writing process, read on to know, and

用51汇编语言设计的DTMF发生器程序 输出到PI的每次间隔是52个指令周期 主频：6M，6M/12=0.5M,每个指令周期：2uS 即每次输出到P1的时间间隔是122uS 指令周期数：52 + 9 = 61-51 assembly language using the design process DTMF generator output to the PI for each interval is 52 instruction cycle speeds : 6M, 6M/12 = for 0.5 per instruction cycle : 2uS that each output to the P1 time interval is 122uS instruction cycle : 52 9 = 61
