89C51单片机串口打印00H-99H，定时器1产生波特率，波特率值为9600(C51 89 C51 serial print 00 H-99 H, the timer 1 produce baud rate, baud rate value for 9600 serial print 00 H-99 H )

RN8209计量芯片通讯读写程序，已经使用于单相电量表中(RN8209)

八个发光二极管L1－L8分别接在单片机的P1.0－P1.7接口上，输出“0”时，发光二极管亮，开始时P1.0→P1.1→P1.2→P1.3→┅→P1.7→P1.6→┅→P1.0亮，重复循环。 (Eight light-emitting diodes L1-L8, respectively, then in the P1.0-P1.7 microcontroller interface, the output " 0" when the bright light-emitting diode, the beginning of P1.0 → P1.1 → P1.2 → P1. 3 → ┅ → P1.7 → P1.6 → ┅ → P1.0 Liang, repeat the cycle.)

此程序可实现长度为8位，周期为255的m序列，此序列可当做伪随机信号发生器，模拟信道噪声。(This procedure can achieve the length of 8 bits, the m sequence of 255 cycles, the sequence can be used as a pseudorandom signal generator, analog channel noise.)
