4x4矩阵键盘电子琴把“单片机系统”区域中的P1.0 端口用导线连接到“音频放大模块”区域中的SPK IN 端口上;
(2. 把“单片机系统“区域中的P3.0-P3.7 端口用8 芯排线连接到“4X4 行列式键盘”区域中的C1-音乐产生的方法;
一首音乐是许多不同的音阶组成的,而每个音阶对应着不同的频率,这样我们就可以利用不同的频率
的组合,即可构成我们所想要的音乐了,当然对于单片机来产生不同的频率非常方便,我们可以利用单片
机的定时/计数器T0 来产生这样方波频率信号,因此,我们只要把一首歌曲的音阶对应频率关系弄正确即
可。现在以单片机12MHZ 晶振为例,例出高中低音符与单片机计数T0 相关的计数值如下表所示-err

红外通信是利用950nm近红外波段的红外线作为传递信息的媒体,即通信信道。发送端采用脉时调制(PPM)方式,将二进制数字信号调制成某一频率的脉冲序列,并驱动红外发射管以光脉冲的形式发送出去;接收端将接收到的光脉转换成电信号,再经过放大、滤波等处理后送给解调电路进行解调,还原为二进制数字信号后输出。-Infrared communication is the use of near infrared 950nm infra-red as the transmission of information media, namely communication channel. The sending end when the use of pulse modulation (PPM) approach will be a binary digital signal into a frequency modulation of the pulse sequence, and driver fired infrared tube to the form of light pulses sent receiver will receive the pulse of light conversion to electrical signals , and then, after amplification, filtering and other treatment to the demodulation circuit after demodulation, reduced to a binary digital signal after the output.

单片机RS232/RS485串行发送实验(双机通讯)。
实验步骤:
(1),准备两台598K实验机,确定1号机为发送,2号机为接收;
(2),当作RS232接口实验时,1号机和2号机的P3.0和P3.1交叉相连,且两机共地;
(3),当作RS485接口实验时,1号机和2号机的A、B作对应连接,同时1,2号机的R/TEN接P1.0, P3.0接R0, P3.1接DI。
(4),先运行2号机,键入[27]-->[EV]使2号机处于接收状态P。,后运行1号机[26]-->[EV]使1号机处于发送状态,P。会闪烁,在1号机键盘上按动数字键,在2号机的数码管上应显示对应的数字键值。-Send Singlechip RS232/RS485 serial experiment (two-plane communications). Experimental steps: (1), prepare two sets of experiments 598K machine, determined on the 1st machine to send, on the 2nd machine to receive (2), as a RS232 interface experiment, on the 1st and the 2nd machine and P3.0 P3.1 cross-linked, and the two planes were to (3), as a RS485 interface experiment, on the 1st and the 2nd machine A, B for the corresponding connection, while 1,2 No. of R/TEN then P1 .0, P3.0 access R0, P3.1 then DI. (4), first run on the 2nd machine, type [27]
