Description: 本科毕业设计做的一个小玩意。设计的语音播报记事器系统使用AT89S52单片机为微控制器，通过对ISD4004的控制实现语音的存储与回放。PCF8563为本系统提供时间和日历等信息。当进行录音和放音时，PCF8563亦可作为计时器件使用。外接矩阵键盘和LED显示器，方便人机间的对话。本系统能够录音放音长达16分钟。压缩包内有自己的本科毕业论文，程序和原理图。有一定的参考价值。-Graduated from a design gadgets. Design Notepad voice broadcast system for the use of single-chip microcontroller AT89S52, through control of ISD4004 voice storage and playback. PCF8563-based system provides information such as time and calendar. When the recording and playback time, PCF8563 pieces can also be used as a timer. External keyboard and LED matrix displays, to facilitate dialogue between man-machine. Recording the system can playback up to 16 minutes. Compressed packet has its own undergraduate thesis, procedures and schematic diagram. A certain reference value. Platform: |

Description: 最近买了块开发板学习单片机，以下是电路原理图。不明白上面的4×4矩阵键盘(电路图最左上角）的编码原理。键盘的8条引线直接与p1.0^p1.7相连，疑惑的是即使按下任意按键也在p1口上读不到任何电平啊？
期待高手指点！-Recently bought a development board to study single-chip block, the following is the circuit schematic. Do not understand the above 4 × 4 matrix keyboard (circuit diagram most upper-left corner) encoding principle. 8-lead keyboard directly connected with the p1.0 ^ p1.7, doubts that even if the press any key I have also read p1 level no ah? Look forward to expert advice! Platform: |
