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: |

Description: QQ2812 开发板是一套基于TMS320F2812 DSP 的学习和二次开发平台。
1、提供了二十多个实验项目，同时提供完整的原理图、代码和常用的外围接口，完全可以
作为个人、公司、高校和研究所的初学者学习和教学的工具。
2、同时，引出DSP 所有的控制信号和CPLD 的32 个IO 信号，可以作为二次开发的开发
平台。
3、采用四层板设计，充分考虑了EMC,EMI 以及散热、安装方面的因素，最大可能的引出
了所有接口，因此他也可作为功能板直接嵌入到用户的产品当中，大大缩短用户的产品开发周
期。
-QQ2812 development board is a TMS320F2812 DSP-based learning and the second development platform. 1, has provided more than 20 pilot projects, while providing a complete schematic diagram, the outer code and common interface, can be as individuals, companies, universities and the Institute of learning and teaching beginners tool. 2, at the same time, leads to all the DSP and CPLD control signals of the 32 IO signals could serve as a development platform for the secondary development. 3, using four-layer board design, full account of the EMC, EMI, as well as cooling, installation factors, led to the greatest extent possible all of the interfaces, so he can also be embedded as a function of plate directly to the user' s products, greatly reducing the user' s product development cycle.
