说明：  基于51单片机，实现矩阵计算器，可以进行仿真。(Based on 51 single chip computer, matrix calculator can be realized and simulated.)

silabs的芯片si1010的发射频谱等文件，我看本站只有si1000的却没有si1010的，故此奉献(emission spectrum and other documents silabs chip si1010, I see only the site but no si1010 si1000, and therefore dedication)

这是一个用keil-51编写的C51程序，里面含有温度控制的PID核心算法，这为温度的精密控制提供了保证，同时有液晶12864的驱动，而且有PCB电路图，供大家学习和参考。(This is a written with keil-51 C51 program, which contains the core PID temperature control algorithm, which is the precise temperature control can be ensured, while an LCD 12864 driver, but also PCB circuit, for your study and reference.)

本系统是一套机载数据采集模块和远程终端。数据采集模块可以独立采集对象（小型飞机或航模）的姿态、高度等参数，并通过无线方式发送到远程终端；远程终端具有数据的实时显示、报警功能，并可记录数据完成回放。 在本设计方案中，使用MPU6050模块测量小型飞机的姿态角、航向角，使用气压测量模块与超声波测量模块来确定飞机的高度，使用WIFI模块进行数据传输，使用北斗卫星定位模块进行小型飞机的位置确定，在远程终端PC机上对数据进行解算，并采用MATLAB GUI对采集到的数据进行图形化的显示。(This system is a set of airborne data acquisition module and remote terminal. The data acquisition module can independently collect the attitude and altitude parameters of the object (small aircraft or model) and send them to the remote terminal by wireless mode. The remote terminal has the functions of real-time data display and alarm, and can record and play back the data. In this design, MPU6050 module is used to measure the attitude angle and heading angle of small aircraft, air pressure measurement module and ultrasonic measurement module are used to determine the height of the aircraft, WIFI module is used to transmit data, Beidou satellite positioning module is used to determine the position of small aircraft, and data is obtained on remote terminal PC. The calculation is carried out, and the collected data is displayed graphically by using MATLAB GUI.)

this is a code and used for keypad scanning it can used by anyone very simple one
