本次设计的数控直流电阻箱主要由恒定电流源部分、显示部分、键盘部分、电源部分组成。以STM32单片机为核心控制恒流源，恒流源电路由达林顿三极管、高精度运算放大器、采样电阻等组成。通过键盘输入给定值，经D/A转换器将数字信号转换为模拟信号，控制电流。采用电流反馈电路控制精度，经多次调试改进，实现了直流电阻箱的功能。本次设计的数控直流电阻箱较以往的电阻箱相比，其优点在于可操作性强、精度高、体积小、高效节能等优点。适用于作为直流负载的应用场合。(The numerical control DC resistance box designed mainly consists of constant current source part, display part, keyboard part and power supply part. The constant current source is controlled by STM32 single chip microcomputer. The constant current source circuit is composed of Darlington transistor, high precision operational amplifier and sampling resistor. Through the keyboard input a given value, the D/A converter converts the digital signal into analog signal to control the current. The control precision of the current feedback circuit is improved, and the function of the DC resistance box is realized through many debugging improvements. Compared with the conventional resistance box, the designed DC resistance box has the advantages of strong operability, high accuracy, small size, high efficiency and energy saving. It is suitable for application as DC load.)

实现SX1280的收发程序，模式可以自行设定，FLRC实测速率可以达到1Mbps(Achieve the SX1280 transceiver program, the mode can be set by itself, the measured speed of FLRC can reach 1Mbps)

此为自己兴趣，开始学C#编程做出来的一个自动备份，不过功能简单，适合初学者熟悉文件流的使用-this for their own interest, begin to learn C# programming comes an automatic backup, but a simple function, for beginners familiar with the use of document flow

说明：  改进欧拉法的matlab程序，并且其中有一个例子(Improved Euler method matlab program, and an example)

说明：  c语言是很多编程软件的基础,找最大值,也是C语言运用中的一大关键因素(C language is the basis of many programming software, to find the maximum value, is also a key factor in the use of c language)
