电子负载

说明：  用PSIM实现基于扰动观测法的MPPT最大功率点追踪(Use psim to achieve the goal of mppt)

通过IO口控制两路24V电压输出，一路24V转两路24V(Two 24V voltage outputs are controlled by IO port, one 24V is converted to two 24V.)

AD5754 驱动程序 ADI 官方驱动 收发函数都有(The AD5754 driver ADI official drive transceiver function is available)

说明：  基于SIMULINK的dcdc开关电源仿真模型(dcdc converter simulation based on simulink)

4G模块EC20开发资料，硬件设计手册，AT指令，原理图和PCB图封装，完整开发资料。(Development Data of 4G Module EC20 and Hardware Design Manual)

一个高性能麦克风电路设计，电路具有高保真润色好等等特点(A High Performance Microphone Circuit Design)

说明：  基于51/52单片机 1，探测环境温度，以LCD1602 做显示单元 2，可设置上限/下限数值，从而做到警报的提醒及应急设施的启动 3，超过设置限值时，会启动 LED 、蜂鸣器以及电机（仿真时使用）应用可使用其他代替(Based on 51 / 52 single chip microcomputer 1. Detect the ambient temperature with LCD1602 as the display unit 2. The upper / lower limit value can be set to remind the alarm and start the emergency facilities 3. When the setting limit is exceeded, the LED, buzzer and motor (used in simulation) application will be started, and other alternatives can be used)

说明：  文件中包含stm32开发板所配套的开关使用说明的程序例程，重在讲解开关是如何被使用的，在kEIL5软件上怎么编写的。(The document contains the program routine of the switch instructions matched by STM32 development board, focusing on how the switch is used and how to write on kEIL5 software.)
