CS5460芯片在MSP430单片机中的应用(Application of CS5460 chip in MSP430 single chip microcomputer)

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.)

说明：  电荷泵的详细说明，帮助理解及计算电荷泵的电压翻转器(Detailed description of charge pump)

电路的连接图，程序都有注释，仿真平台protues，适合初学的人(The connection diagram of the circuit, the program has the annotation, the simulation platform Protues, suitable for the first student)

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：  DAC7811驱动，好用的，测试电路是芯片手册12页给出的电路(The driver of DAC7811,I tested it and it could work well.)

说明：  基于单片机的电阻、电容、电感测试仪 可测电容，电感，电阻等元器件的值(Resistance, Capacitance and Inductance Tester Based on Single Chip Microcomputer)

EM78P451 SPI官方使用程序，内涵主机模式、从机模式已经.INC头文件。(EM78P451 SPI The official use program, the connotations of the host mode, the slave mode has.INC header file.)

说明：  ATSHA204A加密芯片详细使用方法！ 保护您的程序不被抄袭。(ATSHA204A encryption chip detailed use method! Protect your program from plagiarism.)

超声波模块制作了一个测距装置，HC-SR04自身不带温度补偿功能，所以加上一个使用DS18B20做的温度测量模块。整个系统包括：51单片机最小系统，超声波测距模块、温度测量模块、液晶显示模块。(The ultrasonic module has made a distance measuring device, HC-SR04 does not have temperature compensation function, so add a temperature measuring module using DS18B20. The whole system includes 51 single chip microcomputer minimum system, ultrasonic ranging module, temperature measurement module and LCD module.)
