单片机ad转换，将采集的模拟信号转换成数字信号(Single-chip ad conversion, the analog signal will be collected into a digital signal)

MSP430F5438 flash操作实例程序(MSP430F5438 flash)

stm32下跑通usb外设，编译环境基于keil(stm32 next run through usb peripherals, based on keil compiler environment)

设计并制作用于电池储能装置的双向DC-DC变换器，实现电池的充放电功能，功能可由按键设定，亦可自动转换。(A bidirectional DC-DC converter for battery energy storage is designed and implemented to realize battery charging and discharging functions. The functions can be set by the button and also can be automatically converted.)

官方数据.分享给需要的，欢迎下载，英文的，讲解详细(The RESET pin is an active low bidirectional control signal. It acts as an input to initialize the MCU to a known start-up state, and an output when an internal MCU function causes a reset.The RESET pin has an internal pullup device.)

采用ＰＩＣ单片机解码ＴＶ红外线遥控器程序,程序采用ＰＩＣ１６Ｆ６３０，可以针对大部分遥控器解码．(using PIC microcontroller decoding TV infrared remote control procedures that are used PIC16F630. can address most of the remote control decoder.)

在单片机编程中位图及字库点阵提取程序源代码( The position chart and the fonts lattice withdraw the procedure source code in the monolithic integrated circuit programming )

名称：门禁模拟 模拟现实中门禁系统，可以输入密码进入也可以呼叫住户，再由住户按下开门按键 实现改密码功能，密码保存在24c02中能保证掉电不丢失密码。八个LED灯分别代表 8家住户，其中开门按键为共用，还带有忘记密码恢复按钮，模拟恢复出厂设置， 显示部分为LCD1602。程序共分为3种模式，分别为 等待输入 密码修改 呼叫住户 3种模式，其中等待输入是主要状态，所以在进入密码修改 呼叫住户模式后如果 长时间没有操作能自己切换到等待输入模式。(Name: Access Analog Simulating real access control system, you can also enter a password to enter the call households, again by pressing the open button households Implement change password function, the password stored in the 24c02 can guarantee non-volatile password. Eight LED lights represent 8 households, which opened the door keys are shared, but also with forgotten password recovery button, analog restore factory settings, Display part LCD1602. Program is divided into three modes, namely, waiting for a password to modify call households 3 modes, which is the main input wait state, so call households entering the password change mode if Their long time operation can be switched to the standby input mode.)
