芯片：STC12C5A60S2 晶振：16MHz 波特率：4800bps 引脚定义：串行口1： 发送————TxD/P3.1； 接收————RxD/P3.0 串行口2： 发送————TxD2/P1.3；接收————RxD2/P1.2 功能描述：STC12双串口通信（中断方式） 当串行口1接收GPS数据后(4800波特率)，将此数据由串行口2发送出去 当串行口2接收数据后，将此数据由串行口1发送出去(Chip: STC12C5A60S2 Crystal: 16MHz Baud Rate: 4800bps Pin definitions: Serial port 1: Send TxD/P3.1 receiving RxD/P3.0 Serial port 2: Send TxD2/P1.3 receiving RxD2/P1.2 Function Description: STC12 Two serial communication (interrupt) When a serial port after receiving GPS data (4800 baud), this data is sent out by the serial port 2 When the serial port 2 receives data, this data is sent out by the serial port 1 )

键盘测试，测试键盘的好坏,小测试,够了没(keyboard test)

这段代码包括了基于STM32对简单小车的循迹壁障以及L298N的驱动。并对其中关键部分进行了注释。(This code includes a simple car-based STM32 tracking barrier and L298N driver. And one of the key parts of the notes.)

泰克TDS220示波器使用指导书 ，使用起来很方便，其他示波器使用方法类似(Tektronix TDS220 oscilloscopes use instructions, easy to use, similar to other oscilloscopes use)

本例是基于STM32F407完成对。本代码主要完成MP3播放，界面显示等功能，还可在此基础上外扩点阵屏实现LED显示功能！(This case is based on the completion of the STM32F407. The code is mainly to complete MP3 playback, interface display and other functions, can also be based on the expansion of LED dot matrix screen display function!)

stm32开发lcd显示程序，从sdcard读取数据(stm32 for lcd display ,pic read from sdcard)

说明：  单片机中IIC总线的应用，AT24C02的一个基本例子(IIC bus, microcomputer application, AT24C02 is a basic example of)

测试电脑鼠各个红外探测器的算法，可自行调试(Test each computer mouse infrared detector algorithm, self-debugging)

实时闹钟.1、STM32的实时时钟（RTC）是一个独立的定时器！ 2、RTC模块和时钟配置系统（RCC_BDCR寄存器）是在后备区域，即在系统复位火从待机模式唤醒后RTC的设置和时间维持不变。 RTC这章中，对RTC相关的寄存器的操作特别重要，(RTC Alarm real-time clock timer; keyer; intervalometer; timing device clock; timepiece allocation; configure; collocation; deploy register; tell-table; temporary storage reserve; in support system resetstandby mode awaken; awakening; arouse; rouse; wake up stand)

基于51单片机的PT2314音频功放程序，可实现MIC和音频输入切换及音量音调控制，并用5110显示(Based on 51 single-chip audio amplifier PT2314 program can achieve MIC and audio input switching and volume tone control and display with 5110)
