stm32 128M NANDFlash 管理程序 自定义坏块管理 (stm32 128M NAND Flash bad block management program custom management)

说明：  共5个文件。2个描述了一些时钟的初始化以及时钟的使用。2个描述了UART的使用。一个文件是一个简单的使用示例。(This zip file contains the simple code to control the stm32 components. It tells how to initialize the clock module, use the clock module, and how to do the same thing to UART.)

基于STM32F10X系列GPS模块应用程序，真正实现GPS秒脉冲信号校准时间，实现ms级别精确对时（GPS接收信号本来只能实现秒级对时）(Based STM32F10X series GPS module application, real time GPS second pulse signal calibration to achieve the level of precision of the time ms (GPS reception signal had only seconds to realize when))

简单实现OBD读取功能，stm32f103的主控芯片(Simple implementation of OBD read function)

基于STM32微控制器，利用MS5540C设计的高度传感器。(Based STM32 microcontrollers, designed by MS5540C height sensor.)

在KEIL开发的ARM之Cortex-M3核例程 LPC1788之DAC例程(KEIL development of the ARM Cortex-M3 core routines LPC1788 DAC routine)

基于51单片机的电能表软件设计，电能测量芯片是ATT7022C，有完整的读写和校表程序，已通过测试。(SCM based on the 51 Meter software design, power measurement chip ATT7022C, and write a complete calibration procedures, it has been tested.)

使用基于STM32f103驱动SSD1306的OLED（0.96寸）演示动画驱动，包含整个工程文件(Based STM32f103 drive SSD1306 of OLED (0.96 inch) driven animation, contains the entire project file)

这是一个基于mini2440触屏显示的代码，可以修正mini2440包括语言、触点等等的信息(This is a code-based mini2440 touch display can be corrected mini2440 including language, contact information, etc.)

说明：  基于STM32和W5500 的阿里云平台MQTT连接，内置了HMAC-SHA1算法，可以直接填写阿里云物联网平台的三个参数，程序直接生成域名、账户名、密码以及Topic。软件还包含基于Cjson的json构建与解析。(Based on STM32 and W5500, the MQTT connection of Aliyun platform is built-in with HMAC-SHA1 algorithm, which can fill in three parameters of Aliyun Internet of Things platform directly. The program generates domain name, account name, password and Topic directly. The software also includes JSON construction and parsing based on Cjson.)
