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.)

一份stm32处理器上ADC应用编程的实际例子，附送一份详细pdf源代码说明，说明很清楚，参考价值很大(Stm32 a processor ADC practical examples of application programming, included a detailed pdf source code, note it is clear that a great reference value)

ARM监视串行口，将接收到的字符发送到字符再发送给串口，即按PC机键盘通过超级终端发送数据，开发板将接收到的数据再返还给PC，在超级终端上显示。(ARM monitors the serial port, the received characters are sent to a character and then sent to the serial port, ie the PC keyboard to send data via HyperTerminal, the board will receive the data and then back to the PC, in the HyperTerminal display.)

ATT7053B单相计量芯片程序 ATT7053BU 是一颗带SPI 通讯接口的单相多功能计量芯片（EMU）。 芯片的工作电压范围是4.5 ～ 5.5V。 工作晶振为6MHz。(ATT7053B single-phase metering chip program ATT7053BU of a single-phase multi-function measurement chip with SPI communication interface (EMU). Chip operating voltage range is 4.5 to 5.5V. The work of the crystal is 6MHz.)
