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.)

PMSM 180°正弦波无位置传感器FOC程序(PMSM 180 sensorless FOC program.)

说明：  测温模块使用防水型PT100，显示屏使用1602，使用PID算法控制继电器的开关从而控制加热棒的通断(Temperature measurement module uses waterproof PT100 and display screen 1602. PID algorithm is used to control the switch of relay to control the on-off of heating rod.)

该嵌入式C语言源代码软件工程是以STM32F103系列微控制器为核心的嵌入式数字示波器的源代码工程，主要实现0V基线对齐、探头补偿校准、波形保存和调出等功能，具有带宽0-200KHZ、垂直灵敏度10mv/div-5v/div、记录长度1024点、触发方式自动/常规/单次等参数。(The embedded C language source code software engineering is based on STM32F103 series microcontrollers as the core of the embedded digital oscilloscope source code project, the main realization of 0V baseline alignment, probe compensation calibration, waveform preservation and recall functions, with bandwidth 0- 200KHZ, vertical sensitivity 10mv / div-5v / div, record length 1024 points, trigger mode automatic / conventional / single and other parameters.)

说明：  arm的非向量中断通过执行IsrIRQ判断中断源，找到相应Handle***的地址。 此程序是在arm上实现向量方式中断的初始化程序(arm of the non-vector interruption through the implementation IsrIRQ judgment interrupt source, find the corresponding Handle*** address. This procedure is the arm on the way to achieve vector interrupt the initialization procedures)

说明：  利用STM32F103编写的使用芯片内部自带AD程序，c语言(STM32F103 prepared by using procedures chip comes with AD, c language)
