1、 Smart cloud account registration and creation of new products

1.1、 Account registration and its smart cloud usage documents

I won't elaborate on account registration ,http://docs.gizwits.com/zh-cn/overview/overview.html Smart cloud Document Center . You can find some information you need .

1.2、 Product creation

Choose the network access method ：

View basic product information ：

The data points ：
Data points must be writable .

1.3、 Data reading and writing types

   Reading and writing types ： Define the scope of data points , contains 4 Types , Namely ： read-only 、 Can write 、 Call the police 、 fault ,
The following is the official introduction to reading and writing types ：
  ① read-only ： Indicates that the data point is non control , Data can only be reported from the device .
  ② Can write ： Indicates that the data point can be controlled . The device can report data points , Cloud / client ( Mobile ) For this number
Control the distribution of site data .
  ③ Call the police ： Indicates that the data point is not controlled , Data only supports slave devices ( Device end ) Report , The data type needs to be Boolean .
  ④ fault ： Indicates that the data point is not controlled , Data only supports slave devices ( Device end ) Report , The data type needs to be Boolean .
The cloud makes statistics on the data point reported by the device , Can be found in “ Running state ” see .
   data type ： Define data point data types , Contains Boolean values 、 Enumeration type 、 The number 、 And extension , The following is the official introduction to data types ：
  ① Boolean value ： Two states ： 0 or 1. Such as switch state , It is recommended to use Boolean data type .
  ② Enumeration type ： A finite set of values can be defined . When defining a function ( components and parts ) There are fixed values ,
   for example ：“ Set up LED Combine colors ” The enumeration definition value of this data point ：“ Customize , yellow , violet , Pink ”.
  ③ The number ： Fill in the range of values , The value can be negative / decimal , Smart cloud automatically converts numeric values to positive numbers .
  ④ Expand ： Fill in the data length , The data content is user-defined . For complex functions that cannot be satisfied by the above function points , Smart cloud does not recommend using this type of data , Data report the data of this data point , Smart cloud cannot recognize .

1.4、MCU Development

Product Secret You can see in the basic information above .

Download code ：

2、 You can use virtual devices to debug

mobile phone app Download address ：
https://download.gizwits.com/zh-cn/p/98/99 The official download address of smart cloud .

   Now you can use mobile phones and virtual devices for simple debugging .

3、esp-01s Burning machine smart cloud firmware

3.1、 Firmware download

   Firmware download https://download.gizwits.com/zh-cn/p/92/94 Download the firmware of smart cloud directly . because GAgent The firmware will be updated from time to time , Maybe the time you see will be different , Subject to the latest release on the official website , You can also download the old firmware .

Unzipped firmware file ：
You can see that there are several types of firmware , The red That's the firmware we need to burn , I burn the packaged firmware directly , I see someone on the Internet publishing firmware that is not packaged , It's a little troublesome to burn .

   Burning software download address ：http://wiki.ai-thinker.com/esp_download

Download and decompress to see the burning software ：

   After burning the firmware of Ji Zhi cloud, I still want to restore the firmware of Le Xin , Attached download address .
Lexin firmware download address ：http://wiki.ai-thinker.com/esp8266/sdk

3.2、esp-01s brief introduction

A physical picture ：

Pin distribution ：

3.3、 burn

3.4、esp And STM32 Pin connection

Pin connection ：

Other pins can be suspended .

4、 Program migration MCU

My own engineering documents ：https://download.csdn.net/download/weixin_45488643/12558122

4.1、 Engineering configuration

   I have downloaded the app folder of smart cloud , Decompress and you can see the following files ：

Put this 2 Copy folders to your project file .
I use punctual code myself .

Add folder and file path to the project file .


choice C99 Mode Prevent compilation errors .

4.2 The code migration

Project folder directory ：
Timer used 3 And serial port 3.

4.2.1、 modify USART3 file

   stay usart3.c Add serial port to the file 3 Initialization and interrupt service functions , Write the interrupt received data to gizPutData() function , The code is as follows ：
   Add header file #include “gizwits_product.h” To USART3 In the document , If you don't add it, you will report an error .

4.2.2、 modify timer.c file

   At the timer 3 Add... To the interrupt service function gizTimerMs() function , And add gizwits_product.h The header file , The code is as follows


Be careful ： gizwits_product.h There is no reference to... In the file gizTimerMs() Function declaration , You need to add , Otherwise, an alarm will appear during compilation .

4.2.3、 modify gizwits_product.c file

   After adding the serial port sending function , go back to gizwitsEventProcess() Add our user event logic to the user event handling function , Here we are controlling LED1 On and off , stay EVENT_LEDonoff Add its... According to the returned switching value in the event LED1 Switch control of , The code is as follows ： You need to add your own definition in advance LED Header files and usart3.h The header file , Otherwise, it will be wrong .

stay mcuRestart() Add soft reset function to function , The code is as follows ：

modify **userHandle()** function ：
Add data reporting .

   In the main function , First press the key 、 LED、 Serial port and Gizwits Timer required by serial port protocol 、 WIF A serial port 、 Data buffer and a series of initialization , The main loop scans the function by pressing the key KEY_Scan Always scan the current key status ,KEY1 Press to make WIFI The device has reached the AirLink Distribution network mode , KEY_UP Press to let WIFI The device enters reset mode （ Clear pairing information 、 disconnect ）, and UserHandl Function reads the current LED1 state , Assign the read state value back to the device data structure variable , And then through gizwitsHandle Function to report to the server .

5、 Burning engineering distribution network

Download the project file to the development board .

5.1、 A physical picture

5.2、 Distribution network

Distribution network ：



   First press... On the development board KEY1 The key in , Click I have completed the above operation .

5.3 、 Physical effect display

Turn on the lights. ：


   Friends who can see this place are also more patient , The project documents were sent free .
Free download address of engineering documents ：https://wwa.lanzous.com/iVf8re42hvi

   This is the end of the whole project , I hope you can show mercy , Give me one Fabulous .
