thus , Our development board Keil The development environment has been built , You can start code development .

2.4： Installation and use of serial debugging assistant

Download tool ： http://www.daxia.com/download/sscom.rar

Installation method ： Serial debugging assistant sscom5.13.1 It's installation free , Extract the compressed package and use it directly .

according to PC And terminals , Select the correct serial port . Open the device manager of your computer , You can see it in the port list PC Port number connected to development board .

What I'm showing here is COM63, So we need to sscom Select from tools COM63, Development board program baud rate set to 115200, So I am sscom Serial port tool selection 115200 Baud rate . The screenshot of opening the serial port is as follows ：

2.5： Use Git Download project package

Git Is an open source distributed version control system , Agile for efficient handling of any small or large project .Git yes Linus Torvalds In order to help manage Linux Kernel development for the development of an open source version control software .Git And common version control tools CVS, Subversion And so on , It adopts the way of distributed version Library , No server-side software support required . For specific usage, please refer to the link .

First download Git client ;

https://git-scm.com/

Next, open the client , The software interface is as follows ：

Furthermore, switch to the address folder you want to download to F:\4.Tencent_tiny, I use F:\4.Tencent_tiny; Use the following command to switch to this folder .

$ cd  F:\4.Tencent_tiny

Last , Use the clone command to clone github Download the file on the .

$ git clone https://github.com/OpenAtomFoundation/TencentOS-tiny.git

The download is completed as follows ：

above Git The commands are two relatively simple commands , How do other commands work , You can choose Baidu, Google or Bing by yourself .

2.6： Use Keil IDE Build the first bare metal project

keil The project can be directly opened in the project package downloaded above , The project name I chose is ：

mqttclient_iot_explorer_bh1750

The path address is ：

F:\4.Tencent_tiny\TencentOS-tiny\board\TencentOS_tiny_EVB_AIoT\mqttclient_iot_explorer_bh1750

open KEIL Folder project , Execute compile download .

Open the serial debugging assistant , Check the information , Show ESP8266 Connecting to the network , thus , Can be found in keil IDE Implementation development on ,

2.7： Problems encountered during debugging and handling methods

During the whole debugging process , We also found some problems , Sum up ：

1： The serial port is not recognized ;

The first problem is how to deal with it , If the serial driver is installed successfully , The serial port name is mbed Serial Port, If the serial port with this name is not found in the serial port debugging assistant , This indicates that the driver was not installed successfully ,win10 It can automatically identify ,win7 You need to download the driver .

2： Unable to find downloader ;

The second problem is how to deal with it , The downloader uses WebUSB: CMSIS-DAP, my win7 What is recognized on the system is , An exclamation mark is found , I thought it was useless , But in keil IDE The following is to identify the downloader , So it doesn't matter .

3： The program cannot be downloaded

If the download fails , May be mcu Run away , At this time, you need to configure boot Pin ,boot The configuration table is as follows ：

	boot0	boot1
The default mode ：Flash start-up	0	1
Serial port burn mode	1	0

If your development board can't download the program , hold boot0 Set high , then boot1 Set up 0 , Looking for a bin File or use IDE debugged , And then boot The button reverts to the default mode boot0：0 boot1:1, You can download .
