[Hua Diao Experience] 02 Simple use of Xingkong board [Copy link]

 

 

When I woke up in the morning, while watching Wangzai’s father’s video, I accidentally learned that the main control chip of the Xingkong board was produced by a company in Fuzhou. As a Fuzhou native, I feel a little proud. It seems that it is fate.

So I searched online and found that the main controller of the Xingkong board is a quad-core CPU designed and produced by Rockchip Technology Co., Ltd. in Fuzhou. The model is RK3308 Arm 64-bit quad-core with a main frequency of 1.2GHz.

In yesterday’s post “01 Getting Started with Xingkong Board”, one of the features of Xingkong Board was introduced, which is “2-step programming” and “menu switching, simple, fast and convenient”. Today’s topic is “Easy to Use”. In fact, both are talking about the same thing.

Over the past few years, I have accumulated a lot of development boards. In my impression, you need to build a development environment before using a development board. I remember the first time I came into contact with the ESP-01S development board, I kept failing when downloading the development board library. I persisted in downloading it, and finally installed the 2.5.2 version at that time on the seventh time. I ran the program many times, but it still resulted in "compilation error". Later, I used graphical programming (learning while playing) and simulation programming (Linkboy) to barely pass a series of experiments.

Unlike other development boards, the Xingkong board does not require setting up a development environment first. It can be used as soon as it is turned on. The first thing is a smart terminal. The Xingkong board has a deeply customized system interface based on Linux. The Linux desktop is cancelled in the system and replaced with a home main menu. Long press the Home button to enter the menu, the AB buttons control the cursor to move up and down, and the Home button confirms. This is not only easy to use, but also saves memory and improves efficiency. The main menu of the Xingkong board system provides eight commonly used functions for controlling the board:
1. View the usage tutorial
2. Switch running programs
3. Application switch
4. View network information
5. View system information
6. Switch wireless hotspot mode
7. Calibrate the touch screen
8. Exit

For these eight functions, I think you should calibrate the touch screen first, haha, don't make any mistakes in positioning. The interface after clicking on it is like this.

eagler8

Enter the touch screen calibration utility, touch the crosshairs to calibrate, and after touching five points, the system automatically restarts and comes to the initial page (presumably the calibration is completed).

eagler8

Open function 5 and check system information. You can see the system version: V0.2.8, CPU usage 1%

System version: Displays the current system version
CPU usage: Displays the current CPU usage
Memory usage: Displays the current memory usage
Hard disk usage: Displays the current hard disk usage

eagler8

Open function 1 and view the tutorial, which contains links and QR codes.

eagler8

Open function three, application switch, there are 5 options

This menu item provides the function of turning on and off built-in applications:
Jupyter: Turn on and off the Jupyter python editor service, which is off by default
SIoT: Turn on and off the SIoT IoT server, which is on by default
File sharing: Turn on and off the samba file sharing function, which is on by default
Screen sharing: Turn on and off the VNC screen sharing function, which is on by default Start
automatically at power on: After turning it on, the board will automatically run the program that was running before the last shutdown when it is powered on, which is off by default

eagler8

Open function six and switch on wireless hotspot mode.
After enabling, the hotspot name is: PB772613, and the login password is: 65593640

This menu can turn on and off the wireless hotspot mode on the Xingkong board. When it is started, the hotspot name and password of the board will be displayed. Other devices can search for this hotspot and connect to the board (the device will be disconnected from the network). At this time, the fixed IP of the board is 192.168.123.1

eagler8

Open function 4 and check network information.
You can see that the IP of the wireless hotspot is: 192.168.123.1

This menu provides the function of viewing the network IP:
USB network port: displays the IP address of the board when the board and the computer are connected using a USB cable, which is fixed to 10.1.2.3
Wireless connection: displays the address assigned to the board when the board is connected to other Wi-Fi hotspots, and the IP is assigned by the router
Wireless hotspot: displays the IP address of the board when the board turns on the wireless hotspot mode, which is fixed to 192.168.123.1
Other devices: displays the IP addresses that appear in other situations, such as the address assigned when other network card devices are connected to the board, and the IP is assigned by the router

Here we try to connect the Xingkong board with a mobile phone.
Turn on the mobile phone WIFI, find the Xingkong board hotspot PB772613, and enter the password 65593640

eagler8

Already connected to the hotspot

eagler8

Open the mobile browser and enter 192.168.123.1 to enter the homepage of Xingkong Board

eagler8

Enter the WIFI settings and connect the board to the Internet

eagler8

Open function 4 and check the network information.
You can see that the IP of the wireless connection is: 192.168.28.147
