Recently turned up the Raspberry Pi I bought before, and decided to pick up the Raspberry Pi combined with the go language that I was learning to engage in things. Here first build the environment to run the GO program.
First, the

When you are running the command, log on with the default user name and password (if you have not modified it ). The Default User of Raspbian is pi, and the default password is raspberry.Step 2:
After you log on, run the following command:
Sudo raspi-config
This command will open Raspberry Pi configuration, as we saw during the first startup.Ste

Installing the Raspberry Pi is only the first step in making Windows IoT core run on the Raspberry Pi, and the complete set of tools such as management systems are essential. Because Windows IoT core runs on a card PC, there are not too many UI actions set up, and many operations are done through the IoT dashboard app
There used to be a lot of users asking us how to build Docker engine and related Debian packages. Maybe they want to try some new features, so they need to get the latest release version as soon as possible.
Here I share how to build the latest Docker version on Raspberry Pi. But note that although it is not very difficult but time-consuming.
So let's start, follow me into the Rabbit cave to explore (_ Tr

There are many common Linux system branches in China:
1. Debian
2. RedHat
Refer:Overview of the evolution of GNU/Linux releases over the years.
At present, the Debian branch of the desktop version is better than the RedHat branch of the server, because the Raspberry

This article describes how to install OpenCV in the Raspberry Pi by compiling the source code, and a simple example of how to use OpenCV. For more information, please refer to-"Raspberry Pi Study notes-index Blog"1. Download several dependencies it is a good idea to update the
address of Raspberry Pi.Run the DOS window and enter ARP-A. The dynamic IP address under Interface 192.168.137.1 is the Raspberry Pi address.Why is the interface 192.168.137.1? Because the "local connection" ip address has been automatically set to static IP 192.168.137.1 when the Internet is shared on the upper part, of course, this IP address can also be set t
Use the command line to set Raspberry Pi's Wi-Fi network
If you have not logged on to the Common graphic user interface, This method is suitable for setting Raspberry Pi's wifi. Especially when you do not have a screen or wired network, you only use the serial control line. In addition, this method does not require additional software, and everything is included
general software conversion efficiency is relatively low, Raspberry Pi CPU is relatively poor, the conversion time is longer.
Later, I found a better solution. I used the software mpg123 to decode it and output it to the terminal. Then, it was converted to WAV format. Then, the pifm program of
software package is ready and can be released;
Iii. Cross-compiling source code
1. Environment
Ubuntu
2. Install Raspberry Pi cross compiling tool
Step1. download Raspberry Pi cross compiler tool https://github.com/raspberrypi/tools
Step 2: place the source code in a folder
that can connect to the HDMI interface, or a monitor that transfers the VGA interface using the active HDMI to VGA module.
2. Software SettingsWrite the Windows IoT Core system image for Raspberry Pi, note that the version is more than 14986, preferably the latest version 15026. Insert the system-burning TF card into the
