Raspberry Pi raspi-config Configuration Tool

Raspi-config is a Raspberry Pi configuration tool designed and maintained by Alex Bradbury for Raspbian Systems.

1. Usage (usage)

When you start Raspbian for the first time, there will be rasp-config hints. To open this configuration tool, simply enter the following command on the terminal:

sudo raspi-config

sudo administrator permissions are required because the files you want to modify are not owned by the PI user.

You will see a blue screen with a gray box with options, similar to the following:

2. Moving AROUND the menu (moving through the menus)

Use the up and down cursor control keys to move the highlight display in optional options. Press the right cursor control key to jump out of the options menu to the bottom of the <Select> and <Finish> buttons. Press the left cursor control key to return to the Options menu. Alternatively, use the TAB key to switch between the sides.

Note In some menus with many options (such as the time Zone city's selection menu), you can directly enter the relevant content of the corresponding option to jump to the corresponding option in the menu. For example, entering "L" will jump to Lisbon and discover that there are only 2 options from London, which avoids the hassle of scrolling through all the options to find out.

3, what Paspi-config DOES (Raspi-config can Do)

Overall, the goal of Raspi-config is to provide a convenient way to modify most of the commonly used configurations. It will automatically modify the corresponding/boot/config.txt and other standard Linux configuration files. There are some options that require the system to be restarted for the settings to take effect. If you modify these options, Raspi-config will ask if you want to restart the system after pressing the <Finish> button.

4. Menu option

4.1 EXPAND FILESYSTEM (extended file system)

If you use Noobs to install the Raspbian system, you can ignore this part because Noobs has automatically extended the file system when installing the system. However, if you are writing the system image file to SD yourself, some of the space on the SD card will not be used. This option can be mounted with an additional capacity of 3GB or more. Select this option to mount all the remaining space on the SD card and provide more space for your files. You need to restart the raspberry send to let this setting take effect. Note that this option does not confirm the process, and the selection will then start expanding the space directly.

4.2 Change user PASSWORD (modify password)

Raspberry Pi Default User is pi, password is raspberry. You can change the pi password here. Other user management can be consulted here.

4.3 Enable boot to desktop or SCRATCH (set boot into desktop or SCRATCH)

You can modify the operation of your Raspberry Pi when it starts. Use this option to modify whether your startup preferences go to the command-line terminal, the desktop environment, or directly into the scratch programming environment.

4.4 Internationalisation option (internationalization options)

Select internationalisation Options, and then click Enter to enter the following sub-menu:

4.4.1 Change LOCALE (modify local properties)

Select a local property, such as EN_GB. UTF-8 UTF-8

4.4.2 Change TIMEZONE (Modify time zone)

Select your own time zone, first select a region such as Europe (Europe), then select a city such as London. You can enter the target character directly to jump to the corresponding option.

4.4.3 Change KEYBOARD LAYOUT (modify keyboard type)

This option will open another menu that allows you to select a keyboard type. It will take a long time to read all the keyboard types. Modifications usually take effect immediately, but may also require a restart.

4.5 Enable camera (webcam enabled)

In order to use the Raspberry Pi camera module, you must enable it here. Select this option, and then select Enable. This will ensure that at least 128M of memory is allocated to the GPU.

4.6 Add to Rastrack (adding rastrack)

Rastrack is a Google map created by a community of Raspberry Pi users to create their own geographic location, showing a map of the world's Raspberry Pi enthusiasts. This was created in 2012 by the young Raspberry Pi enthusiast Ryan Walmsley. You can access Rastrack in rastrack.co.uk.

You can use this option to add your geographic location to this map.

4.7 Overclock (overclocking)

It's possible to overclock your Raspberry Pi CPU. The default frequency is 700MHz, but it can be overclocked to 1000MHz. The frequency you can reach is uncertain, and the high frequency may lead to instability problems. Selecting this option will prompt the following warning:

You should understand that overclocking may cause your Raspberry Pi life to be shortened. If you overclock to a certain frequency causing the system to be unstable, you should try to lower the frequency. Hold down "shift" while the system is booting to temporarily disable overclocking.

4.8 Advanced Options

4.8.1 OVERSACN

There are a lot of different sizes for the old TV screens, and some of the cabinets are also covered on the screen. The picture screen of the TV set uses a black border to ensure that the picture is not lost, which is overscan. Modern TVs and monitors do not require this frame, and the signal is not supported. If the initial text display is beyond the screen display, you need to enable overscan to bring the black border back.

All settings will begin to function after rebooting the system. You can also edit the config.txt directly to make more detailed settings.

In some display cases, especially the monitor, disabling the overscan will allow the screen to fill and correct. There are other situations where you might need to enable overscan and determine its value.

4.8.2 HOSTNAME (host name)

Sets the host name of the Raspberry Pi in the network.

4.8.3 memory split (split RAM)

Modifies the memory allocated to the GPU.

4.8.4 SSH

Enable or disable the use of SSH remote terminal to log in to your Raspberry Pi.

SSH allows you to telnet to your Raspberry Pi using a command line terminal on another computer. Disabling will cause the SSH service to not start to release the program's resources at boot time. More about SSH content reference here. Note SSH is enabled by default. If your Raspberry Pi is connected directly to a public network, you should disable SSH unless you confirm that you have set a password for each user on the Raspberry Pi.

4.8.5 SPI (Serial Peripheral Interface)

Enabling or disabling the automatic loading of the SPI Kernel module requires additional peripheral products such as piface.

4.8.6 Audio (voice)

Force audio output via HDMI or 3.5 mm interface. Please refer to audio configuration for more information.

4.8.7 Update (updated)

Upgrade this tool to the latest version.

4.9 about Raspi-config (on Raspi-config)

Selecting this option will display the following information:

This tool provides a more straightforward way to set the initial configuration of the Raspberry Pi. Although this tool can be run at any time, some of these options may not work if you have already customized your device in depth.

4.10. Finish (completed)

When you have completed your changes and clicked on this button, you will be asked if you want to restart the device. It is best to restart the device if it is used for the first time. If you choose to expand your SD card, there may be a slight delay during the boot process.
