Setting up the Raspi

Setting Up The Raspi

Establish Wifi, Bluetooth.

Credentials are pi@raspberrypi.local and raspberry. KiTTY seems to be a good terminal.

Set Up WiFi without Screen

Into root directory:

• Add an empty file called ssh
• Add a file wpa_supplicant.conf which includes

country=ee 
update_config=1
ctrl_interface=/var/run/wpa_supplicant GROUP=netdev
network={
    scan_ssid=1
    ssid="YOUR_NETWORK_NAME"
    psk="YOUR_PASSWORD"
    key_mgmt=WPA-PSK
}

Note the (Notepad++: Edit) EOL conversion UNIX.

USB cable // Perhaps requires Zero

Connect via usb to gadget mode. After flashing RaspianOS. The following files are at boot-directory

• Modify config.txt: add dtoverlay=dwc2
• Add an empty file called ssh
• Edit cmdline.txt: Ensure that there exist rootwait modules-load=dwc2,g_ether.

Now you can ssh pi@raspberrypi.local if the usb cable is plugged in.

Raspi and VIM

Vim-nox is the (enhanced) minimal vi editor. Does not have a GUI, but includes the mouse support, but not the clipboard. Install vim and vim-nox. Some different vim plugin managers are

• vim-plug. Minimalist. Load plug.vim when vim starts (.vim/autoload). Instructions to install at https://www.linuxfordevices.com/tutorials/linux/vim-plug-install-plugins. Use the command :PlugInstall to install.
• vundle (updated 2019)
• pathogen
• dein.vim
• volt
• janus
• minpac

After updating .vimrc or my_configs.vim remember to source the file: :source %. Some important thing in vim ~/.vimrc

• syntax enable
• set expandtab
• set tabstop=2
• set incsearch
• set hlsearch

Two-column view: Ctrl-w v. The scrollbind is: set scrollbind. Command ^w l goes to new split, and also ^w arrows work.

Latex on vim: I use vim-latex @ https://github.com/vim-latex/vim-latex. Use Plug 'https://github.com/vim-latex/vim-latex' between call plug#begin() and call plug#end() and install with :PlugInstall.
