为Raspberry Pi 5B 小屏幕打造屏幕保护程序

Posted on Jul 6, 2024

硬件

Raspberry Pi5
128GB micro sd card
3.5 inch LCD Display
sd卡读卡器

刷入系统

下载镜像烧录器 (Raspberry Pi Imager) https://www.raspberrypi.com/software/

插入sd卡和读卡器选 Raspberry Pi OS Lite(64-bit) 烧录完成将卡插入树莓派5

安装常用软件

更换源:

/etc/apt/sources.list

deb http://mirrors.ustc.edu.cn/debian bookworm main contrib non-free non-free-firmware
deb http://mirrors.ustc.edu.cn/debian-security/ bookworm-security main contrib non-free non-free-firmware
deb http://mirrors.ustc.edu.cn/debian bookworm-updates main contrib non-free non-free-firmware
# Uncomment deb-src lines below then 'apt-get update' to enable 'apt-get source'
#deb-src http://mirrors.ustc.edu.cn/debian bookworm main contrib non-free non-free-firmware
#deb-src http://mirrors.ustc.edu.cn/debian-security/ bookworm-security main contrib non-free non-free-firmware
#deb-src http://mirrors.ustc.edu.cn/debian bookworm-updates main contrib non-free non-free-firmware

/etc/apt/sources.list.d/raspi.list

deb http://mirrors.ustc.edu.cn/raspberrypi/debian/ bookworm main
# Uncomment line below then 'apt-get update' to enable 'apt-get source'
#deb-src http://mirrors.ustc.edu.cn/raspberrypi/debian/ bookworm main

sudo apt update && sudo apt upgrade
sudo apt install vim git tree byobu lm-sensors dnsutils

安装LCD屏驱动

git clone https://github.com/goodtft/LCD-show.git

sudo ./LCD-show/MHS35-show

安装完成后会自动重启

配置自动登录

tty1自动登录

/etc/systemd/system/[email protected]/autologin.conf

[Service]
ExecStart=
ExecStart=-/sbin/agetty --autologin <username> --noclear %I $TERM

systemctl daemon-reload
systemctl restart [email protected]

设置屏保程序

登录自动启动byobu终端程序: ~/.bashrc 添加

# tty login with byobu
if [ -z "$SSH_CONNECTION" ] && [ -z "$SSH_CLIENT" ] && [[ "$(tty)" == /dev/tty* || "$(tty)" == /dev/console* ]]; then
    if [ "$TMUX" = "" ]; then byobu; fi
fi

获取 rest 屏保程序(或使用 cmatrix 等 apt install cmatrix)

https://github.com/rb-plan/rest.git

~/.byobu/.tmux.conf

set -g lock-after-time 600
set -g lock-command "rest"

rpi-rest

使用 fbcon 调整屏幕方向

apt install fbset

fbcon=rotate:<n>
    0：不旋转
    1：旋转 90 度
    2：旋转 180 度
    3：旋转 270 度

在 /boot/firmware/cmdline.txt 文件末尾添加 fbcon=rotate:2

console=serial0,115200 console=tty1 root=PARTUUID=fe7ca83d-02 rootfstype=ext4 fsck.repair=yes rootwait cfg80211.ieee80211_regdom=US fbcon=rotate:2

重启以下 reboot
