樹莓派螢幕畫面及觸控旋轉設定

1. 畫面顯示旋轉

1.1 更新作業系統版本

1.1.1 檢查作業系統版本,輸入以下指令

cat /etc/os-release

輸出如下:

PRETTY_NAME="Raspbian GNU/Linux 10 (buster)"
NAME="Raspbian GNU/Linux"
VERSION_ID="10"
VERSION="10 (buster)"
VERSION_CODENAME=buster
ID=raspbian
ID_LIKE=debian
HOME_URL="http://www.raspbian.org/"
SUPPORT_URL="http://www.raspbian.org/RaspbianForums"
BUG_REPORT_URL="http://www.raspbian.org/RaspbianBugs"

1.1.2 若作業系統是 Raspberry Pi OS Bullseye 分支版本,則需要更新,執行以下指令,其他系統不需要,可以跳過。

sudo apt-get update
sudo apt-get full-upgrade

1.2 Raspberry Pi OS 和 Kali 畫面顯示旋轉

先檢查系統是否有加載 KMS 或 FKMS 驅動。

查看方法:在 /boot/config.txt 中,看對應的主板是否有打開 dtoverlay=vc4-kms-v3d 或 dtoverlay=vc4-fkms-v3d。

1.2.1 若有加載 KMS 或 FKMS 驅動,使用以下命令進行畫面顯示旋轉:

sudo nano /etc/xdg/lxsession/LXDE-pi/autostart

在 autostart 檔案尾端輸入對應顯示旋轉角度的指令如下,重啟後生效

0:旋轉0度

1:旋轉270度

2:旋轉180度

3:旋轉90度

xrandr -o 1

1.2.2 若没有加載 KMS 或 FKMS 驅動,使用以下命令進行畫面顯示旋轉:

sudo nano /boot/config.txt

在 config.txt 檔案尾端輸入對應顯示旋轉角度的指令如下,重啟後生效

0:旋轉0度

1:旋轉90度

2:旋轉180度

3:旋轉270度

display_rotate=3

2. 觸控旋轉

2.1 安裝 libinput

sudo apt-get install xserver-xorg-input-libinput

如果你安裝的是 Ubuntu 系統,或是 Jetson Nano,安裝指令如下,

sudo apt install xserver-xorg-input-synaptics

2.2 在 /etc/X11/ 下建立 xorg.conf.d 資料夾(若該資料夾已存在,此步驟可跳過)

sudo mkdir /etc/X11/xorg.conf.d

2.3 複製 40-libinput-conf 檔案到剛建立的資料夾底下

sudo cp /usr/share/X11/xorg.conf.d/40-libinput.conf /etc/X11/xorg.conf.d/

2.4 編輯該檔案

sudo nano /etc/X11/xorg.conf.d/40-libinput.conf

2.5 找到 touchscreen 的部分,在裡面增加以下指令,然後存檔即可

Option "CalibrationMatrix" "0 1 0 -1 0 1 0 0 1"

類似下圖位置:

2.6 重啟樹莓派

sudo reboot

完成以上步驟即可進行 90 度旋轉。

備註:
90 度旋轉: Option “CalibrationMatrix” “0 1 0 -1 0 1 0 0 1”

180 度旋轉: Option “CalibrationMatrix” “-1 0 1 0 -1 1 0 0 1”

270 度旋轉: Option “CalibrationMatrix” “0 -1 1 1 0 0 0 0 1”

如何設定樹莓派電容式觸控螢幕右鍵快顯功能表

測試環境:2022-04-04-raspios-bullseye-armhf 32 位元系統
支援型號:微雪電子DSI LCD、DPI LCD和HDMI LCD電容式觸控螢幕系列

一、安裝軟體

wget https://www.waveshare.net/w/upload/1/18/Evdev-right-click-emulation.zip
unzip Evdev-right-click-emulation.zip
cd evdev-right-click-emulation
sudo apt install build-essential libevdev2 libevdev-dev
cd 'evdev-right-click-emulation'
sudo cp 'out/evdev-rce' '/usr/local/bin/'
sudo chmod +x '/usr/local/bin/evdev-rce'

執行指令

sudo evdev-rce

執行上列指令後,長按觸控螢幕即可出現右鍵快顯功能表

二、設定 pi 用戶可以執行

sudo usermod -G 'input' -a pi
echo 'uinput' | sudo tee -a /etc/modules
sudo nano /etc/udev/rules.d/99-uinput.rules

在 99-uinput.rules 檔案中增加下列這行

KERNEL=="uinput", MODE="0660", GROUP="input"

儲存後再執行

sudo udevadm control --reload-rules
sudo udevadm trigger

重新開機

sudo reboot

執行指令(不需要 sudo)

evdev-rce

執行上列指令後,長按觸控螢幕即可出現右鍵快顯功能表

三、設定開機啟動

輸入以下指令

sudo mkdir ~/.config/autostart
sudo nano ~/.config/autostart/right_click.desktop

在 right_click.desktop 增加程式碼如下

[Desktop Entry]
Version=1.0
Type=Application
Name=evdev-rce
GenericName=Enable long-press-to-right-click gesture
Exec=env LONG_CLICK_INTERVAL=1000 LONG_CLICK_FUZZ=200 /usr/local/bin/evdev-rce
Terminal=true
StartupNotify=false

如果要修改靈敏度可以修改 LONG_CLICK_INTERVAL=1000 LONG_CLICK_FUZZ=200 這兩個參數值的大小

如何關閉樹莓派螢幕保護程式

一、開啟 lightdm.conf

sudo nano /etc/lightdm/lightdm.conf

二、修改 lightdm.conf

找到[Seat:*]底下”xserver-command=X “,取消註釋,修改如下:

[Seat:*]
...
xserver-command=X -s 0 -dpms

-s # :關閉螢幕保護程式
dpms :關閉電源管理

三、重新啟動即可

sudo reboot

四、備註:設定螢幕開啟或關閉

vcgencmd display_power 0
vcgencmd display_power 1

如何安裝樹莓派虛擬鍵盤

1. 安裝所需軟體matchbox-keyboard

sudo apt update
sudo apt install matchbox-keyboard

2. 開啟編輯toggle-matchbox-keyboard.sh腳本

sudo nano /usr/bin/toggle-matchbox-keyboard.sh

3. 複製以下內容至toggle-matchbox-keyboard.sh腳本,存檔後退出

#!/bin/bash
#This script toggle the virtual keyboard
PID=`pidof matchbox-keyboard`
if [ ! -e $PID ]; then
killall matchbox-keyboard
else
matchbox-keyboard &
fi

4. 新增執行權限

sudo chmod +x /usr/bin/toggle-matchbox-keyboard.sh

5. 開啟編輯toggle-matchbox-keyboard.desktop桌面捷徑

sudo mkdir /usr/local/share/applications
sudo nano /usr/local/share/applications/toggle-matchbox-keyboard.desktop

6. 複製以下内容至toggle-matchbox-keyboard.desktop,存檔後退出

[Desktop Entry]

Comment=Toggle Matchbox Keyboard`
Exec=toggle-matchbox-keyboard.sh
Type=Application
Icon=matchbox-keyboard.png
Categories=Panel;Utility;MB
X-MB-INPUT-MECHANSIM=True

7. 使用”pi”用戶權限開啟編輯panel文件,注意此處不可以用管理員權限執行,否則會找不到檔案

sudo nano /etc/xdg/lxpanel/LXDE-pi/panels/panel

8. 在panel文件中找到類似以下區塊,注意不同版本圖示可能會有些微差異

Plugin {
type = launchbar
Config {
Button {
id=lxde-screenlock.desktop
}
Button {
id=lxde-logout.desktop
}
}

9. 新增以下內容至Button區塊,以新增虛擬鍵盤按鍵

Button {
id=/usr/local/share/applications/toggle-matchbox-keyboard.desktop
}

10. 完成後檔案內容大致如下,存檔後退出

RPILCD-INSTALL-KEYBOARD01.png

11. 重開機後應該可以看到螢幕左上角多了1個虛擬鍵盤圖示

sudo reboot

PCA9685簡介

PCA9685簡介

The PCA9685 is an I2C-bus controlled 16-channel LED controller optimized for LCD Red/Green/Blue/Amber (RGBA) color backlighting applications. Each LED output has its own 12-bit resolution (4096 steps) fixed frequency individual PWM controller that operates at a programmable frequency from a typical of 40 Hz to 1000 Hz with a duty cycle that is adjustable from 0 % to 100 % to allow the LED to be set to a specific brightness value. All outputs are set to the same PWM frequency.

PCA9685 also has a built-in oscillator for the PWM control. However, the frequency used for PWM control in the PCA9685 is adjustable from about 40 Hz to 1000 Hz as compared to the typical 97.6 kHz frequency of the PCA9635. This allows the use of PCA9685 with external power supply controllers. All bits are set at the same frequency. The PCA9685 has 4096 steps (12-bit PWM)

如何調整樹莓派官方版7吋觸控螢幕亮度

如何調整樹莓派官方版7吋觸控螢幕亮度

是否覺得樹莓派的觸控螢幕太亮了呢?

想要調整亮度卻找不到按鈕呢?

其實驅動程式就有提供 /sys/ 界面,讓使用者可以透由指令啟動或關閉螢幕,也可以調整螢幕亮度喔,詳細內容如下:

  1. 啟動螢幕:

    echo 0 > /sys/class/backlight/rpi_backlight/bl_power

  2. 關閉螢幕:

    echo 1 > /sys/class/backlight/rpi_backlight/bl_power

  3. 調整亮度:

    echo n > /sys/class/backlight/rpi_backlight/brightness
    這裡的n是 0 到 255的任一值

  4. 若出現 “Permission denied” 錯誤訊息,請在最前面加上 sudo bash -c 及” “,如:

    sudo bash -c "echo 0 > /sys/class/backlight/rpi_backlight/bl_power"

  5. 備註:’brightness’ 設定只對 v1.1版硬體有效,v1.0版 < 128 是關,>= 128 是開

Pinout has teamed up with Pimoroni to create a prototype board compatibility tool, check it out here!

Explore HATs & pHATs

We’ve added a board explorer! Use it to find the pinout for a Raspberry Pi add-on board, or discover new ones. If you manufacture boards, we’d love to add yours too. You can contribute over on GitHub.

What do these numbers mean?

  • BCM – Broadcom pin number, commonly called “GPIO”, these are the ones you probably want to use with RPi.GPIO and GPIO Zero
  • WiringPi – Wiring Pi pin number (shown as a tooltip), for Gordon Henderson’s Wiring Pi library
  • Physical – Number corresponding to the pin’s physical location on the header
  • Rev 1 Pi – Alternate BCM numbers for the original, 26-pin model “A” and “B” Pi
