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

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

樹莓派 Raspberry Pi GPIO 排針輸出腳位互動式教學

樹莓派 Raspberry Pi GPIO 排針輸出腳位互動式教學

The comprehensive GPIO Pinout guide for the Raspberry Pi.

This GPIO Pinout is designed to be both a quick and interactive reference to the Raspberry Pi GPIO pins, plus a comprehensive guide to your Raspberry Pi’s GPIO interfaces. It also includes dozens of pinouts for Raspberry Pi add-on boards, HATs and pHATs.

Support Pinout.xyz On Patreon

If you love Pinout, please help me fund new features and improvements. Head on over to Patreon.com/gadgetoid. A $1 pledge will make all the difference! Thank you.

pHAT Stack

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
