如何調整樹莓派官方版7吋觸控螢幕亮度

Posted on by Sam Hung

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
