Designed and tested for raspberry pi with official 7 inch touchscreen.
Other scripts that do the same thing:
- C: https://github.com/WestleyK/rpi-brightness
- Perl: https://github.com/WestleyK/pi-backlight
- Bash/Shell: https://github.com/WestleyK/backlight
Install via go get:
go get -u github.com/WestleyK/rpi-backlight
Or, clone the source code:
cd /tmp
git clone https://github.com/WestleyK/rpi-backlight
cd rpi-backlight/
make
sudo make install
Why install the pre-compiled:
- No dependency needed to install, (not that there is any).
- You don't need golang to compile the source code.
Why not to install the pre-compiled code:
- May not be fully compatible, (could only be partially compatible)
Copy-paste this in your terminal:
wget https://raw.githubusercontent.com/WestleyK/rpi-backlight/master/pre-compiled/armv7l/rpi-backlight
This will install rpi-backlight to the current directory.
To finish the install, do:
chmod +x rpi-backlight
sudo mv rpi-backlight /usr/local/bin/
cd ~/raspberrypi-backlight/rpi-backlight/
sudo make uninstall
Or uninstall manualy:
sudo rm /usr/local/bin/rpi-backlight
