 Dualshock DS4 led colour to show batery status - linux [message #6184] |

Hello, I want to share with you all a small utility I created. As you probably know, when using DS4 controllers, the first one will have the led colour be blue, the second will have the colour be red, and so on. I wanted three things: A. To have the colour be green (it feels more personalized). B. To be dimmer (uses less battery and thus increases use time) C. Indicate battery level and alert when it was almost depleted. So I came up with this small script. It reads the battery capacity and then sets the led brightness accordingly at green colour. When the battery capacity reaches 10%, it will flash the light several times as a way to indicate that it is time to charge it. Currently it only does this for the first joystick/controller. If you have connected/paired more than one, the others are not changed. 1. Save the attached file (a bash shell script) somewhere, eg. ~/Downloads 2. Copy this file to '/usr/local/sbin' with ownership root:root, and set the execute atributes sudo cp Downloads/ds4leds.sh /usr/local/sbin sudo chmod a+x /usr/local/sbin/ds4leds.sh If you now run it from the command line by issuing 'sudo ds4leds.sh' you will see the led brightness dim and set to green, while also reporting some information. 3. What is needed now, is for this script to run periodically every minute. We do this by adding a crontab entry for the root user. sudo crontab -e You will be opening an editor to modify the current crontab for root. In there, add a new line at the very end of that file, and that line should be exactly like this: * * * * * /usr/local/sbin/ds4leds.sh | logger 4. Exit the editor saving the file. Verify that all was saved properly with the command: sudo crontab -l You should see what you just edited in the editor above. And that's it. If you check the syslog, you should find there every minute the same reporting lines that you saw when you ran the script manually.
