It's possible it works on Pi 3 too. Will not work on Pi 2 or 1.\n\n#### Installation Instructions\n```bash\n$ git clone https://github.com/ardera/raspberrypi-fast-ts.git\n$ cd raspberrypi-fast-ts\n$ make\n$ sudo make install\n```\n\nAfter that, the driver is installed, but not yet enabled. To enable it and disable the old driver, see the following steps. *Be aware this makes changes to `/boot/config.txt`.* The installation script is rather dumb. If your `config.txt` is heavily modified, you can apply the changes manually, just look at how the Makefile does it.\n```bash\n$ sudo make enable\n```\n\nIf you specified `lcd_rotate=2` inside `/boot/config.txt` to rotate your display by 180 degrees, you also need to invoke `raspberrypi-fast-ts` with the `-f` option.\n1. Open `/etc/systemd/system/raspberrypi-fast-ts.service` using your favorite text editor\n2. find the line where it says `ExecStart=/usr/local/bin/raspberrypi-fast-ts`\n3. change it to `ExecStart=/usr/local/bin/raspberrypi-fast-ts -f`\n\nAfter a reboot, the new driver will be used.\n\n#### Switching back to the old driver\nTo switch back to the old driver:\n- remove the 5 last lines of `/boot/config.txt`\n- remove the `uinput` line from `/etc/modules`\n- run `sudo systemctl disable raspberrypi-fast-ts.service`\n\n#### Backlight interface\nThis driver now has a backlight interface similiar to the standard sysfs one.\nIt's located inside `/var/tmp/raspberrypi-fast-ts`. Currently, `bl_power` and `brightness` are supported.\n\nYou can use it just like the sysfs interface, for example to change the brightness to 50%:\n```\n$ sudo bash\n# echo 127 \u003e /var/tmp/raspberrypi-fast-ts/brightness\n# exit\n```\n\nto change it to 100% again:\n```\n$ sudo bash\n# echo 255 \u003e /var/tmp/raspberrypi-fast-ts/brightness\n# exit \n```\n","funding_links":[],"categories":[],"sub_categories":[],"project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fardera%2Fraspberrypi-fast-ts","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fardera%2Fraspberrypi-fast-ts","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fardera%2Fraspberrypi-fast-ts/lists"}
