Driver Installation

  • Download raspbian image.
    https://www.raspberrypi.org/downloads/raspbian/
  • Tulis raspberry image ke sdcard.
  • Buka terminal, install driver lcd pada Raspberry Pi.
    git clone https://github.com/goodtft/LCD-show.git
    chmod -R 755 LCD-show
    cd LCD-show/
    sudo ./LCD35-show
  • Tunggu beberapa saat, Raspberry Pi akan reboot dengan sendirinya.

Touch screen calibration

Touchscreen dapat dikalibrasi dengan menggunakan program xinput_calibrator.

cd LCD-show/
sudo dpkg -i -B xinput-calibrator_0.7.5-1_armhf.deb

Setelah instalasi selesai, buka Preference->Calibrate Touchscreen. Ikuti perintah yang muncul pada layar. Jika kalibrasi selesai, copy parameter yang dihasilkan pada file 99-calibration.conf, kemudian simpan di folder /ect/X11/xorg.conf.d/.

/ect/X11/xorg.conf.d/99-calibration.conf

Problem Solving

  • Jika touchsreen antara x dan y tertukar, dapat diatasi dengan solusi berikut ini:
    sudo nano /boot/config.txt
    dtoverlay=piscreen,speed=16000000,rotate=90
    reboot
  • Jika x axis posisinya dalam keaadan mirror, dapat diatasi dengan solusi memasang evdev.
    apt-get install xserver-xorg-input-evdev

    Ganti urutan file pada folder /usr/share/X11/xorg.conf.d. Hal ini dilakukan agar konfigurasi evdev tidak tertimpa (overide) dengan konfigurasi libinput. Ganti angka evdev.conf lebih tinggi dari pada libinput.conf.

    cd /usr/share/X11/xorg.conf.d
    sudo mv 10-evdev.conf 45-evdev.conf
    reboot
