====== How to activate the 3.2inch LCD shield with your ODROID-XU4 ======

You need a HDMI connection or a Serial console connection to follow below instruction.

<WRAP center round important 100%>
To use the SPI, you first need to update the kernel version to "3.10.83" or higher. 
  sudo apt-get update && sudo apt-get dist-upgrade
"ads7846" module driver must be in the output of "lsmod" command.
</WRAP>

==== How to enable driver (Only Ubuntu 16.04 or higher is required) ====
Edit /etc/modprobe.d/blacklist-odroid.conf to comment out following three ines.
<code>
blacklist spidev
blacklist spi_s3c64xx
blacklist ads7846
</code>

Reboot.
  reboot
Check your SPI node.
  ls /dev/spidev*

===== Configuring framebuffer =====
**0. Update your Kernel**
<code>
sudo apt-get update && sudo apt-get dist-upgrade
</code>

**1. Insert modules**

  sudo modprobe fbtft_device name=odroid32 rotate=90 busnum=1 gpios=reset:21,dc:22 speed=32000000 cs=0

You will have a new frame buffer /dev/fbX.

Find a ili9340 framebuffer node
  ls /dev/fb*
  /dev/fb0
  cat /sys/class/graphics/fb0/name
  fb_ili9340

===== Run Xwindow =====
{{:en:32tft:xorg.png?300|}}

**0. Insert modules**

  sudo modprobe fbtft_device name=odroid32 rotate=90 busnum=1 gpios=reset:21,dc:22 speed=32000000 cs=0

**1. Create a new config file**
  sudo mv /etc/X11/xorg.conf /etc/X11/xorg.conf.old
  
Add following lines in "/etc/X11/xorg.conf" file.
<code>
Section "Device"
    Identifier    "XU4 fbdev"
    Driver        "fbdev"
    Option        "fbdev" "/dev/fb0"
EndSection
</code>

**2. Run**
  /etc/init.d/lightdm start
===== Run Console =====
**0. Insert modules**

  sudo modprobe fbtft_device name=odroid32 rotate=90 busnum=1 gpios=reset:21,dc:22 speed=32000000 cs=0

**1. Run con2fbmap**

con2fbmap <console> <framebuffer>

  sudo apt-get install fbset
  sudo con2fbmap 2 0

Press Keyboard Ctrl + Alt + F2 to change the console screen of FB1\\
There will be a login screen on the LCD screen.

===== Touch Calibration =====
{{:en:32tft:cal.png?300|}}

<WRAP center round important 100%>
To use the Touch Calibration, you first need to update the kernel version to "3.10.96-86" or higher.
  sudo apt-get update && sudo apt-get dist-upgrade
</WRAP>

**0. The xinput-calibrator pakage download**

  sudo apt-get install xinput-calibrator

**1. Remove old calibration data.**

  sudo rm /etc/X11/xorg.conf.d/99-calibration.conf
  
**2. Login**

You need a login to get DISPLAY.\\
If you want auto login.\\
Edit /etc/lightdm/lightdm.conf file to enable auto-login: (password: odroid)

<code>
odroid@odroid:~$ sudo vi /etc/lightdm/lightdm.conf
[sudo] password for odroid: 
odroid@odroid:~$ cat /etc/lightdm/lightdm.conf 
[SeatDefaults]
autologin-user=odroid
autologin-user-timeout=0
odroid@odroid:~$ 
</code>

**3. Check your DISPLAY**

  odroid@odroid:~$ w                                                              
  09:13:31 up 35 min,  2 users,  load average: 0.09, 0.08, 0.12                  
  USER     TTY      FROM             LOGIN@   IDLE   JCPU   PCPU WHAT             
  odroid   ttySAC2                   08:42    2.00s  0.75s  0.02s w               
  odroid   :0       :0               05:39   ?xdm?   1:15   0.63s mate-session    
  odroid@odroid:~$

**4. Run calibrator**

  sudo DISPLAY=:0 xinput_calibrator

Follow the directions on your screen.\\
then, you will get something like\\

{{:en:c1:xinput_calibrator.png?500|}}\\

Copy to "/etc/X11/xorg.conf.d/99-calibration.conf"
  sudo mkdir /etc/X11/xorg.conf.d/
  sudo vi /etc/X11/xorg.conf.d/99-calibration.conf

**5. Reboot**
  sudo reboot
