LCD8000-70T Display Configuration

1） The connection of LCD8000-70T and RIoTboard will be finished through the LCD-Ex

extension board, the way of which can be seen as below:

Figure 1 Hardware Connections

Mote:

 On using 50PIN FPC cable to connect LCD and LCD-Ex, the blue side should be

upward;

 It does not support the powered plug-in and plug-out.

2） Please connect the red, green and black wires of UART8000-U respectively to the

corresponding pins of J18 connector on RIoTboard as illustrated in the following figure;

5） Set the display mode

Under the u-boot, 7-inch LCD display mode can be set by executing the following instructions:

 MX6Solo RIoTboard U-Boot > setenv bootargs console=ttymxc1,115200

init=/init nosmp video=mxcfb0:dev=lcd,7inch_LCD,if=RGB565 video=mxcfb1:off fbmem=10M vmalloc=400M androidboot.console=ttymxc1 androidboot.hardware=freescale calibration

 MX6Solo RIoTboard U-Boot > saveenv

6） Set the touch screen

Ubuntu

a) On entering the system, the following command can be used to unload

synaptics driver

 root@linaro-ubuntu-desktop:~# sudo apt-get remove

xserver-xorg-input-synaptics

b) Input the following instructions to install tslib

 root@linaro-ubuntu-desktop:~# sudo apt-get install

xserver-xorg-input-tslib libts-bin

At the execution of this command, network needs to be connected. In additional, you can download ubuntu-touchscreen.zip from Embest website to install tslib. On unzipping, copy to U-disk and connect

U-disk to RIoTboard. Then execute the following instructions:

 root@linaro-ubuntu-desktop:~# dpkg -i libts-bin_1.0-9_armel.deb  root@linaro-ubuntu-desktop:~# dpkg -i

xserver-xorg-input-tslib_0.0.6-7_armel.deb

c) Restart the development board and execute the following instructions

after entering the system:

 root@linaro-ubuntu-desktop:~# TSLIB_TSDEVICE=/dev/input/event0  root@linaro-ubuntu-desktop:~# TSLIB_CONFFILE=/etc/ts.conf  root@linaro-ubuntu-desktop:~# export TSLIB_TSDEVICE

TSLIB_CONFFILE

 root@linaro-ubuntu-desktop:~# ts_calibrate

# At this time a calibration interface will pop up on the screen. Finish

the calibration as per the prompt

 root@linaro-ubuntu-desktop:~# sync

d) Restart the development board and the touch screen can be used

normally.

Android

Keep on starting after the display has been set, the system will automatically pop up the calibration interface, touch all the “+” marks on the screen by following the information shown on the screen to finish calibration.

LCD8000-43T which is used in the Android system before now will be displaced by LCD8000-70T now. After the 7-inch LCD display mode has been set, the following instructions need to be executed when you enter the system:

 root@RIoTboard_6solo:/ # rm /data/system/calibration  root@RIoTboard_6solo:/ #sync
