Alientek USB Touch Screen not work
I bought some 7 inch HDMI screen(800*480 manufacturer-Alientek) with USB controlled touch screen.( http://www.aliexpress.com/item/New-7-inch-USB-Capacitive-Touch-Screen-LCD-Display-HDMI-for-Raspberry-Pi-Pi2-Wholesale/32607731510.html )
HDMI screen can be displayed on Orange Pi One (Armbian 3.4.112-sun8i) using h3disp command.
Touch screen could not work on Orange Pi, but that works on linux i386(4.2.0-38-generic).
The symptom is as follows.
Touch screen is defined ad /dev/usbdev
Thanks tkaiser and psbkkim.
This works perfectly for my new 7inch HDMI display and Orange Pi One running Armbian 5.14 (legacy kernel).
Steps followed:
sudo nano /etc/modules
+hid_multitouch
cp /boot/script.bin .
bin2fex script.bin script.fex
sudo nano script.fex
-fb0_width = 0
-fb0_height = 0
+fb0_width = 1024
+fb0_height = 600
sudo fex2bin ./script.fex /boot/script.bin
sudo shutdown -r now
