To setup the LCD, you need the component below:
1. A panel with LVDS interfaces.
2. An inverter for panel’s backlight power.
3. A LCD cable and an inverter cable.
For the cables, please follow the pin assignment of the connector to make a c able, becaus e
every panel has its own pin assignment, so we do not provide a standard cable; ple ase fin d
a local cable manufacture to make cables.
LCD Installation Guide:
1. Preparing the LV-675, LCD panel and the backlight inverter.
2. Please check the datasheet of the panel to see the voltage of the panel, and set the
jumper JVLCD to +5V or +3.3V.
3. You would need a LVDS type cable.

-o 2E 87
-o 2E 29
-o 2E 40 ;enale GPIO function
-o 2E 07
-o 2E 07 ;enable GPIO configuration
-o 2E F0
-o 2F xx ;set GPIO as input/output; set ‘1’ for input,’0’for output
-o 2E F1
-o 2F xx ;if set GPIO’s as output,in this register its value can be set
Optional :
-o 2E F2
-o 2F xx ; Data inversion register ; ‘1’ inverts the current valus of the
bits ,’0’ leaves them as they are
-o 2E 30
