6.10 LCD_CON 40pin connector

The LCD_CON pins are led out on a separate 40pin connecter for the ease of connecting an LCD.

We have tested the ability of the board to interact with such a display. They allow the user to attach

additional hardware, check readings or perform hardware debug.

Important: you need additional 40PIN ribbon cable to connect an Olimex display and the

LCD_CON.

The LCD connector is suitable for a number of Olimex displays and touchscreen panels with

different native resolution – the smallest available is the 4.3'' one called LCD-OLinuXino-4.3TS

with native screen resolution of 480×272, through the 7'' one named LCD-OLinuXino-7TS with

800×480, to the 1024×600 10.1'' LCD-OLinuXino-10TS.

Signals marked with * are multiplexed with either a peripheral device or another connector. Ensure that the multiplexing is handled

properly on software and/or hardware level (else there would probably occur wrong levels, loss of data, etc).

IMPORTANT:

To use Android with display or resolution different than HDMI and 1024×600 (default settings) you

need to upload new Android image to the board. These images are available here:

https://www.olimex.com/wiki/A10-OLinuXino-LIME (using an operating system – NAND flash).

In Debian Linux you would need to start a start a shell script to change the built-in the image

resolution settings. Start it with ./change_display_a10_lime.sh and follow the instructions. Please

refer to chapter 2.5 “Changing the default image resolution” for more information.
