2.7 Connecting and calibrating a display
One of the ways to interact with the board is via an external display (with or without touchscreen
component). If you want to use a display for video output from the LIME board the best way is to
use the LCD_CON row of pins. The step between the pins of the connector is the smaller one – only
0.05'' (compared to 0.1'' of bigger boards).
Newer displays made by Olimex have both 0.1'' and 0.05'' step connectors. Going for an LCD
output you would also need need and a cable to attach the display to the board. The cable is sold
separately.
The cable used for connection depends on the specific board you are using and more specifically it
depends on the pitch of the LCD connector of the board. We have two cables – both 40-pins ones
but one for the bigger pitch (0.1'') and the other for the smaller one (0.05''). Each of the displays
listed in the table further below has two connectors suitable for both cables:
CABLE-IDC40-6cm – 6cm long cable suitable for 0.1'' step connectors – Product page
CABLE-40-40-10CM – 10cm long cable suitable for 0.05'' step connectors – Product page

2.7.1 Android calibration
Calibrating a display under Android is pretty straightforward from the Android application.
Important: initially the boards are calibrated for a specific display and resolution. If you re-write the
image (no matter whether the SD card or the NAND memory) you might need to use a mouse to
calibrate the display initially. It might be impossible to calibrate it via touching the display.
