Introduction
About ELI (the Easy LCD Interface)
ELI®is Future Designs, Inc.’s family of long-life, plug-and-play embedded displays. ELI products
are true modular embedded display solutions that require no engineering or lead-time. All ELI
products are compatible with a wide range of single board computers including Raspberry Pi,
BeagleBone Black and Windows-based units. FDI designed ELI as an embedded display option
that requires minimal development time to help customers reach production quickly. Once a
product is in production, FDI’s 10-15 year ELI product availability guarantee helps ensure
production schedules without the risk of expensive or time consuming redesigns. Learn more about
ELI at TeamFDI.com/ELI.
ELI Compatibility
ELI products are compatible with most single board computers, PCs and operating systems. See the
compatibility tab at https://www.teamfdi.com/product-details/eli101-iphw for the results of FDI’s
compatibility tests with popular operating systems and platforms. Our results, as indicated in the
table, demonstrate ELI’s versatility but the table is not exhaustive. ELI products are designed to
work with any single board computer that has an HDMI or DVI output. To submit a question about
ELI’s compatibility with a platform or operating system that is not included in the table, contact a
member of the FDI support team at [email protected].

ESD Warning
Figure 1. Electrostatic Sensitive Device
Our ELI units are shipped in a protective anti-static package. Do not subject the module to high
electrostatic potentials. Exposure to high electrostatic potentials may cause damage to the boards that
will not be covered under warranty. General practice for working with static sensitive devices should
be followed when working with this device.
Determining the Revision of your ELI
All ELI devices have a label placed on the board to identify the part number and revision of the unit.
This label will help you quickly and correctly identify your ELI unit’s part number and revision
number. An example of an ELI label is shown below.

Figure 2. ELI101-IPHW Connectors
Power Details
A 12VDC +/- 5% power supply with a 2.0A output will power any board from the ELI Family. This
allows a common, off-the-shelf power supply such as the T1071-P5P-ND to be used for quick demos
or prototyping across the entire ELI Family. In general, any 12VDC power supply with a 2.1mm
center positive plug will be acceptable if it can provide enough current to power the particular ELI
unit being used. On the ELI101-IPHW plug power into the (P2) connector.
The ELI101-IPHW input power range is expanded to include +5 to 24V DC ± 5% (2.0A) for greater
design flexibility.

For volume production applications, the input power can be optimized for your ELI unit and lower
capacity power supplies can be used.
In cases where the barrel connector is not desired, you can use the alternate power input connector
(J6) which supports directly plugging in 20-26 AWG wire with maximum 5A current per contact. The
datasheet for this J6 connector (PCB terminal block - PTSM 0,5/ 2-2,5-H SMD WH R24 –1814634)
can be found at http://tinyurl.com/1814634.
To verify that the ELI101-IPHW unit is correctly powered you may check the 12VDC input with a
Fluke meter or scope by probing the +12V and GND contacts shown below. Please verify that the
12VDC is present, is within the +/- 5% tolerance and is free from excessive noise or AC ripple.
Note: If using an input that is within the acceptable range of +5VDC to +24VDC (+/- 5%),
please keep in mind that the 12V Test points should be at the voltage of your chosen power
supply (5-24VDC).

Extended Display Information Data (EDID)
ELI uses Extended Display Identification Data (EDID) for automatic configuration with many
operating systems. You can find out more on our website at http://www.teamfdi.com/edid/.
Brightness Control
ELI101-IPHW contains a Brightness Control potentiometer (VR1) on the backside of the board, see
Figure 4. Using this pot, you can set the default “Factory” brightness of the LCD Backlight. Turning
the pot fully clockwise results in maximum brightness of the display. Turning the pot counter-
clockwise will turn the backlight off.
Figure 4. Brightness Control Potentiometer (VR1).
PWM Control of Backlight
ELI provides an input for an external processor to control the brightness of the display backlight, see
Figure 5. Controlling the backlight also controls ELI power consumption (the display backlight is
typically one of the larger sources of power consumption in the system). PWM dimming is an input
with a 0 to 3.3 VDC range and the user should drive this with a push-pull type output or a suitable
open collector output.

Figure 5. Backlight Control
To control the display backlight, the user should connect an externally generated Pulse Width
Modulated (PWM) signal to J3 pin 2 along with a common ground to J3 pin 3. The frequency range
for this signal is from 100Hz to 2KHz. Each ELI’s backlight properties vary, so the user should test
their version for an acceptable range of brightness control. Your 0 to 100% brightness range may be
40% to 90% of the PWM range. In certain installations, a series resistor may be required to ensure a
clean PWM signal to the ELI. The suggested value for the resistor is 100ohms. See Figure 7 below,
for example of connectivity. Actual testing in your installation may require this resistor to be
changed, or possibly not required at all.
On the ELI unit, the PWM dimming signal is pulled up between 1.49V and 0.487 volts. This is
controlled by the Linear Brightness Control Potentiometer (VR1), detailed in Paragraph 10.0.
If you provide NO PWM signal to VLED_PWM (J3 pin 2), ELI will provide 100% backlight power
to the display (default potentiometer setting). The potentiometer setting can be overdriven by the
push-pull PWM input on J3-2, so the external SBC can always maintain control of the backlight
brightness across the full range. The potentiometer can be used to set a default backlight brightness
level that is used until the SBC has time to boot up and set the desired brightness level via PWM
output. This feature can also be used to “blank” the display during boot-up in cases where the default
BIOS settings aren’t compatible with ELI. This prevents the screen from showing incorrect images
until the SBC has time to boot and read EDID or set the correct video timings for the ELI101-IPHW.
The output at pin 1 of J3 is 3.3VDC ± 5%. If the external system is capable of directly driving the
PWM dimming signal at 3.3VDC, there is no need to connect pin 1 to the cable. ELI provides the 3.3
VDC signal for the external system in case this voltage is needed to generate the correct levels on the
PWM VLED_PWM Input.

Figure 7. Raspberry Pi Signal and Ground
The ELI backlight can be controlled from a Raspberry Pi. See Figure 7 for a wiring diagram. Our software
is available on the FDI website at https://www.teamfdi.com/product-details/eli101-iphw#software or you
may copy the code from here:
/* Changes brightness of ELI backlight given a command line argument between 0 and
the set range. Uses bcm2835 header file provided by Broadcom at
http://www.airspayce.com/mikem/bcm2835/bcm2835-1.52.tar.gz This source code must be
compiled using "g++ brightness.cpp -o brightness -l bcm2835"in order to properly
link the header file. Must be run using sudo, accessing GPIO pins requires root
permissions. After compiling, you may add executable to "/usr/bin" which allows you
to type "sudo brightness <value>" to change brightness anywhere in terminal. The
"/boot/config.txt" file must also be changed by adding a "#" before the line
"dtparam=audio=on". This disables audio output from the Raspberry Pi. If this is
not disabled then anytime sound is output the screen will return to 100%
brightness.
