(2) as insert-ready, fully functional OEM display boards, which can be embedded directly into the user’s peripheral hardware design.

Implementation of an OEM-able subassembly as the "core" of a specific function or interface allows you to focus on the development of customer specific circuitry without having to worry about standard functions and interface circuitry.

Production-ready Board Support Packages (BSPs) and Design

Services for our hardware will further reduce your development time and risk and allow you to focus on your product expertise. Take advantage of PHYTEC products to shorten time-to-market, reduce development costs, and avoid substantial design issues and risks. With this new innovative full system solution you will be able to bring your new ideas to market in the most timely and cost-efficient manner.

Introduction

1 Introduction

The display adapters LCD-014-x and LCD-017-x belong to a series of add-on modules for PHYTEC’s Single Board Computers. These addon modules allow easy development of complex applications with offthe-shelf components.

PHYTEC Display Adapters LCD-014-x and LCD-017-x are compatible to the PHYTEC Display-Interface (PDI) which consists of two universal connectors on the PHYTEC Carrier Board. The display data connector (40 pin FCC connector, 0,5mm pitch) combines various interface signals like LVDS, USB, I

2

C, etc. required to hook up a display and a touch screen. The display power connector (AMP microMatch 8-188275-2) provides all supply voltages needed to supply the display and a backlight.

Because of featuring the PDI the PHYTEC Display Adapters

LCD-014-x and LCD-017-x are interchangeable and the same SBC /

Carrier Board combination might serve for different applications just by changing the adapter board and the software.

Figure 1

depicts the usage of the PHYTEC Display Adapters together

with the modular concept of the phyCARD Development Kit.

The PHYTEC Display Adapters LCD-014-x and LCD-017-x are insert-ready and provide connectivity to displays of different size and resolution, as well as to corresponding touch panels.

Precise specifications for the display populating the display adapter can be found in the applicable datasheet.

Software support for the display adapters is included within the latest

BSPs available for the different phyCARD SBCs.

Minimum Requirements to Operate the Display

Adapters

1.3.1

PDI Power Supply Connector

Operation of the display adapters only requires supply of two input voltages (+3.3V with a 1A load and +5V with a 2A load) and the corresponding GND connections.

These supply pins are located at the PDI power connector X3:

LCD_5V: X3 4, 6, 8

Connect all power input pins to your power supply and all GND pins.

Corresponding GND: X3 1, 3, 5, 7, 9

There are also pins reserved for 12V backlight supply but currently not used.

Caution:

On a custom board we recommend connecting all available +5V input pins and at least the matching number of GND pins to the power supply system.

Please refer to

section 3

for more information.

1.3.2

PDI Data Connector

In order to drive a display at least the LVDS signals, 3V3 logic supply voltage, the /display_enable signal and GND are needed. If the display has touch, then you also need to connect the pins for the touch.

Connectors

2 Connectors

Please note that all connections are not to exceed their expressed maximum voltage or current. Maximum signal input values are indicated in this manual and the corresponding display data sheets. As damage from improper connections varies according to use and application, it is the user's responsibility to take appropriate safety measures to ensure that the module connections are protected from overloading through connected peripherals.

2.1

Carrier Board Connectivity (X5, X3)

The new concept of using display adapters such as the LCD-014-x and

LCD-017-x allows to attach a large number of different displays varying in resolution, signal level, type of the backlight, pinout, etc. to the baseboard using always the same connectors. The new PHYTEC

Display-Interface (PDI) has been designed in order not to limit the range of displays connectable. It consists of two universal connectors which provide the connectivity for the display adapter:

The display data connector combines all needed low-current interface signals.

The display power connector provides all voltages needed to supply the display and the LED backlight.

They also allow easy adaption to customer displays.

2.1.1

Display Data Connector (X5)

The display data connector at X5 (40 pin FCC connector 0,5mm pitch) combines various interface signals like LVDS, USB, I

2

C, etc. required to hook up a display, or a front panel, as well as the low-current supply voltage for the logic on the adapter board.

Touch Screen Connectivity (X1, X16, X17, X18)

LCD-014 only has X1 for connecting the display’s touch. LCD-017 also has X16, X17 and X18 due to the fact, that every touch needs a different type of connector.

2.4

Backlight Connectivity (X4, X10, X11)

LCD-014 only has X4 for connecting the display’s backlight. LCD-

017 also has X10 and X11 because of different cable lengths of the different displays.

Power

3 Power

The display adapters operate off two supply voltages +3.3V and +5V.

They are already prepared for using a third supply voltage +12V up to

+24V for driving more powerful backlights.

Low-current +3.3V fed through the Display Data Connector X5 is intended for supplying the photo sensor, EEPROMs, etc. It should not be used to supply a display or backlight. Only in case of connecting low-current displays, it might be possible to renounce the Display

Power Connector. A green LED indicates power presence.

+3.3V with a 1A load will be fed through the Display Power

Connector X3. It supplies the display and the backlight converter. A green LED indicates power presence.

+5V with a 2A load will also be fed through the Display Power

Connector X3. It will be converted to the power needed for the backlight. A green LED indicates power presence.

Caution:

For maximum EMI performance we recommend as a general design rule to connect all GND pins to a solid ground plane.

Mounting to the phyBASE

The Display Adapters on the phyBASE

The phyBASE Carrier Board provides a flexible development platform enabling quick and easy start-up and subsequent programming of the PHYTEC Extension Boards. The Carrier Board is compatible with all phyCARDs and its design allows easy connection of up to two extension boards as well as the display adapters. This supports a fast and convenient prototyping and software evaluation.

Note:

Only features of the phyBASE which are needed to support the functioning of the display adapters are described. Jumper settings and configurations which are not relevant for the use of the display adapters are not described in the following chapters.

7.1

Controlling Touch with the phyBASE

Two touch screen controllers are available on the phyCARD Carrier

Board. The choice which controller is chosen to handle the signals from the touch screen is pegged to the audio standard supported by the phyCARD. phyCARDs supporting the AC'97 standard use the Wolfson

WM9712L at U1. Its dual functionality for audio and touch AC97 codec allows connecting 4- and 5-wire touch panels. The touch screen data is then available at the AC'97 interface. phyCARDs delivering HDA compliant audio signals use the Cirrus

Logic HDA Audio CODEC at U17 together with the STMPE811 touch panel controller at U28, which is suitable for 4-wire touch panels only. The touch screen data is then available at the I²C interface.

Switches 1 and 2 of DIP-Switch S3 select which controller is used to process the touch panel signals. The different configurations are

shown in

Table 7

Photo Sensor

Mounting to the phyBASE

The Light sensor Analog Input extends to an A/D converter which is connected to the I

2

C bus at address 0xC8 (write) and 0xC9 (read).

7.3

Power Connector

The LED dimmer is connected to the I

2

C bus at address 0xC0 (write) and 0xC1 (read) by default. Alternatively jumper J2 allows to select

0xC2 (write) and 0xC3 (read).

In order to make 12V available for backlight, jumper JP2 must be closed.

Caution:

There is no protective circuitry for the 12V of the backlight! Close jumper JP2 only if the power supply connected to X28 of the phyBASE will not deliver more than 12V!

Mounting to the phyBASE

Mounting a Display Adapter on a Baseboard

An integral hinge is used in order to join baseboard and display adapter together mechanically. It is part of the display adapter and already mounted on it with two screws and an aluminum slat.

Fastening the integral hinge to the baseboard will be done the same way. Therefore PHYTEC ships the display adapter together with a separate aluminum slat and the baseboard comes with the needed screws. To be able to fold display adapter and baseboard together and to put this kit on a table in a stable manner, four plastic spacer bolts, four rubber plugs and two nuts also belong to the baseboard.

Figure 8: Preparing Baseboard and Display Adapter

Do the following steps:

Lay down the aluminum slat on the table.

Put the display adapter beside it so that the holes of its integral hinge match the holes of the aluminum slat.

Position the baseboard so that its corresponding two holes also match and that its corresponding border will be flush with the

aluminum slat as shown in Figure 8. It might be necessary to

flip the aluminum slat in order to achieve this.

Figure 9:

Screwing

Put one screw through the wide opening of one plastic spacer bolt and screw it through the first hole of baseboard and integral hinge into the aluminum slat.

Do the same with a second screw and the second hole.

The remaining screws and plastic spacer bolts are to be mounted on the opposite side of the baseboard. Use the nuts for

that as shown in Figure 9.

Figure 10:

Rubber Plugs and Wires

Stuff the rubber plugs into the plastic spacer bolts.

Insert the ribbon cable into the ZIF socket and lock the socket.

Clip the connector of the second ribbon cable into the socket.
