4. Capacitive Multi-Touch Adapter

4.1. Features

The Capacitive Multi-Touch Adapter allows you to connect the Display 10” or Display 7” to

different Toradex Carrier Boards, so that the setup of a system with capacitive multi-touch

and display can be made very easily. Connecting a Display 10” or Display 7” see [3] or [5].

To connect a Carrier Board see [7], [8], [9], and [10].

Please note: It is not possible to connect a Display 7” and Display 10” at the same time.




4.2. Block Diagram

The Capacitive Multi-Touch Adapter has a size of 100 x 60 mm and contains the following

functionalities:

LVDS converter for

the Fusion 10 LCD

interface (RGB/LVDS).

Level Shifter for

the Fusion 10

communication

interface (I2C Level).

Driver for the

Fusion 7 back light

(BL Driver).

Power switches for

the display’s power

and back lights (DISP

Switches).

For more detail

information see [11],

[12], and [13].

5. Setting up a System

To setup a system with a Capacitive Multi-Touch Display kit includes the following steps:

Make the hardware setup (see chapter 5.1 and 5.2)

Choose the kind of Touch-Display

5.1. Choose the Display

Choose either the


or


and connect it to the


It is not possible to connect and use a Display 7” and Display 10” at the same time. See [3]

and [5].

5.2. Choose the Carrier Board

Choose one of the following Carrier Board:

Iris Carrier Board

Colibri Evaluation Board

Ixora Carrier Board

Apalis Evaluation Board

and connect it to the:


See [7],[8],[9] and [10]

5.3. Setup Capacitive Single Touch Drivers

After the wiring is done (see chapter 5.1 and 5.2), choose one of the following Colibri

module and Windows:

Module Win CE5 Win CE6 Win CE 7

Colibri PXA270 ok Ok ok



Colibri T20 ok Ok ok

Contrary to the Multi-Touch Solution, the whole setup for a Single Touch Driver [1] is made

in one package. For this reason every combination of display, carrier board and module has

its own prepared package:

‘Display 7", Iris Carrier Board, Colibri PXA270‘ ‘Display 7", Iris Carrier Board, Colibri PXA300‘ ‘Display 7", Iris Carrier Board, Colibri PXA320‘ ‘Display 7", Iris Carrier Board, Colibri T20‘ ‘Display 10", Iris Carrier Board, Colibri PXA270‘ ‘Display 10", Iris Carrier Board, Colibri PXA300‘




‘Display 10", Iris Carrier Board, Colibri PXA320‘ ‘Display 10", Iris Carrier Board, Colibri T20‘ ‘Display 7", Colibri Evaluation Board, Colibri PXA270‘ ‘Display 7", Colibri Evaluation Board, Colibri PXA300‘ ‘Display 7", Colibri Evaluation Board, Colibri PXA320‘ ‘Display 7", Colibri Evaluation Board, Colibri T20‘ ‘Display 10", Colibri Evaluation Board, Colibri PXA270‘ ‘Display 10", Colibri Evaluation Board, Colibri PXA300‘ ‘Display 10", Colibri Evaluation Board, Colibri PXA320‘ ‘Display 10", Colibri Evaluation Board, Colibri T20‘

All these packages can be found and downloaded at


(see “Single Touch Drivers”)

For a detailed description about to install a Singel Touch Driver, see [14].

5.4. Setup the Capacitive Multi-Touch Solution

After the wiring is done (see chapter 5.1 and 5.2), choose one of the following Colibri

module and Windows:

Module Win CE5 Win CE6 Win CE 7

Colibri T20 --- --- ok

Colibri T30 --- --- ok

Colibri Apalis T30 --- --- ok

Again, contrary to the Single Touch Driver, the setup for the Multi-Touch Solution [2] is

made using different package for the display, the carrier board and the package for the

Unified Multi-Touch Driver.

5.4.1 Install the Unified Multi-Touch Driver

The Unified Multi-Touch Driver is not dependent on the used module, carrier boards, and

windows version and hence, must be installed once using the prepared packages.

This packages can be found and downloaded at


(see “Unified Multi-Touch Driver”)

For a detailed description on how to install the Unified Multi-Touch Driver see [15].






5.4.2 Setup the Display

The setup of the Display is independent of the used module and Windows version (see table

in chapter 5.4). The setup depends on the used display and orientation.

The two displays with two orientations are supported with the following packages:

‘Display 7”, T20, T30, 0’ ‘Display 7”, T20, T30, 180’ ‘Display 10”, T20, T30, 0’ ‘Display 10”, T20, T30, 180’



(see “Display Setting”)

A detailed description about wiring, and setting up a display can be found at [3], and [5].

5.4.3 Installing the Multi-Touch Hardware Adaption Fusion

Each Toradex Carrier Board comes with a prepared package:

‘Iris Carrier Board ‘ ’Colibri Evaluation Board’ ‘Ixora Carrier Board ‘ ’Apalis Evaluation Board’



(see “Carrier Boards”)

A detailed description about wiring and setting up a Carrier Board can be found at [7], [8],

[9], and [10].






6. Bringing up the Touch Panel

After the Hardware connection is setup (see chapter 5.1 and 5.2), the following steps and

tools help to bring up the device:

Install the Display settings and restart the module. The Display should show the

Windows desktop without any border, flicker etc. More details are described in [3]

and [5].

Control the wiring of the Reset and Interrupt lines.

o With the help of the GPIO Config Tool, the chosen SODIMM or MXM3 pin for

the Interrupt can be monitored and the Reset pin can be set to high and low.

(see http://developer.toradex.com/knowledge-base/gpioconfig) .

Control the wiring of the I2C Bus (SDA, SCL signals).

o Run the tool to scan the I2C addresses (I2cAdrScan.exe) which is part of the

packages for the Carrier Boards.

The tool shows the I2C addresses of all devices on the I2C bus. One of these

addresses should be the address of the touch controller.

(Please note that the shown addresses are the addresses of the devices on the

I2C bus and not the address set in the registry.)

o Please check that the Reset pin is low so that the touch controller of the

Display can run.

Install the Unified Multi-Touch Driver and control, if the driver is loaded at startup of

the module. More details are described in [15].

Install the Hardware Adaption Fusion application and control, if the program is

loaded at startup of the module. More details are described in [16].

Check if the touch panel is working.
