Because we offer a source code example of the “Multi-Touch Hardware Adaption", a customer can easily adapt this example to another “Multi-Touch Device".

The main advantage of this concept is that the whole communication to the “Multi-Touch Device" is implemented as an application. The main job of the “ Multi-Touch Hardware Adaption" is to read statuses and touch positions from the “Multi-Touch Device" and send it to the “ Unified Multi-Touch Driver". It communicates with the " Multi-Touch Device" with or without using the standard Toradex Libraries. The “ Multi-Touch Hardware Adaption" runs as an application. As opposed to most of the other drivers, the “Unified Multi-Touch Driver" makes no hardware access to the " Multi-Touch Device" and any other hardware. The “ Unified Multi-Touch Driver" itself is part of the Kernel.

The " Multi-Touch Hardware Adaption" communicates with Unified Multi-Touch Driver with the help of I/O control codes (IOCTLs).

The " Multi-Touch Hardware Adaption" implemented as an application.

The " Unified Multi-Touch Driver" implemented as a driver.

The key components of the “Capacitive Multi-Touch Solution" are shown in the figure above: With the concept of the Capacitive Multi-Touch Solution, it is much easier to develop new Multi-Touch Driver. The time required to develop a driver includes taking out a lot of time for debugging (frequently downloading images, etc.) too.

To adapt the Multi-Touch driver to a new touch controller one needs to have a deep knowledge about Windows CE and the structure of the stream drivers, the use of the Platform builder etc. It includes implementation of the corresponding communication method (I2C, SPI, etc.), read of the status and touch positions out of the controller and transform it according to the CETOUCHINPUT structure. To adapt a “standard" Multi-Touch driver to a specific capacitive multi-touch controller, the PDD layer must be modified. Therefore, Toradex has developed an architecture, which we call, Capacitive Multi-Touch Solution to easily adapt our capacitive multi-touch driver to any particular touch hardware. The communication protocols of these devices are not standardized, so Toradex is not able to offer a capacitive touch driver that runs out-of-the-box with its Board Support Packages.

Toradex Capacitive Multi-Touch Solution Ĭapacitive touch devices usually feature an I2C interface, while the other type of devices come with an SPI interface. Multi-Touch solution also requires extra implementation in the application itself. At the moment, we support only the standard gestures like PAN, SCROLL, SELECT, DOUBLESELECT, and HOLD. With another gesture recognizer (plug-in) additional gesture like ZOOM, ROTATE are possible. The standard gesture recognizer supports PAN, SCROLL, SELECT, DOUBLESELECT, and HOLD.

Compact 7 Multi-Touch Driver and Gesture.

Windows Embedded Compact 7/2013 offers a new advanced type of support for multi-touch and gesture on specialized devices. Multi-Touch Support implemented in WinCE The capacitive Single-Touch and Multi-Touch drivers will not be used for new projects. In the future, all capacitive touch drivers will be based on the Touch Solution. The Multi-Touch Solution from Toradex gives the customer the possibility to write and maintain their own touch driver with little effort. In the past, Toradex created custom capacitive Touch Drivers (single- or multi-touch) for specific devices and certain OS versions.īecause there were no defined standards to connect capacitive touch devices, this resulted in having a variety of touch drivers.
