improve performace.

3.4 Communicating with Sensor

3.4.1 Neonode Workbench

Neonode Workbench is a software tool to use with zForce AIR™ sensors. With Neonode Workbench it is possible to:
• Visualize sensor touches.
• Temporarily configure sensor characteristics, such as active area and scanning frequency.
• View the sensor firmware version.
• Conduct Open/Short-circuit tests to identify any damaged photo or laser diodes.

3.4.2 USB HID Digitizer Mode

The easiest way to see the Touch Sensor functionality is to use USB HID Digitizer mode:
1. When the sensor has enumerated, it will act as a touch screen USB HID device.
2. Put an object in the touch active area, touch HID reports will be send to host.
For more information on USB HID Digitizer mode, refer to

3.4.3 USB HID Raw Mode

In USB HID Raw Mode, communication with a Touch Sensor is performed by sending and receiving messages as
reports defined by the USB HID standard.
To start communicating, perform the following:
1. When the sensor has enumerated, start communicating as defined in
messages are encoded with ASN.1.Refer to
2. The Touch Sensor starts sending touch notifications once it is initialized. For initialization procedures, refer
to Initializing Sensors

3.4.4 I2C Transport

To start communicating, perform the following:
1. Send or read data over the I2C bus. Refer to
1. Refer to Presentation Layer (ASN.1)
2. The sensor starts sending touch notifications once it is initialized. For initialization procedures, refer to
Initializing Sensors

3.4.5 SDK

To start communicating, follow the Getting Started instructions in the separate SDK documentation.
