This page describes the parameters currently available in the Touch Sensor Module Firmware 1.55 and Neonode Touch Sensor Module Firmware 2.0 (NTSMF 2.0-BETA), except for ). The parameter "Scanning Range which " is only available in from NTSMF 2.0 -BETA through zForce Programmer.
The parameters described in this document can be adjusted by changing the Touch Sensor Modules configuration. These parameters can be configured using Neonode Workbench, an application using zForce SDK, Arduino Library (I2C) or zForce Programmer. The parameters that have been configured using either Neonode Workbench, zForce SDK or Arduino Library, are stored in the RAM memory, meaning that the new configuration will have to be re-applied after each reboot. If the parameters are instead configured using zForce Programmer, the parameters will not have to be re-applied after each reboot.

Scanning Range defines the Scanning Area of the sensor. For the definition of Scanning Area, refer to TSM - Definitions. This setting can only be changed through the zForceProgrammer. The Scanning Range can beset to a lower ((shorter range) value. It can also be set to a higher value than the default if the TSM FirmWare (FW) allows Extended or Maximum Range in Y-axis. As default the Scanning Range is set to a DefaultRange, see for the values.he Mechanical Data, Table 1for the values.

Touch Active Area Adjustments

When the snapping filter is enabled, an outer- and inner distance to the edge of the scanning area can be configured. It can be configured for the left, right, top and bottom edge of the scanning area with the unit of 10-1 mm. When a touch is detected between the inner- and outer distance regions, the reported touch location is snapped to the edge of the configured touch area.
Click On Touch
...
The filter is designed to prevent multiple touches within a defined area for a short period of time. Both the prevention radius (10-1 mm) and the prevention time (ms) are configurable parameters.
When enabled the system will define a prevention area for each touch and will not react to additional touches in those areas until the prevention time has expired. This way undesired double-clicks can be prevented for a certain area while maintaining quick response times outside of the prevention areas on the TAA.
