Object creation

To use TouchLib in your project, you need to create a TouchLib object. This object contains all the sensors that you want to use with TouchLib as well as all related parameters and functions. Note that creating multiple TouchLib objects in one project is not supported; instead it is better to add the sensors to the existing object.

Creating a TouchLib object is easy:

TLSensors<N_SENSORS, N_MEASUREMENTS_PER_SENSOR> tlSensors;

Here, N_SENSORS is the number of sensors you want to use and N_MEASUREMENTS_PER_SENSOR is the number of measurements TouchLib should take to create one sample.

A larger value of N_MEASUREMENTS_PER_SENSOR allows for more noise reduction and better spreading of interfering signals (see scanOrder in General Properties) but also takes more time. Typical values of N_MEASUREMENTS_PER_SENSOR are 8 or 16.
