@par Example Description

This firmware is a basic example on how to use the STMTouch driver with 1 linear
sensor. The ECS and DTO are also used.

Observed behaviour:

- The LD4 lit each time the linear is touched.
- The LD3 blink frequency follow the linear sensor position when touched.

- The ECS is ON when no touch is detected (all sensors are in the RELEASE state).
  The ECS is always present but its behavior can be modified using some parameters in
  the tsl_conf.h file.

- You can experiment the DTO by touching a sensor for few seconds. The RELEASE state
  is automatically entered and a re-calibration is performed after the timeout is reached.
  This timeout is programmable by the TSLPRM_DTO parameter in the tsl_conf.h file.

@par Hardware and Software environment

  - This example runs on  STM32L052xx, STM32L053xx STM32L062xx and 
    STM32L063xx device lines RevZ.
    
  - This example has been tested with STM32L0538-DISCO board. It can be
    easily tailored to any other devices that embed the TSC peripheral and to
    any other development board supporting touchsensing sensor.


@par How to use it ? 

In order to make the program work, you must do the following:
 - Open your preferred toolchain 
 - Rebuild all files and load your image into target memory
 - Run the example
