What's new?
- supports TSI noise mode
- new patented AFID keydetector - connected with the noise mode - noise robust (capable of passing EN 61000-4-6)
- C++ wrapper
AFID + noise mode
The TSS noise mode is available only for Kinetis L. How does it work inside TSS?The capacitive measurement is active RESPONSE TIME-1 number of an execution of TSS_Task. This implies that a noise is measured always once until the decision is made about the electrode status (touch/release). Since the moment, the noise is detected, the noise mode is active until there's no noise on any electrode. Without any noise, TSS switches back to the capacitive measurement.
The example named TWRKXX_DEMO_EMC shows usage of AFID and the noise mode.
C++ wrapper
We added C++ wrapper for entire TSS which simplifies TSS usage. You still have to define system setup header file (that's how TSS was designed, I would like to change this). C++ supports all features which TSS provides.There are 5 controls (as in TSS), one system and the control factory. I don't introduce callback's classes here.
TSS_System is a singleton, which takes care of TSS settings. If you don't want to use any control, system handles everything and you can retrieve informations which are available (like electrode status).
If you want to use controls, take a look at TSS_ControlFactory which facilitates creation of new controls. Doesn't need to be used.
The entire API contain doxygen comments. Open FRDMKLXX_DEMO_CPP example which is located in EXAMPLES folder to see how to create new control and register callback.
