How Does The Cap Touch 6 Click Board™ Work?
The Cap Touch 6 Click Board™ is based on the IQS227D, a fully integrated single-channel capacitive controller with an internal voltage regular and reference capacitor from Azoteq. As known, the capacitive touch technology works by detecting changes in capacitance on the screen or touchpad, in this case, the sensing area at the top of the frontal side of the board, when a finger or other conductive object comes into contact with it. The IQS227D is built on ProxSense® low voltage platform, ideal for battery application. It comes with dual outputs (touch and proximity outputs don't need to be configured), a low-power mode while sensing proximity, and an advanced on-chip digital signal processing.
Touch and proximity features, alongside its mikroBUS™ pins, marked TOU and POU, only used to communicate with MCU, also have their corresponding LED indicators, labelled Touch and Prox, reporting the activity of these features. If a touch/proximity event is detected on the onboard sensing pad, the state of the corresponding LED will be changed, indicating an activated channel.
In addition to pins of the mikroBUS™ socket, these functions can also be found on the unpopulated header for external uses if they are necessary for the user in some specific application. As mentioned earlier, this board contains a capacitive sensing area that is the only element on the top side of the board, allowing the protective acrylic plexiglass layer placement.
The Cap Touch 6 Click Board™ can operate with either 3.3V or 5V logic voltage levels selected via the VCC SEL jumper on the back side of the board. This way, both 3.3V and 5V capable MCUs can use the communication lines properly. However, the Click board™ comes equipped with a library containing easy-to-use functions and an example code that can be used, as a reference, for further development.

Key functions
-
captouch6_get_tout_pinThis function returns the TOUT pin logic state. -
captouch6_get_pout_pinThis function returns the POUT pin logic state.
Example Description
This example demonstrates using the Cap Touch 6 Click Board™ by reading and displaying the touch and proximity events.
void application_task ( void )
{
static uint8_t old_touch_state = 0, old_prox_state = 0;
uint8_t touch_state = captouch6_get_tout_pin ( &captouch6 );
uint8_t prox_state = captouch6_get_pout_pin ( &captouch6 );
if ( ( old_touch_state != touch_state ) || ( old_prox_state != prox_state ) )
{
log_printf( &logger, " Touch: %srn", ( char * ) ( !touch_state ? "detected" : "idle" ) );
log_printf( &logger, " Proximity: %srnn", ( char * ) ( !prox_state ? "detected" : "idle" ) );
old_touch_state = touch_state;
old_prox_state = prox_state;
}
