The Cap Touch 5 Click Board™ features the CY8CMBR3106S-LQXI CapSense® Express™ controller which has an advanced analogue sensing channel and the Capacitive Sigma Delta PLUS (CSD PLUS) sensing algorithm, which delivers a signal-to-noise ratio (SNR) of greater than 100:1 to ensure touch accuracy even in extremely noisy environments. This controller is enabled with Cypress's SmartSense™ Auto-tuning algorithm, which compensates for manufacturing variations and dynamically monitors and maintains optimal sensor performance in all environmental conditions. In addition, SmartSense Auto-tuning enables a faster time-to-market by eliminating the time-consuming manual tuning efforts during development and production ramp-up.
Advanced features, such as LED brightness control, proximity sensing, and system diagnostics, save development time. These controllers enable robust liquid-tolerant designs by eliminating false touches due to mist, water droplets, or streaming water. The CapSense controller locks up the user interface in firmware to prevent touch inputs in streaming water.
Additionally, it implements the advanced noise immunity algorithm, EMC, for stable operation in extremely noisy conditions. Besides that, it is also perfectly suited for low-power applications, such as those operated by a battery, when a capacitive sensing controller that has ultra-low average power consumption have to be selected. The CY8CMBR3106S-LQXI controller draws an average current of 22 µA per sensor.
The Cap Touch 5 Click Board™ supports four CapSense buttons. Its sensitivity can be specified individually for each CapSense button and slider. Higher sensitivity values can be used for thick overlays or small button diameters, while lower sensitivity values should be used for large buttons or thin overlays to minimize power consumption. Therefore, this Click board™ comes without the overlay, so it is up to the user to choose the desired application and implementation.

The demo can run on all the main MikroElektronika development boards.
The library covers all the necessary functions to control the Cap Touch 5 Click Board™.
void captouch5_config_sensors( uint16_t sens_data ) - Function for configuring sensor.void captouch5_config_slider( uint8_t slider_data ) - Function for configuring slider.void captouch5_read_button_status( T_CAPTOUCH5_BUTTONS *buttons ) - Function read button status.The application is composed of three sections :
void applicationTask( )
{
uint16_t temp_byte;
uint16_t last_temp;
uint8_t error_data;
uint8_t temp_slider;
state_check = 0;
error_data = captouch5_process( );
if ( error_data == CAPTOUCH5_ERROR )
{
mikrobus_logWrite( "***** ERROR *****", _LOG_LINE );
mikrobus_logWrite( " ", _LOG_LINE );
mikrobus_logWrite( " ", _LOG_LINE );
state_check = 1;
return;
}
temp_byte = captouch5_read_slider_position( );
captouch5_read_button_status( &buttons );
if ( temp_byte != last_temp )
{
mikrobus_logWrite( "Slider position value: ", _LOG_TEXT );
WordToStr( temp_byte, demo_text );

}
}

Note :
The full application code, and ready to use projects can be found on our LibStock page.
Other mikroE Libraries used in the example:
Depending on the development board you are using, you may need a USB UART click, USB UART 2 click or RS232 click to connect to your PC, for development systems with no UART to USB interface available on the board. The terminal available in all MikroElektronika compilers, or any other terminal application of your choice, can be used to read the message.
This Click board™ is supported with mikroSDK - MikroElektronika Software Development Kit. To ensure proper operation of mikroSDK compliant Click board™ demo applications, mikroSDK should be downloaded from the LibStock and installed for the compiler you are using.
