SwipeSwitch Click is capacitive touch, gesture, and proximity sensing Click board™, which is equipped with the IQS266, an integrated trackpad controller circuit which features ProxSense® and IQ Switch® technologies. This IC consists of a 2x3-channel capacitive trackpad controller, and a single self-capacitive proximity sensor, which can be used to wake up the device. This ensures very low power consumption, as the device is able to stay in the Sleep mode when not used. The IQS266 can detect a number of various configurable swipe and tap gestures. An Automatic Tuning Implementation (ATI) feature ensures an optimized performance in various conditions.

Click library

  • Author : MikroE Team
  • Date : Dec 2019.
  • Type : I2C type

Software Support

We provide a library for the SwipeSwitch Click as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.

Package can be downloaded/installed directly form compilers IDE(recommended way), or downloaded from our LibStock, or found on mikroE github account.

Library Description

This library contains API for SwipeSwitch Click driver.

Standard key functions :

  • Config Object Initialization function.

    void swipeswitch_cfg_setup ( swipeswitch_cfg_t *cfg );

  • Initialization function.

    SWIPESWITCH_RETVAL swipeswitch_init ( swipeswitch_t ctx, swipeswitch_cfg_t cfg );

Example key functions :

  • This function reads Gestures

    uint8_t swipeswitch_read_gestures ( swipeswitch_t *ctx );

  • This function reads X coordinate.

    uint8_t swipeswitch_read_x_coordinate ( swipeswitch_t *ctx );

  • This function reads Y coordinate.

    uint8_t swipeswitch_read_y_coordinate ( swipeswitch_t *ctx );

Examples Description

Click board is able to sense several different swipe gestures.

The demo application is composed of two sections :

Application Init

Initialization and configuration of the chip for measurement.


void application_init ( void )
{
    log_cfg_t log_cfg;
    swipeswitch_cfg_t cfg;

    /** 
     * Logger initialization.
     * Default baud rate: 115200
     * Default log level: LOG_LEVEL_DEBUG
     * @note If USB_UART_RX and USB_UART_TX 
     * are defined as HAL_PIN_NC, you will 
     * need to define them manually for log to work. 
     * See @b LOG_MAP_USB_UART macro definition for detailed explanation.
     */
    LOG_MAP_USB_UART( log_cfg );
    log_init( &logger, &log_cfg );
    log_info( &logger, "---- Application Init ----" );

    //  Click initialization.

    swipeswitch_cfg_setup( &cfg );
    SWIPESWITCH_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    swipeswitch_init( &swipeswitch, &cfg );
    Delay_ms ( 300 );

    display_mode = SWIPESWITCH_GESTURE_MODE;

    if ( display_mode == SWIPESWITCH_GESTURE_MODE)
    {
        log_printf( &logger, "<<< GESTURE MODE >>> \r\n" ); 
    }
    else if ( display_mode == SWIPESWITCH_POSITION_MODE)
    {
        log_printf( &logger, "<<< POSITION MODE >>> \r\n" ); 
    }
}

Application Task

Display message on a terminal when new event occurs ( TAP or SWIPE ) along with the X and Y coordinates depending on the display_mode value.


void application_task ( void )
{
    if ( display_mode == SWIPESWITCH_GESTURE_MODE)
    {
        events = swipeswitch_read_events( &swipeswitch );
        gestures = swipeswitch_read_gestures( &swipeswitch );


        if ( ( events & ( SWIPESWITCH_EVENT_SWIPE ) ) != 0 )
        {
            if ( ( gestures & SWIPESWITCH_GESTURE_SWIPE_UP ) != 0 )
            {
                log_printf( &logger, "SWIPE UP \r\n" );
            }
            if ( ( gestures & SWIPESWITCH_GESTURE_SWIPE_DOWN ) != 0 )
            {
                log_printf( &logger, "SWIPE DOWN \r\n" );
            }
            if ( ( gestures & SWIPESWITCH_GESTURE_SWIPE_LEFT ) != 0 )
            {
                log_printf( &logger, "SWIPE LEFT \r\n" );
            }
            if ( ( gestures & SWIPESWITCH_GESTURE_SWIPE_RIGHT ) != 0 )
            {
                log_printf( &logger, "SWIPE RIGHT \r\n" );
            }
        }

        else if ( ( events & ( SWIPESWITCH_EVENT_TAP ) ) != 0 )
        {
            log_printf( &logger,"TAP \r\n" );
        }
    }
    else if ( display_mode == SWIPESWITCH_POSITION_MODE)
    {
        x_coordinate = swipeswitch_read_x_coordinate( &swipeswitch );
        y_coordinate = swipeswitch_read_y_coordinate( &swipeswitch );

        if ( ( x_coordinate != old_x_coordinate) || ( y_coordinate != old_y_coordinate ) )
        {
            log_printf( &logger,"Coordinate : (%u , %u)\r\n", (uint16_t) x_coordinate, (uint16_t) y_coordinate );

            old_x_coordinate = x_coordinate;
            old_y_coordinate = y_coordinate;
        }
    }
    Delay_ms ( 300 );
}

The full application code, and ready to use projects can be installed directly form compilers IDE(recommneded) or found on LibStock page or mikroE GitHub accaunt.

Other mikroE Libraries used in the example:

  • MikroSDK.Board
  • MikroSDK.Log
  • Click.SwipeSwitch

Additional notes and informations

Depending on the development board you are using, you may need 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.

Current 7 Click is a compact add-on board providing a precise and accurate current sensing solution. This board features the INA282, a wide common-mode range, bidirectional, high-accuracy current shunt monitor from Texas Instruments. The INA282 represents a voltage output current shunt monitor that can sense drops across shunts at common-mode voltages from –14 V to +80 V, independent of the supply voltage, which operates in a range from 2.7V up to 18V supply. The zero-drift topology enables high-precision measurements with maximum input offset voltages as low as 70μV. Also, the user is allowed to process the output signal in analog or digital form.

RS485 3 click uses SN65HVD31DR from Texas Instruments, a tri-state differential line driver and differential input line receiver. The click is intended to be used as UART to RS422/RS485 communication interface. It is suited for transmitting smaller blocks of data over long distances, using the four-wire bus, allowing for full-duplex communication.
