Click library

  • Author : MikroE Team
  • Date : dec 2019.
  • Type : GPIO type

Software Support

We provide a library for the CapExtend3 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 CapExtend3 Click driver.

Standard key functions :

  • Config Object Initialization function.

    void capextend3_cfg_setup ( capextend3_cfg_t *cfg );

  • Initialization function.

    CAPEXTEND3_RETVAL capextend3_init ( capextend3_t ctx, capextend3_cfg_t cfg );

Example key functions :

  • Function reads state of AN pin

    uint8_t capextend3_Touch_0 ( capextend3_t *ctx );

  • Function reads state of RST pin

    uint8_t capextend3_Touch_1 ( capextend3_t *ctx );

  • Function reads state of CS pin

    uint8_t capextend3_Touch_2 ( capextend3_t *ctx );

Examples Description

This application features four capacitive sensor pads, that can sense touch through a variety of different materials.

The demo application is composed of two sections :

Application Init

Initialize GPIO Driver

void application_init ( void )
{
    log_cfg_t log_cfg;
    capextend3_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.
    capextend3_cfg_setup( &cfg );
    CAPEXTEND3_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    capextend3_init( &capextend3, &cfg );
}

Application Task

Depending on which button is touched the usb uart will show number of that button.

void application_task ( void )
{
    uint8_t touch_0;
    uint8_t touch_1;
    uint8_t touch_2;
    uint8_t touch_3;
    uint8_t touch_4;

    touch_0 = capextend3_touch_0( &capextend3 );
    touch_1 = capextend3_touch_1( &capextend3 );
    touch_2 = capextend3_touch_2( &capextend3 );
    touch_3 = capextend3_touch_3( &capextend3 );
    touch_4 = capextend3_touch_4( &capextend3 );

    if ( touch_2 == 0 )
    {
       log_printf( &logger, "Active Guard\r\n" ); 
    }
    if ( touch_0 == 0 )
    {
       log_printf( &logger, "Touch 0 \r\n" ); 
    }
    if ( touch_1 == 0 )
    {
       log_printf( &logger, "Touch 1 \r\n" ); 
    }
    if ( touch_3 == 0 )
    {
       log_printf( &logger, "Touch 3 \r\n" ); 
    }
    if ( touch_4 == 0 )
    {
       log_printf( &logger, "Touch 4 \r\n" ); 
    }
    if ( ( touch_0 && touch_1 && touch_2 && touch_3 && touch_4 ) == 0 ) 
    {
        log_printf( &logger, "------------------------\r\n" ); 
    }
    Delay_ms ( 100 );
}

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.CapExtend3

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.

PWR Meter 3 Click - 30A is a compact add-on board that measures voltage and current through the connected load. This board features the ACS37800KMACTR-030B3-I2C, an I2C-configurable power monitoring solution from Allegro MicroSystems, which simplifies the addition of power monitoring to many AC/DC powered systems. The ACS37800KMACLU-090B3-I2C Hall-effect-based current sensing technology achieves reinforced isolation ratings (4800 VRMS) alongside a reliable ±30A bidirectional current sensing. It also has two LED indicators for the realization of visual detection of some anomalies in operation, such as under/overvoltage and fast overcurrent fault detection.
