Slider Click features a mechanical slide action potentiometer - a slider, which gives a nice feeling when actuating, along with 16 SMD LEDs, that can be used for any kind of visual feedback. The onboard high-resolution 22-bit ADC can detect even the smallest move, faithfully capturing the smoothness of the slider movement, while digitizing its position. The 16 onboard SMD LEDs can give a nice visual feedback of the slider position, but those LEDs can also be used for other purposes since they are not hardwired to the slider.

Click library

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

Software Support

We provide a library for the Slider 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 Slider Click driver.

Standard key functions :

  • Config Object Initialization function.

    void slider_cfg_setup ( slider_cfg_t *cfg );

  • Initialization function.

    SLIDER_RETVAL slider_init ( slider_t ctx, slider_cfg_t cfg );

  • Click Default Configuration function.

    void slider_default_cfg ( slider_t *ctx );

Example key functions :

  • Function calls slider_readADC function, but first checks is ADC conversion finished.

    uint32_t slider_read_adc_and_ready ( slider_t *ctx );

  • Function enables LED output to shows output laches when state is low, and disables LED output when state is high.

    void slider_enable_led_output ( slider_t *ctx, uint8_t state );

  • Function enables output laches to monitor converted ADC value, when state is high.

    void slider_enable_output_laches ( slider_t *ctx, uint8_t state );

Examples Description

This example detect even the smallest move, faithfully capturing the smoothness of the slider movement, while digitizing its position.

The demo application is composed of two sections :

Application Init

Initializes Click driver


void application_init ( void )
{
    log_cfg_t log_cfg;
    slider_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.

    slider_cfg_setup( &cfg );
    SLIDER_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    slider_init( &slider, &cfg );
    slider_default_cfg( &slider );
}

Application Task

Converts analog input voltage (VCC), witch value depends on the slider position, to digital output value, shows result of conversion on LED and logs result on USB UART.


void application_task ( void )
{
    adc_value = slider_write_output( &slider );
    log_printf( &logger, "%.0f\r\n", adc_value );
}

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.Slider

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.
