Slider Click

Slider Click demo application is developed using the NECTO Studio, ensuring compatibility with mikroSDK's open-source libraries and tools. Designed for plug-and-play implementation and testing, the demo is fully compatible with all development, starter, and mikromedia boards featuring a mikroBUS™ socket.

Click Library

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

Software Support

Example Description

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

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.Slider

Example Key Functions

• slider_cfg_setup Config Object Initialization function.

void slider_cfg_setup ( slider_cfg_t *cfg );

• slider_init Initialization function.

err_t slider_init ( slider_t *ctx, slider_cfg_t *cfg );

• slider_default_cfg Click Default Configuration function.

void slider_default_cfg ( slider_t *ctx );

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

uint32_t slider_read_adc_and_ready ( slider_t *ctx );

• slider_enable_led_output 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 );

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

void slider_enable_output_laches ( slider_t *ctx, uint8_t state );

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 );
}

Application Output

This Click board can be interfaced and monitored in two ways:

• Application Output - Use the "Application Output" window in Debug mode for real-time data monitoring. Set it up properly by following this tutorial.
• UART Terminal - Monitor data via the UART Terminal using a USB to UART converter. For detailed instructions, check out this tutorial.

Additional Notes and Information

The complete application code and a ready-to-use project are available through the NECTO Studio Package Manager for direct installation in the NECTO Studio. The application code can also be found on the MIKROE GitHub account.
