Click library

  • Author : Mihajlo Djordjevic
  • Date : Dec 2019.
  • Type : GPIO type

Software Support

We provide a library for the Comparator 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 Comparator Click driver.

Standard key functions :

  • Config Object Initialization function.

    void comparator_cfg_setup ( comparator_cfg_t *cfg );

  • Initialization function.

    COMPARATOR_RETVAL comparator_init ( comparator_t ctx, comparator_cfg_t cfg );

  • Click Default Configuration function.

    void comparator_default_cfg ( comparator_t *ctx );

Example key functions :

  • This function check and return state of the o1 ( AN ) pin of Comparator Click Board.

    uint8_t comparator_check_output_one ( comparator_t *ctx );

  • This function check and return state of the o2 ( INT ) pin of Comparator Click Board.

    uint8_t comparator_check_output_two ( comparator_t *ctx );

Examples Description

This is an example which demonstrates the usage of Comparator Click board.

The demo application is composed of two sections :

Application Init

Application Init performs Logger and Click initialization.


void application_init ( void )
{
    log_cfg_t log_cfg;
    comparator_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_printf( &logger, "--------------------------\r\n" );
    log_printf( &logger, "     Application  Init\r\n" );
    Delay_ms ( 500 );

    //  Click initialization.

    comparator_cfg_setup( &cfg );
    COMPARATOR_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    comparator_init( &comparator, &cfg );

    log_printf( &logger, "--------------------------\r\n" );
    log_printf( &logger, " --- Comparator Click --- \r\n" );
    log_printf( &logger, "--------------------------\r\n" );
    Delay_ms ( 1000 );

    log_printf( &logger, " -- Initialization done --\r\n" );
    log_printf( &logger, "--------------------------\r\n" );
    Delay_ms ( 1000 );
}

Application Task

Comparator Click checks state of the O1 and O2 pins. Results are being sent to the UART Terminal where you can track their changes. All data logs write on USB UART and changes for every 1 sec.


void application_task ( void )
{
    out_state_one = comparator_check_output_one( &comparator );
    out_state_two = comparator_check_output_two( &comparator );

    log_printf( &logger, "   Output One: \r\n" );

    if ( out_state_one )
    {
        log_printf( &logger, "   High \r\n" );
    }
    else
    {
        log_printf( &logger, "   Low \r\n" );
    }

    Delay_ms ( 500 );

    log_printf( &logger, "   Output Two: \r\n" );

    if ( out_state_two )
    {
        log_printf( &logger, "   High \r\n" );
    }
    else
    {
        log_printf( &logger, "   Low \r\n" );
    }

    Delay_ms ( 500 );

    log_printf( &logger, "--------------------------\r\n" );
    Delay_ms ( 1000 );
}  

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.Comparator

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.

Clock Gen 4 Click

0

Clock Gen 4 Click is a compact add-on board that contains both a clock generator and a multiplier/jitter reduced clock frequency synthesizer. This board features the CS2200-CP, an analog PLL architecture comprised of a Delta-Sigma fractional-N frequency synthesizer from Cirrus Logic. This clocking device utilizes a programmable phase lock loop and allows frequency synthesis and clock generation from a stable reference clock. It generates a low-jitter PLL clock from an external crystal, supports both I²C and SPI for full software control, and also has configurable auxiliary clock output. This Click board™ is suitable for MCU clock source, or in applications like digital effects processors, digital mixing consoles, and many more.
