Relay Click

Relay 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 : Katarina Perendic
• Date : okt 2019.
• Type : GPIO type

Software Support

Example Description

Demo application is used to shows basic controls Relay Click

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.Relay

Example Key Functions

• relay_cfg_setup Config Object Initialization function.

void relay_cfg_setup ( relay_cfg_t *cfg );

• relay_init Initialization function.

err_t relay_init ( relay_t *ctx, relay_cfg_t *cfg );

• relay_default_cfg Click Default Configuration function.

void relay_default_cfg ( relay_t *ctx );

• relay_set_state Relay set state.

void relay_set_state ( relay_t *ctx, uint8_t relay, uint8_t state );

Application Init

Configuring Clicks and log objects. Settings the Click in the default configuration.

void application_init ( void )
{
    log_cfg_t log_cfg;
    relay_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.

    relay_cfg_setup( &cfg );
    RELAY_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    relay_init( &relay, &cfg );
    
    relay_default_cfg ( &relay );
    Delay_ms ( 1000 );
    Delay_ms ( 500 );
}

Application Task

Alternately sets relays to ON-OFF state...

void application_task ( void )
{
    uint8_t cnt;
    
    //  Task implementation.
    
    for ( cnt = 1; cnt <= 2; cnt++)
    {
        log_info( &logger, "*** Relay %d state is ON \r\n", cnt);
        relay_set_state( &relay, cnt, RELAY_STATE_ON );
        Delay_ms ( 1000 );
        log_info( &logger, "*** Relay %d state is OFF \r\n", cnt);
        relay_set_state( &relay, cnt, RELAY_STATE_OFF );
        Delay_ms ( 200 );
    }
    
}

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.
