Signal Realy Click

Signal 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.

Example Description

Demo application is used to shows basic controls Signal Relay Click.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.SignalRealy

Example Key Functions

• signalrelay_cfg_setup Config Object Initialization function.

void signalrelay_cfg_setup ( signalrelay_cfg_t *cfg );

• signalrelay_init Initialization function.

err_t signalrelay_init ( signalrelay_t *ctx, signalrelay_cfg_t *cfg );

• signalrelay_default_cfg Click Default Configuration function.

void signalrelay_default_cfg ( signalrelay_t *ctx );

• signalrelay_relay_state Relays state.

void signalrelay_relay_state ( signalrelay_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;
    signalrelay_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.

    signalrelay_cfg_setup( &cfg );
    SIGNALRELAY_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    signalrelay_init( &signalrelay, &cfg );

    signalrelay_default_cfg ( &signalrelay );
}

Application Task

Alternately sets relays to ON-OFF state...

void application_task ( void )
{
    uint8_t cnt;

    //  Task implementation.

    for ( cnt = 1; cnt <= 4; cnt++ )
    {
        log_info( &logger, " *** Relay [ %d ] ON ", cnt );
        signalrelay_relay_state( &signalrelay, cnt, SIGNALRELAY_STATE_ON );
        Delay_ms ( 200 );
        log_info( &logger, " *** Relay [ %d ] OFF ", cnt );
        signalrelay_relay_state( &signalrelay, cnt, SIGNALRELAY_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.
