Relay 3 Click

Relay 3 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.

• Type : GPIO type

Software Support

Example Description

This example starts off with the initialization and configuration of the Click and logger modules and later on showcases how to turn specified relays ON/OFF using the output pins.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.Relay3

Example Key Functions

• relay3_cfg_setup Config Object Initialization function.

void relay3_cfg_setup ( relay3_cfg_t *cfg );

• relay3_init Initialization function.

err_t relay3_init ( relay3_t *ctx, relay3_cfg_t *cfg );

• relay3_relay_on This function turns on either the 1st or the 2nd relay on the Click.

void relay3_relay_on ( uint8_t relay );

• `` This function turns off either the 1st or the 2nd relay on the Click.

relay3_relay_off  ( uint8_t relay );

Application Init

This function initialises and configures the logger and Click modules.

void application_init ( )
{
    log_cfg_t log_cfg;
    relay3_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.

    relay3_cfg_setup( &cfg );
    RELAY3_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    relay3_init( &relay3, &cfg );
}

Application Task

This function turns on the 1st and the 2nd relay and then turns them both off.

void application_task ( )
{
    case_1( );
    Delay_ms ( 1000 );

    case_2( );
    Delay_ms ( 1000 );

    case_3( );
    Delay_ms ( 1000 );
}

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.
