M-BUS RF 2 Click

M-BUS RF 2 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.

• Date : Nov 2023.
• Type : UART type

Software Support

Example Description

This example demonstrates the use of M-BUS RF 2 Click board by processing the incoming data and displaying them on the USB UART.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.MBUSRF2

Example Key Functions

• mbusrf2_cfg_setup Config Object Initialization function.

void mbusrf2_cfg_setup ( mbusrf2_cfg_t *cfg );

• mbusrf2_init Initialization function.

err_t mbusrf2_init ( mbusrf2_t *ctx, mbusrf2_cfg_t *cfg );

• mbusrf2_set_rst_pin This function is used to set reset pin state.

void mbusrf2_set_rst_pin ( mbusrf2_t *ctx, uint8_t pin_state );

• mbusrf2_send_command This function is used to send a desired command.

err_t mbusrf2_send_command ( mbusrf2_t *ctx, uint8_t cmd, uint8_t *data_in, uint8_t len );

• mbusrf2_send_data This function is used to data in transmitter mode.

err_t mbusrf2_send_data ( mbusrf2_t *ctx, uint8_t *data_in, uint8_t len );

Application Init

Initializes the driver and performs the Click configuration depending on selected DEMO_EXAMPLE macro.

void application_init ( void ) 
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    mbusrf2_cfg_t mbusrf2_cfg;  /**< Click config object. */

    /** 
     * 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.
    mbusrf2_cfg_setup( &mbusrf2_cfg );
    MBUSRF2_MAP_MIKROBUS( mbusrf2_cfg, MIKROBUS_1 );
    if ( UART_ERROR == mbusrf2_init( &mbusrf2, &mbusrf2_cfg ) ) 
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }
    
    mbusrf2_process( );
    mbusrf2_clear_app_buf( );
    Delay_ms ( 500 );
   
    mbusrf2_configure_for_example( );
    
    log_info( &logger, " Application Task " );
}

Application Task

This example contains two examples depending on selected DEMO_EXAMPLE macro: EXAMPLE_TRANSMIT - Device is sending MESSAGE data to be read by receiver. EXAMPLE_RECEIVER - Device is reading transmitted message, and display it on USB UART terminal.

void application_task ( void ) 
{
    mbusrf2_example( );
}

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.
