Nano LR Click

Nano LR 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.

Software Support

Example Description

This example reads and processes data from Nano LR Clicks.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.NanoLR

Example Key Functions

• nanolr_cfg_setup Config Object Initialization function.

void nanolr_cfg_setup ( nanolr_cfg_t *cfg );

• nanolr_init Initialization function.

err_t nanolr_init ( nanolr_t *ctx, nanolr_cfg_t *cfg );

• nanolr_default_cfg Click Default Configuration function.

void nanolr_default_cfg ( nanolr_t *ctx );

• nanolr_send_data This function sends data command depends on the chosen network protocol.

void nanolr_send_data ( nanolr_t *ctx, uint8_t *tx_data, uint8_t length );

• nanolr_uart_isr This function reads response bytes from the device and sets flag after each received byte.

void nanolr_uart_isr ( nanolr_t *ctx );

• nanolr_rsp_rdy This function checks if the response is ready.

uint8_t nanolr_rsp_rdy ( nanolr_t *ctx );

Application Init

Initializes the driver, and performs the Click default configuration.

void application_init ( void )
{
    log_cfg_t log_cfg;
    nanolr_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.

    nanolr_cfg_setup( &cfg );
    NANOLR_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    nanolr_init( &nanolr, &cfg );

    nanolr_default_cfg( &nanolr );

    log_printf( &logger,  "----  Nano LR Click ----\r\n" );

#ifdef DEMO_APP_RECEIVER
    log_printf( &logger,  "---- RECEIVER MODE ----\r\n" );
#endif
    
#ifdef DEMO_APP_TRANSMITTER
    log_printf( &logger,  "---- TRANSMITER MODE ----\r\n" );
#endif 
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
}

Application Task

Depending on the selected mode, it reads all the received data or sends a desired message every 2 seconds. All data is being displayed on the USB UART.

void application_task ( void )
{    
#ifdef DEMO_APP_RECEIVER
    nanolr_process( );
#endif

#ifdef DEMO_APP_TRANSMITTER
    nanolr_send_data( &nanolr, TEXT_TO_SEND, strlen( TEXT_TO_SEND ) );
    log_printf( &logger, "The message \"%s\" has been sent!\r\n", ( uint8_t * ) TEXT_TO_SEND );
    log_printf( &logger, "------------------------------------------------------------\r\n" );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
#endif
}

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.
