ccRF 3 Click

ccRF 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.

Example Description

This example demonstrates the use of ccRF 3 Click board.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.ccRF3

Example Key Functions

• ccrf3_cfg_setup Config Object Initialization function.

void ccrf3_cfg_setup ( ccrf3_cfg_t *cfg );

• ccrf3_init Initialization function.

err_t ccrf3_init ( ccrf3_t *ctx, ccrf3_cfg_t *cfg );

• ccrf3_default_cfg Click Default Configuration function.

err_t ccrf3_default_cfg ( ccrf3_t *ctx );

• ccrf3_cmd_strobe Set command strobe function.

uint8_t ccrf3_cmd_strobe ( ccrf3_t *ctx, uint8_t cmd )

• ccrf3_send_tx_data Send TX data function.

void ccrf3_send_tx_data ( ccrf3_t *ctx, uint8_t *tx_data, uint8_t n_bytes );

• ccrf3_receive_rx_data Receive RX data function.

uint8_t ccrf3_receive_rx_data ( ccrf3_t *ctx, uint8_t *rx_data );

Application Init

Initializes the driver, performs the default configuration and enables the selected mode.

void application_init ( void )
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    ccrf3_cfg_t ccrf3_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_printf( &logger, " Application Init \r\n" );

    // Click initialization.
    ccrf3_cfg_setup( &ccrf3_cfg );
    CCRF3_MAP_MIKROBUS( ccrf3_cfg, MIKROBUS_1 );
    if ( SPI_MASTER_ERROR == ccrf3_init( &ccrf3, &ccrf3_cfg ) )
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }
    
    log_printf( &logger, "----------------------\r\n" );
    log_printf( &logger, " Hardware reset\r\n" );
    ccrf3_hw_reset( &ccrf3 );
    Delay_ms ( 1000 );
    
    if ( CCRF3_ERROR == ccrf3_default_cfg ( &ccrf3 ) )
    {
        log_error( &logger, " Default configuration." );
        for ( ; ; );
    }
    
    log_printf( &logger, "----------------------\r\n" );
#ifdef DEMO_APP_TRANSMITTER
    ccrf3_set_tx_mode( &ccrf3 );
    
    log_printf( &logger, " Transmitter mode\r\n" );
#else
    ccrf3_set_rx_mode( &ccrf3 );
    
    log_printf( &logger, " Receiver mode\r\n" );
#endif

    log_printf( &logger, "----------------------\r\n" );
    Delay_ms ( 100 );
    
    log_printf( &logger, " Application Task \r\n" );
    log_printf( &logger, "----------------------\r\n" );
}

Application Task

Depending on the selected mode, it reads the received data or sends the desired message every 2 seconds. All data is being logged on the USB UART where you can track their changes.

void application_task ( void )
{
#ifdef DEMO_APP_TRANSMITTER
    ccrf3_send_tx_data( &ccrf3, TEXT_TO_SEND, strlen( TEXT_TO_SEND ) );
    log_printf( &logger, " Sent message: MikroE\r\n" );
    log_printf( &logger, " Packet number: %u\r\n", ccrf3.packet_counter );
    log_printf( &logger, "----------------------\r\n" );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
#else
    uint8_t num_bytes = ccrf3_receive_rx_data( &ccrf3, &rx_buffer[ 0 ] );
    if ( num_bytes )
    {
        log_printf( &logger, " Received message: " );
        for ( uint8_t cnt = 3; cnt < rx_buffer[ 0 ]; cnt++ )
        {
            log_printf( &logger, "%c", rx_buffer[ cnt ] );
        }
        log_printf( &logger, " Packet number: %u", ccrf3.packet_counter );
        log_printf( &logger, "\r\n----------------------\r\n" );
    }
#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.
