Click library

  • Author : Stefan Ilic
  • Date : Oct 2021.
  • Type : SPI type

Software Support

We provide a library for the ccRF3 Click as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.

Package can be downloaded/installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Library Description

This library contains API for ccRF3 Click driver.

Standard 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 );

Example key functions :

  • 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 );

Example Description

This example demonstrates the use of ccRF 3 Click board.

The demo application is composed of two sections :

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
}

The full application code, and ready to use projects can be installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Other Mikroe Libraries used in the example:

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

Additional notes and informations

Depending on the development board you are using, you may need USB UART Click, USB UART 2 Click or RS232 Click to connect to your PC, for development systems with no UART to USB interface available on the board. The terminal available in all MikroElektronika compilers, or any other terminal application of your choice, can be used to read the message.
