Click library

  • Author : MikroE Team
  • Date : maj 2020.
  • Type : SPI type

Software Support

We provide a library for the ccRf2 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 form compilers IDE(recommended way), or downloaded from our LibStock, or found on mikroE github account.

Library Description

This library contains API for ccRf2 Click driver.

Standard key functions :

  • Config Object Initialization function.

    void ccrf2_cfg_setup ( ccrf2_cfg_t *cfg );

  • Initialization function.

    CCRF2_RETVAL ccrf2_init ( ccrf2_t ctx, ccrf2_cfg_t cfg );

  • Click Default Configuration function.

    void ccrf2_default_cfg ( ccrf2_t *ctx );

Example key functions :

  • Function receives RX data from the transmit module of the CC1120 single-chip radio transceiver.

    uint8_t ccrf2_receive_rx_data ( ccrf2_t ctx, uint8_t rx_data );

  • Function sends TX data to the receive module of the CC1120 single-chip radio transceiver.

    void ccrf2_send_tx_data ( ccrf2_t ctx, uint8_t tx_data, uint8_t n_bytes );

  • Function sets RX mode of the CC1120 single-chip radio transceiver on the ccRF 2 Click board.

    void ccrf2_set_rx_mode ( ccrf2_t *ctx );

Examples Description

This example demonstrates the use of ccRF 2 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;
    ccrf2_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.

    ccrf2_cfg_setup( &cfg );
    CCRF2_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    ccrf2_init( &ccrf2, &cfg );
    log_printf( &logger, "----------------------\r\n" );
    log_printf( &logger, " Hardware reset\r\n" );
    ccrf2_hw_reset( &ccrf2 );
    Delay_ms ( 1000 );

    log_printf( &logger, "----------------------\r\n" );
    log_printf( &logger, " Default config\r\n" );
    ccrf2_default_cfg( &ccrf2 );
    Delay_ms ( 1000 );

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

#ifdef DEMO_APP_RECEIVER
    ccrf2_set_rx_mode( &ccrf2 );

    log_printf( &logger, " Receiver mode\r\n" );
#endif
#ifdef DEMO_APP_TRANSMITTER
    ccrf2_set_tx_mode( &ccrf2 );

    log_printf( &logger, " Transmitter mode\r\n" );
#endif

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

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_RECEIVER
    uint8_t num_bytes = ccrf2_receive_rx_data( &ccrf2, &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", ccrf2.packet_counter );
        log_printf( &logger, "\r\n----------------------\r\n" );
    }
#endif
#ifdef DEMO_APP_TRANSMITTER
    ccrf2_send_tx_data( &ccrf2, TEXT_TO_SEND, strlen( TEXT_TO_SEND ) );
    log_printf( &logger, " Sent message: MikroE\r\n" );
    log_printf( &logger, " Packet number: %u\r\n", ccrf2.packet_counter );
    log_printf( &logger, "----------------------\r\n" );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
#endif
}

The full application code, and ready to use projects can be installed directly form compilers IDE(recommneded) or found on LibStock page or mikroE GitHub accaunt.

Other mikroE Libraries used in the example:

  • MikroSDK.Board
  • MikroSDK.Log
  • Click.ccRf2

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.

Button Power Click

0

Button Power Click is a very interesting interactive gadget on a Click board™. It is an integrated capacitive touch sensor display in the form of a button. By utilizing an advanced capacitive touch sensing technology, the CTHS15CIC05ONOFF sensor can successfully replace the traditional mechanical button, allowing very simplified yet reliable user interfaces to be developed. Besides the touch detection, this sensor also features a green power symbol icon with backlight, which makes the Click board™ very useful for building various stylized and visually appealing interfaces.
