EnOcean 2 Click

Click library

  • Author : MikroE Team
  • Date : jul 2020.
  • Type : UART GSM/IOT type

Software Support

We provide a library for the EnOcean2 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 EnOcean2 Click driver.

Standard key functions :

  • Config Object Initialization function.

    void enocean2_cfg_setup ( enocean2_cfg_t *cfg );

  • Initialization function.

    ENOCEAN2_RETVAL enocean2_init ( enocean2_t ctx, enocean2_cfg_t cfg );

Example key functions :

  • EnOcean Serial Protocol ( ESP3 ) module initialization.

    void enocean2_init_rx_buff ( enocean2_t ctx, enocean2_ring_buffer_t rb, enocean2_rx_data_t *rx_str );

  • The function push recieved character to ring buffer.

    uint8_t enocean2_rx ( enocean2_ring_buffer_t *rb, uint8_t rx_data );

  • Implements state machine for recieving packets. It should be called in loop.

    uint8_t enocean2_packet_recieve ( enocean2_t ctx, enocean2_ring_buffer_t rb );

Examples Description

This example reads and processes data from EnOcean 2 clicks.

The demo application is composed of two sections :

Application Init

Initializes driver init and initializes chip and sets callback handler.


void application_init ( void )
{
    log_cfg_t log_cfg;
    enocean2_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.

    enocean2_cfg_setup( &cfg );
    ENOCEAN2_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    enocean2_init( &enocean2, &cfg );

    enocean2_rx_data.rx_buffer   = &rx_buffer[ 0 ];
    enocean2_rx_data.rx_size     = ENOCEAN2_RX_BUFFER_SIZE;
    enocean2_rx_data.data_buffer = &data_buffer[ 0 ];
    enocean2_rx_data.data_size   = ENOCEAN2_RX_BUFFER_SIZE;

    enocean2_init_rx_buff( &enocean2, &enocean2_rb, &enocean2_rx_data );
    enocean2_set_callback_handler( &enocean2, callback_handler );
}

Application Task

It checks if a switch is pressed, and logs an appropriate message to the uart terminal.


void application_task ( void )
{
    enocean2_process( );
}  

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.EnOcean2

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.
