Calypso Click

Calypso 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.

Click Library

• Author : Stefan Ilic
• Date : Mar 2024.
• Type : UART type

Software Support

Example Description

This example demonstrates the use of Calypso Click board by processing the incoming data and displaying them on the USB UART.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.Calypso

Example Key Functions

• calypso_cfg_setup Config Object Initialization function.

void calypso_cfg_setup ( calypso_cfg_t *cfg );

• calypso_init Initialization function.

err_t calypso_init ( calypso_t *ctx, calypso_cfg_t *cfg );

• calypso_default_cfg Click Default Configuration function.

err_t calypso_default_cfg ( calypso_t *ctx );

• calypso_set_app_mode This function is used to set selected APP mode of Calypso Click board.

err_t calypso_set_app_mode ( calypso_t *ctx, uint8_t mode_sel );

• calypso_hw_reset This function is used to perform HW reset.

void calypso_hw_reset ( calypso_t *ctx );

• calypso_send_cmd This function is used to send a desired command.

void calypso_send_cmd ( calypso_t *ctx, uint8_t *at_cmd_buf );

Application Init

Initializes the driver and places AT command mode, tests the communication, and after that restarts the device, and performs example configuration.

void application_init ( void ) 
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    calypso_cfg_t calypso_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_info( &logger, " Application Init " );

    // Click initialization.
    calypso_cfg_setup( &calypso_cfg );
    CALYPSO_MAP_MIKROBUS( calypso_cfg, MIKROBUS_1 );
    if ( UART_ERROR == calypso_init( &calypso, &calypso_cfg ) ) 
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }
    
    if ( CALYPSO_ERROR == calypso_default_cfg ( &calypso ) )
    {
        log_error( &logger, " Default configuration." );
        for ( ; ; );
    }

    calypso_configure_for_example( );
    
    log_info( &logger, " Application Task " );
}

Application Task

It creates a connection to the TCP-UDP echo server, sends a message to it reads it back, displaces it on the UART terminal, and then closes the connection.

void application_task ( void ) 
{
    calypso_example( );
}

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.
