Click library

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

Software Support

We provide a library for the Calypso 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 Calypso Click driver.

Standard 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 );

Example key functions :

  • 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 );

Example Description

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

The demo application is composed of two sections :

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( );
}

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.Calypso

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. UART terminal is available in all MikroElektronika compilers.

Expand 12 Click

0

Expand 12 Click is a compact add-on board that contains a multi-port I/O expander. This board features the MAX7300, a general-purpose I/O expander providing remote I/O expansion for most MCU’s families from Maxim Integrated, now part of Analog Devices. The MAX7300 comes in a 28-port configuration and allows easy addition of I/O through a standard I2C serial interface. Each port is user-configurable to either a logic input or logic output, capable of sinking 10mA and sourcing 4.5mA.
