Click library

  • Author : Stefan Filipovic
  • Date : Feb 2021.
  • Type : I2C type

Software Support

We provide a library for the SolidSwitch 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 SolidSwitch Click driver.

Standard key functions :

  • solidswitch_cfg_setup Config Object Initialization function.

    void solidswitch_cfg_setup ( solidswitch_cfg_t *cfg );
  • solidswitch_init Initialization function.

    err_t solidswitch_init ( solidswitch_t *ctx, solidswitch_cfg_t *cfg );
  • solidswitch_default_cfg Click Default Configuration function.

    err_t solidswitch_default_cfg ( solidswitch_t *ctx );

Example key functions :

  • solidswitch_write_single SolidSwitch I2C writing logic state function.

    err_t solidswitch_write_single ( solidswitch_t *ctx, uint8_t logic_state );
  • solidswitch_read_single SolidSwitch I2C reading logic state function.

    err_t solidswitch_read_single ( solidswitch_t *ctx, uint8_t *logic_state );
  • solidswitch_reset SolidSwitch reset function.

    void solidswitch_reset ( solidswitch_t *ctx );

Example Description

This example demonstrates the use of SolidSwitch Click board.

The demo application is composed of two sections :

Application Init

Initializes the driver and logger and enables the Click board.


void application_init ( void )
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    solidswitch_cfg_t solidswitch_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.

    solidswitch_cfg_setup( &solidswitch_cfg );
    SOLIDSWITCH_MAP_MIKROBUS( solidswitch_cfg, MIKROBUS_1 );
    err_t init_flag = solidswitch_init( &solidswitch, &solidswitch_cfg );
    if ( init_flag == I2C_MASTER_ERROR ) 
    {
        log_error( &logger, " Application Init Error. " );
        log_info( &logger, " Please, run program again... " );

        for ( ; ; );
    }

    solidswitch_default_cfg ( &solidswitch );
    log_info( &logger, " Application Task " );
}

Application Task

Enables different outputs every 3 seconds and displays all enabled outputs on USB UART.


void application_task ( void )
{
    solidswitch_write_single ( &solidswitch, SOLIDSWITCH_ENABLE_OUT0 | SOLIDSWITCH_ENABLE_OUT1 );
    solidswitch_display_enabled_channels( );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    solidswitch_write_single ( &solidswitch, SOLIDSWITCH_ENABLE_OUT6 | SOLIDSWITCH_ENABLE_OUT7 );
    solidswitch_display_enabled_channels( );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    solidswitch_write_single ( &solidswitch, SOLIDSWITCH_ENABLE_ALL_OUTPUTS );
    solidswitch_display_enabled_channels( );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    solidswitch_write_single ( &solidswitch, SOLIDSWITCH_DISABLE_ALL_OUTPUTS );
    solidswitch_display_enabled_channels( );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
}

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.SolidSwitch

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.
