Click library

  • Author : Nenad Filipovic
  • Date : Mar 2023.
  • Type : I2C type

Software Support

We provide a library for the USB-C Sink 4 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 USB-C Sink 4 Click driver.

Standard key functions :

  • usbcsink4_cfg_setup Config Object Initialization function.

    void usbcsink4_cfg_setup ( usbcsink4_cfg_t *cfg );
  • usbcsink4_init Initialization function.

    err_t usbcsink4_init ( usbcsink4_t *ctx, usbcsink4_cfg_t *cfg );
  • usbcsink4_default_cfg Click Default Configuration function.

    err_t usbcsink4_default_cfg ( usbcsink4_t *ctx );

Example key functions :

  • usbcsink4_get_type_c_status This function reads the reports of the status of the Type-C port by using the I2C serial interface.

    err_t usbcsink4_get_type_c_status ( usbcsink4_t *ctx, usbcsink4_type_c_status_t *type_c_status );
  • usbcsink4_get_bus_voltage This function reads the live voltage on the VBUS supply for the specified port using the I2C serial interface.

    err_t usbcsink4_get_bus_voltage ( usbcsink4_t *ctx, float *vbus_v );
  • usbcsink4_get_event_status This function reads the reports of the event status to know what has happened on the Type-C/PD port using the I2C serial interface.

    err_t usbcsink4_get_event_status ( usbcsink4_t *ctx, usbcsink4_event_status_t *event_status );

Example Description

This example demonstrates the use of a USB-C Sink 4 Click board by setting DC power requests and control for Type-C connector-equipped devices (TCD).

The demo application is composed of two sections :

Application Init

The initialization of the I2C module and log UART. After driver initialization, the app sets the default configuration.

void application_init ( void ) 
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    usbcsink4_cfg_t usbcsink4_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.
    usbcsink4_cfg_setup( &usbcsink4_cfg );
    USBCSINK4_MAP_MIKROBUS( usbcsink4_cfg, MIKROBUS_1 );
    if ( I2C_MASTER_ERROR == usbcsink4_init( &usbcsink4, &usbcsink4_cfg ) ) 
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }

    if ( USBCSINK4_ERROR == usbcsink4_default_cfg ( &usbcsink4 ) )
    {
        log_error( &logger, " Default configuration." );
        for ( ; ; );
    }

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

Application Task

The demo app displays the reports of the Type-C port, active legacy charging mode status, and live voltage measurements on the VBUS supply for the specified port.

void application_task ( void ) 
{
    usbcsink4_display_type_c_status( );
    Delay_ms ( 100 );

    usbcsink4_display_chrg_mode( );
    Delay_ms ( 100 );

    usbcsink4_display_bus_voltage( );
    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.USBCSink4

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.
