Click library

  • Author : Stefan Ilic
  • Date : Aug 2021.
  • Type : I2C type

Software Support

We provide a library for the USBCSource 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 USBCSource Click driver.

Standard key functions :

  • usbcsource_cfg_setup Config Object Initialization function.

    void usbcsource_cfg_setup ( usbcsource_cfg_t *cfg );
  • usbcsource_init Initialization function.

    err_t usbcsource_init ( usbcsource_t *ctx, usbcsource_cfg_t *cfg );

Example key functions :

  • usbcsource_hw_reset HW reset function.

    void usbcsource_hw_reset ( usbcsource_t *ctx );
  • usbcsource_get_alert_status Get alert status function.

    void usbcsource_get_alert_status ( usbcsource_t *ctx, alert_status_t *alert_status_data );
  • usbcsource_set_pdo_config Set PDO configuration function.

    uint8_t usbcsource_set_pdo_config ( usbcsource_t *ctx, pdo_config_t pdo_cfg_data );

Example Description

This is an example that demonstrates the use of the USB-C Source Click board.

The demo application is composed of two sections :

Application Init

Initialization driver enables - I2C, set hardware reset and default configuration and display configuration of the five PDOs, also write log.


void application_init ( void ) {
    log_cfg_t log_cfg;  /**< Logger config object. */
    usbcsource_cfg_t usbcsource_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.
    usbcsource_cfg_setup( &usbcsource_cfg );
    USBCSOURCE_MAP_MIKROBUS( usbcsource_cfg, MIKROBUS_1 );
    err_t init_flag = usbcsource_init( &usbcsource, &usbcsource_cfg );
    if ( I2C_MASTER_ERROR == init_flag ) {
        log_error( &logger, " Application Init Error. " );
        log_info( &logger, " Please, run program again... " );

        for ( ; ; );
    }

    usbcsource_default_config( &usbcsource );
    Delay_ms ( 500 );

    log_printf( &logger, " PDO 1 - Voltage = %.2f V \r\n", pdo_data.vtg_data );
    log_printf( &logger, " PDO 1 - Current = %.2f A \r\n", pdo_data.curr_data );
    log_printf( &logger, "- - - - - - - - - - - - - -\r\n" );

    usbcsource_get_pdo_config( &usbcsource, USBCSOURCE_SEL_PDO2, &pdo_data );

    log_printf( &logger, " PDO 3 - Voltage = %.2f V \r\n", pdo_data.vtg_data );
    log_printf( &logger, " PDO 3 - Current = %.2f A \r\n", pdo_data.curr_data );
    log_printf( &logger, "- - - - - - - - - - - - - -\r\n" );

    usbcsource_get_pdo_config( &usbcsource, USBCSOURCE_SEL_PDO4, &pdo_data );
    log_printf( &logger, " PDO 4 - Voltage = %.2f V \r\n", pdo_data.vtg_data );

    log_printf( &logger, "- - - - - - - - - - - - - -\r\n" );

    usbcsource_get_pdo_config( &usbcsource, USBCSOURCE_SEL_PDO5, &pdo_data );
    log_printf( &logger, " PDO 5 - Voltage = %.2f V \r\n", pdo_data.vtg_data );

    log_printf( &logger, "- - - - - - - - - - - - - -\r\n" );

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

Application Task

In this example, we show port status, monitoring, and connections. All data logs write on USB uart changes every 5 sec.


void application_task ( void ) {
    usbcsource_get_port_status( &usbcsource, &port_status );
    display_port_status( );
    Delay_ms ( 100 );
    log_printf( &logger, "- - - - - - - - - - - - - - " );
    log_printf( &logger, "- - - - - - - - - - - - - -\r\n" );

    usbcsource_get_monitoring_status( &usbcsource, &monitor_status );
    display_monitoring_status( );
    Delay_ms ( 100 );
    log_printf( &logger, "- - - - - - - - - - - - - - " );
    log_printf( &logger, "- - - - - - - - - - - - - -\r\n" );

    usbcsource_get_connection_status( &usbcsource, &conn_status );
    display_connection_status( );
    Delay_ms ( 100 );
    log_printf( &logger, "- - - - - - - - - - - - - - " );
    log_printf( &logger, "- - - - - - - - - - - - - -\r\n" );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    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.USBCSource

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.
