Click library

  • Author : Stefan Ilic
  • Date : Jun 2021.
  • Type : UART type

Software Support

We provide a library for the USBUART4 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 USBUART4 Click driver.

Standard key functions :

  • usbuart4_cfg_setup Config Object Initialization function.

    void usbuart4_cfg_setup ( usbuart4_cfg_t *cfg );
  • usbuart4_init Initialization function.

    err_t usbuart4_init ( usbuart4_t *ctx, usbuart4_cfg_t *cfg );

Example key functions :

  • usbuart4_pwr_ctrl This function sets the Click turns Click on.

    void usbuart4_pwr_ctrl ( usbuart4_t *ctx, uint8_t state );
  • usbuart4_set_cts This function sets CTS pin.

    void usbuart4_set_cts ( usbuart4_t *ctx, uint8_t state );
  • usbuart4_send_command This function is used for sending commands.

    void usbuart4_send_command ( usbuart4_t *ctx, char *command );

Example Description

This example reads and processes data from USB UART 4 clicks.

The demo application is composed of two sections :

Application Init

Initializes driver and power module.


void application_init ( void ) {
    log_cfg_t log_cfg;  /**< Logger config object. */
    usbuart4_cfg_t usbuart4_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 " );
    Delay_ms ( 100 );

    // Click initialization.

    usbuart4_cfg_setup( &usbuart4_cfg );
    USBUART4_MAP_MIKROBUS( usbuart4_cfg, MIKROBUS_1 );

    err_t init_flag  = usbuart4_init( &usbuart4, &usbuart4_cfg );
    if ( UART_ERROR == init_flag ) {
        log_error( &logger, " Application Init Error. " );
        log_info( &logger, " Please, run program again... " );

        for ( ; ; );
    }

    app_buf_len = 0;

    usbuart4_pwr_ctrl( &usbuart4, USBUART4_POWER_ON );
    usbuart4_set_cts( &usbuart4, USBUART4_CTS_NO_ACTIVE );
    usbuart4_set_mode( &usbuart4, USBUART4_MODE_NORMAL );

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

Application Task

Reads data and echos it back to device and logs it to board.


void application_task ( void ) {
    app_buf_len = usbuart4_generic_read( &usbuart4, app_buf, PROCESS_BUFFER_SIZE );

    if ( app_buf_len > 0 ) {
        log_printf( &logger, "%s", app_buf );
        memset( app_buf, 0, PROCESS_BUFFER_SIZE );
    }
}

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.USBUART4

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.
