USB UART 3 Click

USB UART 3 Click demo application is developed using the NECTO Studio, ensuring compatibility with mikroSDK's open-source libraries and tools. Designed for plug-and-play implementation and testing, the demo is fully compatible with all development, starter, and mikromedia boards featuring a mikroBUS™ socket.

• Date : Apr 2020.
• Type : UART GPS/GNSS type

Software Support

Example Description

This example reads and processes data from USB UART 3 Clicks.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.UsbUart3

Example Key Functions

• usbuart3_cfg_setup Config Object Initialization function.

void usbuart3_cfg_setup ( usbuart3_cfg_t *cfg );

• usbuart3_init Initialization function.

err_t usbuart3_init ( usbuart3_t *ctx, usbuart3_cfg_t *cfg );

• usbuart3_reset Function for reset.

void usbuart3_reset ( usbuart3_t *ctx );

• usbuart3_get_susp Set device mode.

uint8_t usbuart3_get_susp ( usbuart3_t *ctx );

• usbuart3_send_command Function for send command.

void usbuart3_send_command ( usbuart3_t *ctx, char *command );

Application Init

Initializes driver.

void application_init ( void )
{
    log_cfg_t log_cfg;
    usbuart3_cfg_t cfg;

    /** 
     * 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.

    usbuart3_cfg_setup( &cfg );
    USBUART3_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    usbuart3_init( &usbuart3, &cfg );
    
    usbuart3_reset( &usbuart3 );
}

Application Task

Reads the received data.

void application_task ( void )
{
    rsp_size = usbuart3_generic_read( &usbuart3, uart_rx_buffer, PROCESS_RX_BUFFER_SIZE );

    if ( rsp_size > 0 )
    {  
        usbuart3_generic_write( &usbuart3, uart_rx_buffer, rsp_size );
        log_printf( &logger, "%s", uart_rx_buffer );
        memset( uart_rx_buffer, 0, rsp_size );
    }
}

Application Output

This Click board can be interfaced and monitored in two ways:

• Application Output - Use the "Application Output" window in Debug mode for real-time data monitoring. Set it up properly by following this tutorial.
• UART Terminal - Monitor data via the UART Terminal using a USB to UART converter. For detailed instructions, check out this tutorial.

Additional Notes and Information

The complete application code and a ready-to-use project are available through the NECTO Studio Package Manager for direct installation in the NECTO Studio. The application code can also be found on the MIKROE GitHub account.
