FT Click

FT 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.

• Type : UART type

Software Support

Example Description

This example demonstrates the use of an FT Click board by showing the communication between the two Click boards.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.Ft

Example Key Functions

• ft_cfg_setup Config Object Initialization function.

void ft_cfg_setup ( ft_cfg_t *cfg ); 

• ft_init Initialization function.

err_t ft_init ( ft_t *ctx, ft_cfg_t *cfg );

• ft_get_data_status Use this function to get current status of data

uint8_t ft_get_data_status ( ft_t *ctx );

• ft_get_data Use this function to read received data

uint16_t ft_get_data ( ft_t *ctx, uint8_t *data_buf );

• ft_send_package Use this function to send data to other module

void ft_send_package ( ft_t *ctx, uint8_t *data_buf, uint16_t len, uint8_t queue );

Application Init

Initalizes device and makes an initial log.

void application_init ( void )
{
    log_cfg_t log_cfg;
    ft_cfg_t ft_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.
    ft_cfg_setup( &ft_cfg );
    FT_MAP_MIKROBUS( ft_cfg, MIKROBUS_1 );
    if ( UART_ERROR == ft_init( &ft, &ft_cfg ) ) 
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }

#ifdef DEMO_APP_TRANSMITTER
    log_printf( &logger, " Application Mode: Transmitter\r\n" );
#else
    log_printf( &logger, " Application Mode: Receiver\r\n" );
#endif
    log_info( &logger, " Application Task " );
}

Application Task

Depending on the selected application mode, it reads all the received data or sends the desired text message once per second.

void application_task ( void )
{
#ifdef DEMO_APP_TRANSMITTER
    ft_send_package( &ft, DEMO_TEXT_MESSAGE, strlen( DEMO_TEXT_MESSAGE ), 1 );
    log_printf( &logger, " Sent data: %s", ( char * ) DEMO_TEXT_MESSAGE );
    Delay_ms ( 1000 );
#else
    uint8_t rsp_data_buf[ FT_MAX_DATA_BUFFER ] = { 0 };
    uint8_t rx_byte = 0;
    if ( 1 == ft_generic_read( &ft, &rx_byte, 1 ) )
    {
        ft_isr_parser( &ft, rx_byte ); 
        if ( FT_NEW_DATA_AVAILABLE == ft_get_data_status( &ft ) )
        {
            if ( ft_get_data( &ft, rsp_data_buf ) )
            {
                log_printf( &logger, " Received data: %s", rsp_data_buf );
            }
        }
    }
#endif
}

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.
