Library Description

The library contains functions to provide communication between 2 or more click boards.

Key functions:

• void ft_send_package( uint8_t *data_buf, uint16_t len, uint8_t queue ) - Sends full package to other module
• void ft_process ( uint8_t rsp_data ) - Collecting and preserving data received via uart interrupt routine
• uint16_t ft_get_data ( uint8_t *data_buf ) - Gets new received data

Examples description

The application is composed of three sections :

• System Initialization - Initialize UART module and sets aplication mode (RX or TX)
• Application Initialization - Initialize driver init
• Application Task - RX mode : Reads and logs new receive data. TX mode : sends (MikroE) data every 1 seconds.

void application_task ( )
{
    if ( app_mode == APP_MODE_RX )
    {
        if ( ft_get_data_status( ) == FT_NEW_DATA_AVAILABLE )
        {
            rsp_data_num = ft_get_data( &rsp_data_buf[ 0 ] );
            if( rsp_data_num != 0 )
            {
                mikrobus_logWrite( "---------------------------", _LOG_LINE );
                mikrobus_logWrite( "--> READ: ", _LOG_TEXT );
                mikrobus_logWrite( rsp_data_buf, _LOG_LINE );
                mikrobus_logWrite( "---------------------------", _LOG_LINE );
            }
        }
    }
    else
    {
        mikrobus_logWrite( "--------------------------", _LOG_LINE );
        mikrobus_logWrite( "-->  SEND MIKROE DATA  <--", _LOG_LINE );
        mikrobus_logWrite( "--------------------------", _LOG_LINE );
        ft_send_package( &MIKROE_DATA_BUF[ 0 ], MIKROE_DATA_BUF_LEN, MIKROE_DATA_QUEUE );
        Delay_ms( 1000 );
    }
}

Note - Before the start program check uart interrupt routine in the Click_FT_other peripherals file.

• UART Library
• Conversions library

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. The terminal available in all MikroElektronika compilers, or any other terminal application of your choice, can be used to read the message.
