Library Description

The library covers all the necessary functions to control ATA6571 Click board™. Library performs a standard UART interface communication.

Key functions:

• void ata6571_set_operation_mode ( uint8_t op_mode ) - Set device operation mode function.
• void ata6571_write_byte ( uint8_t input ) - Write Single Byte.
• uint8_t ata6571_read_byte( void ) - Read Single Byte.

Examples description

The application is composed of three sections :

• System Initialization - Initializes UART used for communcation and another UART bus used for data logging.
• Application Initialization - Initializes UART driver. In addition to this module is palced inside normal working mode cappable of tranmission and reception of data.
• Application Task - (code snippet) - This is an example which demonstrates the use of ATA6571 Click board™. Tranismiter/Receiver task depend on uncommented code Receiver logging each received byte to the UART for data logging, while transmiter send message each 2 seconds.

void application_task ( )
{
    char tmp;
    uint8_t drdy_flag;

    if ( app_mode == APP_MODE_RECEIVER )
    {
        // RECEIVER - UART polling 

        drdy_flag = ata6571_byte_ready( );

        if ( 1 == drdy_flag )
        {
            tmp = ata6571_read_byte( );
            mikrobus_logWrite( &tmp, _LOG_BYTE );
        }
    }
    else
    {
        // TRANSMITER - TX each 2 sec
      
        for ( tmp = 0; tmp < 9; tmp++ )
        {
            ata6571_write_byte( demo_message_data[ tmp ] );
            Delay_ms( 100 );
        }
        
        mikrobus_logWrite( "   MESSAGE SENT!    ", _LOG_LINE );
        mikrobus_logWrite( "-------------------", _LOG_LINE );
        Delay_ms( 2000 );
    }
}

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.
