Library Description

The library contains basic functions for working with ThingMagic clicks. The user has the ability to read tags and rssi values.

Key functions:

• int8_t thingmagic_get_tag_rssi ( void ) - Get Tag RSSI value
• void thingmagic_tag_parser ( thingmagic_data_t *data_obj ) - Gets Tag value after parsing
• void thingmagic_process ( uint8_t rsp_data ) - General collecting response function

Examples description

The application is composed of three sections :

• System Initialization - Initialize UART module and all necessary GPIO pins
• Application Initialization - Initialize driver init and starts default configuration module
• Application Task - Reads TAG information and RSSI value of the TAG

void application_task ( )
{
    if ( thingmagic_get_data_status( ) == 1 )
    {
        thingmagic_tag_parser( &tag );

        mikrobus_logWrite( ">> TAG INFO: ", _LOG_TEXT );
        for( cnt = 0; cnt < 12; cnt++ )
        {
            ByteToHex( tag.tag_buf[ cnt ], demo_text );
            mikrobus_logWrite( " 0x", _LOG_TEXT );
            mikrobus_logWrite( demo_text, _LOG_TEXT );
        }
        mikrobus_logWrite( " ", _LOG_LINE );
        mikrobus_logWrite( ">> TAG RSSI: ", _LOG_TEXT );
        IntToStr( tag.tag_rssi, demo_text );
        mikrobus_logWrite( demo_text, _LOG_LINE );
        
        thingmagic_reset_data( );
    }
}

• 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.
