Library Description
The library covers all the necessary functions to control CXPI click board. Library performs a standard UART communication.
Key functions:
void cxpi_write_byte ( uint8_t input )
- Write Single Byte.uint8_t cxpi_read_byte ( void )
- Read Single Byte.uint8_t cxpi_byte_ready ( void )
- Check for new byte received.Examples description
The application is composed of three sections :
void application_task ( )
{
if ( app_mode == APP_MODE_TRANSMITER )
{
mikrobus_logWrite( "----------------------", _LOG_LINE );
mikrobus_logWrite( "", _LOG_LINE );
cxpi_write_data( &demo_message_data[ 0 ], 9 );
mikrobus_logWrite( " TX Data: ", _LOG_TEXT );
mikrobus_logWrite( demo_message_data, _LOG_LINE );
Delay_ms( 5000 );
}
}

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.
