Library Description
Initializes and defines UART bus driver, and defines driver's functions for writing data on the M-BUS terminal.
Key functions:
void mbusmaster_write_byte ( uint8_t input ) - Write one byte dataExamples description
The application is composed of three sections :
void application_task ( )
{
char tmp;
for ( tmp = 0; tmp < 9; tmp++ )
{
mbusmaster_write_byte( demo_message_data[ tmp ] );
}
mikrobus_logWrite( ">> MESSAGE SENT <<", _LOG_LINE );
Delay_ms(2000);
}
Note - M-Bus master communication works at 36v. - This click acts only as 'master', therefore it must be connected to appropriate 'slave'.

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.
