Library Description
Library provides functions for parsing and communicating with device for communication and controlling pins.
Key functions:
void dotmatrixr_write_ascii ( char *ascii_data ) - Function for showing string to displayvoid dotmatrixr_generic_write ( uint8_t *tx_buf, uint8_t buf_len ) - Function for writing data to devicevoid dotmatrixr_restart ( void ) - Function for restarting deviceExamples description
The application is composed of three sections :
void application_task ( )
{
dotmatrixr_write_ascii( &demo_t1[ 0 ] );
Delay_ms( 1000 );
dotmatrixr_write_ascii( &demo_t2[ 0 ] );
Delay_ms( 1000 );
dotmatrixr_write_ascii( &demo_t3[ 0 ] );
Delay_ms( 1000 );
}

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.
