+### Software Support
+
+We provide a library for the USBUART3 Click on our [LibStock](https://libstock.mikroe.com/projects/view/2422/usb-uart-3-click) 
+page, as well as a demo application (example), developed using MikroElektronika 
+[compilers](http://shop.mikroe.com/compilers). The demo can run on all the main 
+MikroElektronika [development boards](http://shop.mikroe.com/development-boards).
+
+**Library Description**
+
+Initializes and defines UART bus driver, and defines driver's functions for comunication (reading and writing) between USB UART 3 clicks.
+
+Key functions :
+
+- ``` void usbuart3_writeByte(uint8_t input) ``` - Write Single Byte
+- ``` uint8_t usbuart3_readByte() ``` - Read Single Byte
+- ``` uint8_t usbuart3_byteReady() ``` - Check for new byte received
+
+**Examples Description**
+
+The application is composed of three sections :
+
+- System Initialization - Intializes UART module
+- Application Initialization - Driver intialization
+- Application Task - (code snippet) - Checks if new data byte have received in rx buffer (ready for reading),
+  and if ready than reads one byte from rx buffer. In second case aplication task writes
+  message data via UART.
+
+
+```.c
+void applicationTask()
+{
+    char tmp;
+    uint8_t rdyFlag;
+
+// RECEIVER - UART polling 
+
+    rdyFlag = usbuart3_byteReady();
+
+    if (1 == rdyFlag)
+    {
+        tmp = usbuart3_readByte();
+        mikrobus_logWrite( &tmp, _LOG_BYTE );
+    }
+
+// TRANSMITER - TX each 2 sec
+
+ /*   for (tmp = 0; tmp < 9; tmp++)
+    {
+        usbuart3_writeByte( MESSAGE_DATA[tmp] );
+        mikrobus_logWrite( "MESSAGE SENT", _LOG_LINE );
+    }
+    Delay_ms(2000);*/
+
+}
+```
+
+The full application code, and ready to use projects can be found on our 
+[LibStock](https://libstock.mikroe.com/projects/view/2422/usb-uart-3-click) page.

+
+**Additional notes and informations**
+
+Depending on the development board you are using, you may need 
+[USB UART click](http://shop.mikroe.com/usb-uart-click), 
+[USB UART 2 Click](http://shop.mikroe.com/usb-uart-2-click) or 
+[RS232 Click](http://shop.mikroe.com/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](http://shop.mikroe.com/compilers), or any other terminal application 
+of your choice, can be used to read the message.
