UART hardware module is available with a number of AVR MCUs. mikroPascal PRO
for AVR UART Library provides comfortable work with the Asynchronous (full
duplex) mode.

You can easily communicate with other devices via RS-232 protocol (for example
with PC, see the figure at the end of the topic – RS-232 HW connection). You need
a AVR MCU with hardware integrated UART, for example ATmega16. Then, simply
use the functions listed below.

- UARTx_Init 
- UARTx_Init_Advanced 
- UARTx_Data_Ready 
- UARTx_Read 
- UARTx_Read_Text 
- UARTx_Write 
- UARTx_Write_Text 

The following routine is for the internal use by compiler only:

- 

UARTx_TX_Idle

Note: AVR MCUs require you to specify the module you want to use. To select the
desired UART, simply change the letter x in the prototype for a number from 1 to 4. 
Number of UART modules per MCU differs from chip to chip. Please, read the
appropriate datasheet before utilizing this library.

Example: 

UART2_Init(); 

initializes UART 2 module.

Note: Some of the AVR MCUs do not support UARTx_Init_Advanced routine.
Please, refer to the appropriate datasheet.
