Hello all,

I am currently working on the UART( RS232) of the ADSP21161N in order
to   communicate with the pc via the serial port.
I have already done an interface with a max232. I found an application
note (EE191) in which they give the software to use but I don't know
how  use and call all these functions in the main C program

these functions are :
1. Setup_UART( float DSP_Frequency, float BAUD )
2. char UartRx();
3. UartTx_Word( char word )
4. UartTx_Buffer( char * buf, int size )
5. UartTx_Service( void )

 Please can somebody explain me how use the function 2,3,4 and 5 ?

Thanks
