Hi

Any of you provide the library file for mcp4728.

Don't need to, if you have the CCS compiler you already have it in the examples directory.
As was said earlier, look at the examples already provided.
Also, search this forum for sisr.c to find usag ...

You must first understand that an interrupt means only ONE character is
available and you should getc() only ONE character then get out of the
ISR ASAP similar to this:

#INT_RDA
void serial_rec ...

You need to use buffers. Have a look at the CCS example ex_sisr.c. See how they do it,try with one UART, then copy it for the 2nd UART. It does work for 2 UARTs both running at 115k200.
