Hello  all,

I have to make one application which uses two UARTS so i added uart_lite given in IP catalog and then make the TX and RX of the IP external. I have made max3232 circuit which works at 3.3 volts and i am connecting the TX and RX with max3232 11th and 12th pin which is TX and RX. I wrote the C code in which i am constantly sending "a" but am recieving some junk data on the terminal. I did check if the baud rate kept was diff but it was the same i reduced the baud rate than also the same thing...

Am i going wrong somewhere.???

Any help would be appreciated ..

I got the output  correct now......

But i had to keep the baud rate at the pc end lower than the baud rate at the FPGA side....this thing i did not understand....

Perhaps the clock to the UART in the FPGA is less than it is expecting.

May be yes..but i did try it again and this time the baud rate kept was same and it worked properly so may be i might have mistaken the first time....
