[SOLVED] PIC24FV UART Configuration issue

[vijitron]

Hi
I am facing issues in UART communication, PIC24FV32KA302 .

i configured the UART for 9600 baud rate, but unfortunately i am receiving junk values in the terminal.
I suspected the OSC configuration, but i don't really know weather i did configured right way for 8Mhz.
below is what i did,

Please let me know how to correct this problem.

#define FOSC 80000000L

I guess, you are the first one who received a PIC 24 with 80 MHz internal oscillator!

Omg:-o, its my mistake. Thank you for noting that. Now its working.
When using printf , some characters missing at terminal.
So i wrote my own Putstr function verifying the while(! TRMT)

Now its working fine.

Thanks again
