HI,

I'm currently using the dsPIC33F board with self added codec Si3000, my problem is that i am not able to change the value of TXBUF, even the program execute code such as follow :

TXBUF0 = 0xFFFF;

the value of TXBUF0 remain as 0x0000.

What could be the problem?

THanks in advance
 

Re: Problem with TXBUF0

Whenever you load the value to TXBuffer, it starts transmitting this value to UART.
So you will not be able to see the value of TXBUF.
