Newbie Doubt on TMS320F2812's McBSP - arm_techie arm_user - Sep 13 8:10:41 2007



Hi,
    I am using TI's TMS320F2812 DSP controller.
When I tried McBSP in Digital Loopback mode without compression, it is
working fine.
But the problem arises when I am trying to compand the data. For that I am
doing the following settings.

***********************************************************************************************
************************************
SPCR1 = 0x8000          //digital loopback mode enabled

RWDLEN2=000b          //corresponding to Wordlength of bits
RWDLEN1=000b          //corresponding to Wordlength of bits
XWDLEN2=000b          //corresponding to Wordlength of bits
XWDLEN1=000b          //corresponding to Wordlength of bits

XCOMPAND=10b          //Selects the u-Law companding at Transmitting side
RCOMPAND=10b          //Selects the u-Law companding at Receiving side
***********************************************************************************************
************************************

I am not able to get the data that I am transmitting. Is there anything else
that I am missing out somewhere?
