Dear Group, I have tried to run the example of DAA operation on C5402 DSK. The board actually goes off-hook, but then the samples from the codec just don't come in. The question is: has anybody encountered such a problem? Could you please give me a clue? I would be grateful for any help. -- Best regards, Michael Kapralov mailto: |

Here is an archive entry with some .asm code for initializing the AD50 on the DSK C5402: http://groups.yahoo.com/group/c54x/message/436 You may not want to do it that way, or you may want to convert to C, but it will explain each bit setting needed, the correct register sequence, and the the timing necessary to get McBSP1 + AD50 moving.

Dear c54x group, I am beginner with DSK TMS320C5402. I try to use McBSP 1 to read and transmit data from and to ADC (TLC320AD50). My question is: Even though i already start receiver and transmitter (set RRST and XRST) i stil can't see the receiver and transmitter started. I check the bits in SPCR11 and SPCR21, the bits already set, but i still can't get the BRINT1 interrupt (in IFR). Am i forgot anything else? Thanks, Herry |
