Hi all,
I have trouble with the DAC8760 in the daisy chain using. I use four DAC8760 chips and connect them in daisy chain as the datasheet shows.I use the TM4C1294NCPDT as the host processor. I can send command and control the daisy chain through SPI interface.The chips can communicate each other with tthe shifte register inside themselve.However, somtimes the forth chip can not send the SDO signals to the host processor.More strangely , when I do a POR to the board ,the second to forth chip can not send SPI signals anymore though the fiirst chip can receive the SDI from the host processor. Could kindly remind me some conditions and configurations for the use of daisy chain with DAC8760?
