Who working with RAC mode in the AD7682/AD7689?
My problem is , that the ADC doesn't want to response right. I made all that are wrote in instuction, but
this method of data transfer (RAC) no correctly. May be there are so little information....I don't know..
I writing the CFG configuration such as 0x39FF after power up.
Farther, I must to hold DIN line in low, that it cans only by sending 0x0000 in CFG without the register overwriting.
As response, ADC must to give me right digital values of signal. Temperature detector was disabled if CFG=0x38FF, but I
receving this value all the time !!!!!!
Settings: WITHOUT A BUSY INDICATOR
SINGLE ENDED CHANNEL FROM IN0 T0 IN3
I think that ADC doesn't understand my CFG configuration. Why?
What is problem ?
