Re: AD7685 SPI problem

$

I having problem to read from a single AD7685 ADC's using an MSP430F149 microcontroller. The problem is, following setting the CNV pin high and wait plenty (50us) for letting the conversion to be completed I read two bytes from the ADC's, but it seems what I am doing is incorrect as the values of the 2 bytes are always 0x00.

 

I used GPIO to analog SPI.Choosing CS mode 3_wire, no busy indicator.

 

 

Would anyone help me with a sample code ideally Msp430, but any hint would be nice that could help me understand better how to read from the ADC please?
