I tried to to test the SPI communication (clock 4MHz) between an ATmega8 and an AD7176. Therefor I send to the AD 0x47 to read the ID register. With an logic analyzer I see that the AD do not respond to my command
I look the MISO signal with the Oscilloscope and it seem that the signal is not stable!
I don't know what to do to establish the communication, or is my AD the problem?
I really need your help!
Thanks a lot
