I am trying to program the AD9910 to exploit each functionality.
I have a question regarding Profile pins control. Can I modify the contents of a profile when an onther profile is running? I am pretty sure that I can do it. But there are any "unsaid" restriction in doing it?
When I switch the profile, often the DDS does not change and more often the DDS1 seems to stop working completely.
I am pretty sure that I am sending correctly the word required so I am doubtful about the way ("timing") I update the profile pins.
To change the profile I am using a shiftregister 3 bits without latch and I am writing slowly, so the DDS can detect each single profile pins change before to reach the required profile, but sometime got crisis
Doea anybody have some suggestions?
