Me running code on my machine does not answer any of those questions. Nor do any of your videos. In your video I see a beat of the DDS phase and the TTL pulse. That is not surprising given your experiment. Maybe it is to you but unless you add the required information there is little I can

13:10 <bb-m-labs> build #1544 of artiq is complete: Failure [failed lit_test] Build details are at http://buildbot.m-labs.hk/builders/artiq/builds/1544 blamelist: Robert Jordens <rj@m-labs.hk>

13:28 <sb0> rjo, do the bytes work in the compiler for you? for me it breaks like on the buildbot. it works on whitequark's machine. been trying to track that down...

13:44 <rjo> sb0: haven't tried yet.

14:39 <rjo> sb0: i'll check later. so far at least using a bytes() seems to work just fine.

18:03 <sb0> rjo, why does the servo need a IIR filter?

18:06 <sb0> to reject input noise? even a PI (without D) would be overly sensitive to that?

18:13 <rjo> sb0: have a look at dave's paper.

18:18 <rjo> sb0: the IIR "is" the servo.

19:56 <Ishan_Bansal> sb0: ping

21:00 <Ishan_Bansal> sb0 : could you point out the function of streamer.last in the simlator, I think the problem that I got is my streamer.last is never 1.

22:58 <cr1901_modern> rjo: Could you link dave's paper? I'm curious; did they take an analog control system w/ feedback and convert it to an IIR filter?
