I have this wired up to a Teensy 4 (3.3v), when powered on the only thing that was coming out of it was low level white noise. The test application is trying to output a sine wave.
So I got the oscilloscope and started probing to check I had it connected properly and the moment I probed WSEL it jumped into life and started working, probing BCLK has the same effect.
When no data is being sent to it probing these pins also removes the low level white noise.
Has anyone got any ideas of what might be going on here?
