STAudioHub time drifts

Question asked by Hami Monsarrat-Chanon on Jun 13, 2017

On the steval-mki138 MEMS microphones dev kit, using the STAudioHub firmware and tools, I am observing a significant time drift between 2 developments kits acquiring the same audio signal at the same time. I am now looking for ways of improving this situation. Is the STAudioHub firmware source code available somewhere? Did anybody try difference hardware or software clock configuration? Any hint would help.
