Echo Part II – this one will actually work :D

[ spec ] [ block diagram ] [ github ]

Echo is back! We’re now calling it echo-II, and the goal of this instance is straightforward: make a sound recorder capable of supporting 96 kHz | 32-bit | stereo | PCM recordings over pre-allocated time slots for about 3 weeks, and do all this on a battery (without human intervention).

That’s a mouthful, so the spec is linked at the top. And we all love block diagrams, so here’s one!

That’s for the introduction. Some code coming in on the next one!
