I like the use of the ADC, How does it perform? Is it worth exploring more?

I have my first bare metal example running !

It's not yet one that I compiled myself. That's the next step.

How do you actually control the ADC, it isn't actually a file so there must be some kind of driver thing somewhere which is setting sample rates and doing buffering etc (I hope) .

I've now ported my light organ design from Arduino to SAMA5D4 (including the fft library)

Good reuse and demonstration.

It is always good to get back to basics when evaluating new boards.

... and with this post I'm claiming dibs on being the first among all roadtest and designchallenge contenders who cross-compiled and ran a c program that accesses I/O on this very board [View:/resized-image/__size/16x16/__key/commentfiles/f7d226abd59f475c9d224a79e3f0ec07-da26c4d2-dc89-4cde-ae71-697f3910624a/contentimage_5F00_1.png:16:16].

If we find prior art here on element14, I'll remove the trophy from my bookshelves.
