I was waiting for your proto

nothing, only wanted to know if the I2S was as great as it seems (with sound save)

I could not get him to decode I2S as a sound. Only as data.

It's quiet down here. Too quiet.

This is normal practice. This table can be used by downloadable software. And these vectors will always be true, even if the system software is updated.

Exactly.

so bad the 16channels costs 3x the 8channels version It is because 8x is only simple Cypress controller and it support only 24MS/s. 16x contain FPGA and can up to 100MS/s with 1 channel. So it is still cheaper than other LAs. I bought for $37 (more than year ago) . The cheapest LA in 16ch streaming...

Agree with Chilly Willy.

What do you want to get?

SCOR tells the host a new frame began and that the following frame will be the the first bit of P-W Yes. That is exactly what I trying to say, but from the viewpoint of probable realization in the hardware. In those days no one was to want to complicate any of IC part, because of many reasons, some...

To be honest, i know the answer was on this picture...but I was unable to read it correctly :( but still, if it read 2 frames (to get S0 & S1), it should mean SCOR should be set for 2 frames no ? I understand you. But the only way to find sync is get to subcode bytes with some unique states. So to ...

which prove MCD is 1x CD drive

and you do understand why I wanted to check fi SCOR was in sync with IRQ which 1/75sec too

Yes, but nIRQ is not 1/75. It is most like 1/150.

THANKS !!! awesome !!! You're welcome. so, for me, the only question still here (for now) is why SCOR is only 1 frame and not 2 like it should be : A sector is 98 frames, with 2 frames for S0/S1 synchronisation word and 96 frames for subcode = 96bit for P, 96bit for Q,...... so where is the second ...

Like I said, I'd like to confirm if there is any link between comm, sub and data....or they're totally independant so could you measure IRQ / WFCK / LRCK on the same timing ? Here we come.

OK. I think we can do first approach to make FLASH player of CD image. The only thing is still undiscovered is set of commands and statuses on control 4 bit bus.

I've got it. The CD track is kind of tape with 74/80/99 minutes of play, digitally. So, when it carries an audio data, there no need a perfect sync, so rough time coordinate is M:S:F format in subchannel. When they turn the audio CD to the data CD, there must be more accurate sync to the "tape". So,...

Anyway, what about capture data?
