The BBB is still said to available from february 24th. If so should arrive within 1 or 2 days from shipping.nige2000 wrote:i can see an array of i2s configurations appearingAleg wrote: Nah, clock issue is already solved :hide:
On the BBB there is a master clock signal available that could be used for clockless DAC-boards to work in a synchronised way.
The DIYINHK board can have a local oscillator mounted to act as a clock for the DAC chip in an asynchronised way and you could also use an external masterclock card for that purpose.
I also read in the BBB SRM that the clock pins on the processor are both input and output, and that would open up the option to use a separate masterclock board to synchronise both the BBB and the DAC from the same external source, so with a better clock and/ or a different oscillator frequency than is mounted on the BBB itself. The oscillator on the BBB can be switched off from software.
So plenty of options to try out.
BTW. I ordered two DAC boards from DIYINHK, where one is modified to carry an onboard oscillator and the other is unmodified.
They shipped this morning, so now sit and wait when they will be delivered. Which gives me time to think about the PSU for the boards.

when do you expect the BBB
think diyinhk delivery takes about 2 weeks
they also have 3.3v/5v low noise regulators in stock too
ive got one here somewhere ill try that at some stage
I also ordered a low noise 5V/3.3V regulator from DIYINHK, as it is the fastest way for me to have good quality regulator available.
I still have some PCB's for even better quality linear regulators, but just haven't got time now to get round to it. Besides that I don't have all components yet.
Cheers
