Re: MIN_FREQ and DEFAULT_FREQ Ignored in USB Audio

Its possible. I'll have to look at the raw descriptor again and check which is making the change. Thanks for the help!

Re: MIN_FREQ and DEFAULT_FREQ Ignored in USB Audio

Where is this code found? I may be able to modify it to suit

Re: MIN_FREQ and DEFAULT_FREQ Ignored in USB Audio

I remember I tried digging through the code and I couldn't find any references to default or min frequency. Its almost as if those defines weren't implemented, but were put in for the future.

Re: MIN_FREQ and DEFAULT_FREQ Ignored in USB Audio

I take it no one has encountered this or is willing to test on their hardware

Re: How to add USB Serial port to XMOS Reference Audio project ?

Just tried this with a clean install of Windows 10 Pro x64 with all the latest updates. Using only Mario's uploads it worked immediately with no issues. Just in case someone finds this in the future, know that it still works flawlessly. You do need files from both posts though.

MIN_FREQ and DEFAULT_FREQ Ignored in USB Audio

Hi. I am trying to do UAC2 to i2s, which is working fine for the most part. I have included the following in my customdefines.h: #define MAX_FREQ (192000) #define MIN_FREQ (192000) #define DEFAULT_FREQ (192000) The max frequency changes properly, but when I change the minimum frequency and default f...

What do you mean? I am using this design to do i2s

Re: ‎XUF208 boot glitch

Yes that is. I am using it to generate the MCLK, There is a chance with this to be running it at some weird sample rates, so I wanted it to be adjustable. I don't think there would be any issue with that as I have had i2s working with that as the driving clock.

Re: ‎XUF208 boot glitch

SI5351A-B-GTR ‎ NCP303LSN30T1G R103 is 4.7 Ohms 1.07V and 3.39V (with my uncalibrated cheapo multimeter) The EN pin is strapped high with a 0 ohm resistor. That was put so I could inject a clock if necessary since this is a dev unit for us. In all the probing it booted up, so I can't probe it again ...

Re: ‎XUF208 boot glitch

Uploaded the wrong file, sorry. I reviewed the board integration section of the datasheet when I designed it, but it couldn't hurt to go over it again, I also assumed the dev board had the power sequencing right so I didn't check into it too hard. It is being powered via a SATA power connector. I wi...
