Hello, mon2! Deeply appreciate your contribution - you helped me a lot!!! Onto your points: 1) The STM32 is the master because it handles volume changes from the front painel IO and I'd rather implement simple communication between XMOS and STM32 about PCM modes than having the volume changes to be ...

Did you manage to get this working? It is very unclear on the XMOS documentation how to get SPDIF and USB Audio working on the same part.

Hello folks. I'm spinning the third prototype revision of a product I'm building - a stereo DAC device based on the XUF208-128-TQ64. I have read through a lot of posts and I think it is OK but, since I'm funding this and I don't want to end up with crap boards, would you mind helping me out checking...

Have you tried the Thesycon demo driver? Perhaps that's worth a shot prior to investing some heavy bucks into their full featured offering. I think it's a real bummer I have to go to a third party to get driver support for Windows. But again, it's also a bummer Windows USB Audio class 2 support sucks.

Given that piece of info, can you answer: without using lib_i2c, how are you supposed to share the i2c bus between multiple clients?

Regards.

You have a couple improvements you can make: 1) As mentioned, you can typedef interface LEDs_interface into LEDs_interface, then use: void LEDControl(server LEDs_interface); 2) If you are going to handle your interface to multiple clients, you have to allow your server to handle multiple instances. ...

There are some global free statements, like the timerafter to set time, I'm not sure you can do that outside a function. I've just recently done the porting of lib_i2c to my project and usually you don't pass the port around, but rather the interface instance. Can you provide a bit more detail on wh...

Hello everyone, this is my first post. I'm designing a DAC based on the XU208, which I'd like to have: USB Audio Class 2 2 Channels Out DSD Support up to DSD128 (perhaps DSD256 in the future) SPDI RX In Control for the DAC Chip Volume controls (which control the DAC gain directly) (Future) I2C contr...
