Re: XMOS and AKM DACs

Review this thread to see if it helps: https://sourceforge.net/p/gcbasic/discussion/579126/thread/7fddc974/ I too had seen that the Si570 makes I2C communication difficult for itself and others, but my board is a 4-layer design and I've confirmed that things are working as they should. Besides the ...

Re: XMOS and AKM DACs

If the glitch appears before the XMOS signals a sample rate change, what controls the change? Host computer, hardware via arduino, or...other? I've used AKM DACs, ADCs and Codecs without problem, but mute and then change SR, as I feel that is good practice. I've yet to do some serious scoping of th...

Re: XMOS and AKM DACs

When set to manual mode, you need to reset it via the relevant register, which I am doing btw. It doesn't help. Problem is, the problem manifests itself even when the dac is in auto mode (so no reset is necessary), plus the glitch appears before the XMOS signals a SR change (I'm using combinations o...

XMOS and AKM DACs

Hello everyone, I've successfully designed and built a USB to I2S interface board utilizing the XUF208 chip, running firmware ported from the MC reference design following the relevant application note. I'm using it to supply I2S to a dual mono AK4490 of my own design (see: http://www.dimdim.gr/2017...

Re: USB Audio 2.0 support coming to Windows 10 from Microsoft

My XUF208 design works just fine with Windows 10's native UAC2 driver.

It's running XMOS' USB Audio IP ported from the XUF216.

Re: Standard UART Library - using in MC Audio project

Ok, this is extremely helpful but it still presents me with a steep learning curve. I don't mind, but I'd appreciate a couple of pointers regarding the concepts of client and server interfaces and the method that must be followed in order to pass them through the various functions. So far I've done ...

Standard UART Library - using in MC Audio project

Hi guys, new guy here. I'm doing a project involving an XUF216 doing USB to I2S duties. I've adapted the mc reference design project to my needs with no problems, everything seems to be working as it should, I'm getting audio out and everything. But then I attempted to include a UART interface and m...
