Re: Change an ADC from a mic to a line device

Big thanks guys, i will look on it monday. I read about the Bit Meter or Bit Sort on audiosiencereview. I havn't found a download. Good to know its now a plugin. Thanks. I have a similar ADC brand module here that calibrates with 1Vrms on the ADC inputs pins totally different in Arta as my but this ...

Re: Change an ADC from a mic to a line device

Hi Maxim, thanks for the hint. I suspected the mic input as a possible source of not going into the 32 Bit recording mode. In the xmos projects are to many declarations around all folders to find the right one. The constant UAC_TT_INPUT_TERMTYPE_xxx (usbaudio20.h) needs to be changed. I got it worki...

Change an ADC from a mic to a line device

Hello, i am just working to enable 32 bit ADC audio mode in windows 10. I added define STREAM_FORMAT_OUTPUT_1_RESOLUTION_BITS 32 in the costumdefines and -STREAM_FORMAT_OUTPUT_1_RESOLUTION_BITS 32 -Stream_FORMAT_OUTPUT_1_SUBSLOT_BYTES 4 in the makefile. I can't get it to work. Only 24 Bits are selec...

I need to switch four mclk oscillators.

Hello. i my application i need different selectable mclks 22, 24,45,49 MHz. I need the 45, 49Mhz set only to support 356kHz and above. XU208 TQ64 Problems is that the xmos audio software costumdefines.h have defines for only two mclks tasks. EG 45,49 MHZ /* Master clock defines (in Hz) */ #define MC...

XU208-128-tq64 with OTP set erase all ?

Hi, i have some older XU208 here . It seems that OTP is set. Xrun gives a Xcore 0 is not enabled message. Is it possible to reactivate the chips using an erase all command or do i have to send it to my garbage bin ? Because of lack of ICs i want to reactivate some for a new project if possible. I do...

Re: USB Audio framework spdif to i2s issue

Hi Florian, remove the PGA it will make it more worse. Then add a second OPA to the U404 and invert the output. You have the benifit of unbal to balanced analog inputs. Please use a long cap wire and wrap it around the top probe tip ground. You need shorter probe grounds to measure 24 Mhz. I am out....

Re: USB Audio framework spdif to i2s issue

Hi, it seems that you have a clocking issue. Please remove Ferrite Bead FB601 and replace it with an 4R7/10R resistor for better pll voltage filtering. Remove the 10uF C609 too. You need a stabe 24.0 Mhz clock on the xmos at any time. Please check. I use an XU216 but that doesnt matter because spdif...

Re: USB Audio framework spdif to i2s issue

Hehe you can wait here for an answer like me waiting for parts from xmos. A mess. Please have a look and resolder all pins and check if you have all clocks and voltages running. Maybe you have a cold pin. I wonder you have defined #define XUD_TILE 0 should it not on Tile 1. You have redefined the SP...

1 bit port write on tile 1 disables LRCLK

Hello, i have checked everything but i can't find the problem so maybe someone can help. If i write a high to an 1 bit port on tile 1 the lrclk X0D22 stops working. It seems that this 1 bit ports are used somewhere but the compiler gives no hints. The only one connected to tile 1 is mclk on X1D35 I ...
