XCore Exchange

Hi,

I am planning to buy "xCORE ARRAY MICROPHONE". I am very new to this board. Please help me.
I have couple of doubts related to board. Could you please clarify below doubts.

1. What is the output of the board? Can I receive audio data through USB?
2. what is the sample depth? (number of bits per sample)
3. what is the sample rate of output?
4. Is it possible to select each microphone? what is the control over microphone?
5. Can I use the USB for reading the data?
6. Is USB only for power or for reading output from board as well?
7. What is USB Audio Class 2.0 support?

Thanks,
Bhanu

1. What is the output of the board?

Can I receive audio data through USB?
Yes
2. what is the sample depth? (number of bits per sample)
32 bits from lib_mic_array
3. what is the sample rate of output?
48k->3k
4. Is it possible to select each microphone?
yes
what is the control over microphone?
?
5. Can I use the USB for reading the data?
Yes
6. Is USB only for power or for reading output from board as well?
Not just power
7. What is USB Audio Class 2.0 support?

Thank you Andrew !!!
I need more details. Could you please clarify.

1. What is the output of the board?
It has a DAC that outputs stereo over the headphone jack
<BHANU> Output can be through headphone or USB. Right?
<BHANU>This has 7mics, Will it output only stereo or 7 channel output? OR Stereo output for headphone jack & Multi channel output for USB?

2. what is the sample depth? (number of bits per sample)
32 bits from lib_mic_array
<BHANU> When I read the audio data through USB, Is it 32-bit data always or any other data depth(like 16-bit or 24-bit) ?

3. what is the sample rate of output?
48k->3k (Is it 3k or 384k?)
<BHANU> I read following statement "The system can be configured to generate PCM output at sample rates from 7.35kHz to 48kHz".
What is the difference between this sample rate and the sample rate provided by you?

4. Is it possible to select each microphone?
yes
<BHANU> How can I select microphone? Is there any physical button or some other way? Could you please explain more details.

<BHANU> Output can be through headphone or USB. Right?
<BHANU>This has 7mics, Will it output only stereo or 7 channel output? OR Stereo output for headphone jack & Multi channel output for USB?

7 mics transferred over usb, stereo audio output via USB to DAC.

<BHANU> When I read the audio data through USB, Is it 32-bit data always or any other data depth(like 16-bit or 24-bit) ?

This is configurable in the code

it looks like all the info you need is here: https://www.xmos.com/support/boards?product=20258

If you want to just connect to USB and use it as a 7 channel microphone then you can.

<BHANU> I read following statement "The system can be configured to generate PCM output at sample rates from 7.35kHz to 48kHz".
What is the difference between this sample rate and the sample rate provided by you?

Sorry I don't understand this question.

4. Is it possible to select each microphone?
yes
<BHANU> How can I select microphone? Is there any physical button or some other way? Could you please explain more details.

You could code this up if you desired, by default all mics are send via usb

Thank you Ross. I ordered board. Once I start working on board, I will ask more questions :-).
Once again Thank you very much.

Hi,

Today I have received "Microphone array evaluation board, xTAG debugger, USB cable-2".
Could you please let me know How to connect board and what is the use of xTAG debugger?
How to start with it?

Hi,

What are all drivers I have to install to connect board "XP-USB-MIC-UF216" to PC.
Any firmware is required?

Could you please explain me details about the process.
Along with detailed process, share the paths for software so that I can install the software which you are pointing to.

I have installed TUSB Control Panel, xTIME composer.

When I connected board to PC, TUSB Control panel was showing "No Devices Found".
How to resolve that?

My first experiment would be, Connect Board to PC and record mic's audio using Audacity.
Please help me to resolve issues.

Thanks,
Bhanu
