Re: custom XMOS board not working with AN00129

Assuming your code is setup correctly for I2C, if SDA and SCL are always high, then perhaps your pull-up resistors on those lines need to be changed? The code you linked does not include the module where your main () function is located or at least I didn't see it. I suggest you look at main() and v...

Re: custom XMOS board not working with AN00129

Have you checked the power supply sequencing and your clocks are behaving as expected when connecting to USB? Start with page 23 (section 13) for power supply sequencing and verify your timing looks acceptable. Go ahead and post screen shots from your scope if you can: https://www.xmos.ai/file/xe216...

Re: custom XMOS board not working with AN00129

Have you verified the power supply sequencing and clock frequencies are correct? I don't see the full circuit in the image you sent. Would be useful to see your full power supply and clocking circuit with the CS2100. After that you might verify the connections from your diagram reflect the same pins...

Re: function dsp_filters_fir, coefficients parameters

Besides the array going out of bounds, I wonder how your program is structured - are you blocking an audio task while coefficients are being computed? You might try offloading coefficient creation to a parallel task and then only sending them to your DSP task when they have been computed.

Re: play music to avb endpoint in xcore-200 Kit

Windows does not provide support for AVB like macOS. I think the easiest way would be to come up with some sort of USB/thunderbolt interface with an AVB connection. The problem lies in that you would need (if memory series correct) the Intel 210 chipset, which would need some sort of AVB to ASIO dri...

Re: Connect xe216 and adau1452 to an arduino.

Sure, I've used XE216 and ADAU1452 together. Is the mega 2560 necessary though? Could you just do whatever microcontroller functions you need on XMOS? Also XE216 only has one USB Interface.

Ross - can you give any sort of update on this? Will it be targeting toward the xcore.ai kit?

For anyone else having this issue (am I really the first to try to build on Apple silicon?) here is the reccomended work around: First, you can force CMake to build the x86 host app by adding the following line to the top of the file examples/freertos/device_control/host/CMakeLists.txt: set(CMAKE_OS...

XCORE SDK Install on M1

I'm trying to get the new xcore.ai explorer board going and following the XCORE SDK install steps (https://www.xmos.ai/documentation/XM-01 ... stallation) but am getting the following errors on M1. Is M1 supported?

Re: SOLVED: Problems negotiating with xs1-u6a-64-fb96-c5

Glad you found a solution! Also check the Github as that usually has the most recent revisions for the libraries.
