DSD Odd Output

Been working on a custom board using the XU216 and ES9068 DAC. All PCM works perfectly up to and including 768kHz. If I connect the board to a Windows PC and use Audirvana and WASAPI (not ASIO with Thesycon drivers) both DSD Native and PCM work perfectly. I confirmed that the I2S output from the XMO...

Re: XN file for dual XCORE-200-EXPLORER setup

I am very far from an expert but I took a quick look at your XN files and noticed that you moved the SPI flash definition from Tile 0 to Tile 2 <Device NodeId="1" Tile="2" Class="SQIFlash" Name="bootFlash2" Type="S25FL116K" Perhaps that has something...

Re: Hobbyist friendly XCORE-200 board

Re: Hobbyist friendly XCORE-200 board

I'll have to go back and flash the original firmware but I believe that it enumerated with just the XMOS VID and maybe a different PID. I've attached some other data that I gathered.

Would you mind providing some details on how I switch to using lib_i2s

Re: Confused on Port and Pin Assignments

So of course once you post something you find part of what you were missing. I see in audiohw.xc this definition: on tile[0] : out port p_gpio = XS1_PORT_8C; Which ties together the port assignment that I assumed before but missed. I guess I incorrected also thought that your port/pin assignments ne...

Confused on Port and Pin Assignments

I've got myself all confused while trying to study the audio example code (app_usb_aud_xk_216_mc). When I look at the schematic (xCORE-200 Multichannel Audio Platform 2V0 Hardware Manual.pdf) I can see: X0D26 DSD_MODE X0D27 DAC_RST_N ... X0D33 MCLK_FSEL X0D26:X0D33 are P8B or P4C/P4D If I look at xk...

Re: Hobbyist friendly XCORE-200 board

+1 on the DIYINHK board and they were available at least 1 month ago. Good luck getting any support from them. They respond to requests but provide no real information back. For initial testing what I did was mount the USB 4-pin header on the board and then plugged in a small 5V to 3.3V switching re...

If you install xTimeComposer there are many examples included in the IDE, the flashing LED example document is https://www.xmos.ai/download/XM-007385-AN-4.pdf
