Re: MADI (Multichannel Audio Digital Interface)

I'm revisiting this topic and would like to ask for help. Would you be up to try your best on MADI on a xmos board? My email is my username plus @gmail.com so you can contact me and we can discuss time and price. Could be a fun project during Corona time. Thanks

Re: MADI (Multichannel Audio Digital Interface)

It's been a while. I'm still interested in having MADI@XMOS. What is your opinion about it? Is it feasible?

Re: MADI (Multichannel Audio Digital Interface)

That's excellent news. I'm still on it. With some surrounding parts (which are needed anyways) it would be possible to keep it in the 100MHz clock domain. The extra 25 Mhz comes of the 4B5B encoding but some PHY's (mostly the optical transceivers) can do that internally. I have the VHDL code of a fu...

MADI (Multichannel Audio Digital Interface)

Hi XMOS libraries cover the majority of digital (multichannel) audio protocols which is great. One that's missing is MADI. Another one is DANTE but otherwise, it's pretty much covered. DANTE needs licensing which is PITA but MADI spec is fully documented. Considering the effort done for AES3 based p...

Re: Ethernet Slice on Square

Thanks. I was aware of the documentation but struggled over the smi. This is how I got it working: #define ETHERNET_USE_SQUARE_SLOT #ifndef SMI_COMBINE_MDC_MDIO #define SMI_COMBINE_MDC_MDIO 1 #endif port p_eth_rxclk = on tile[1]: XS1_PORT_1B; //XS1_PORT_1J on CIRCLE port p_eth_rxd = on tile[1]: XS1_...

Ethernet Slice on Square

Hi On a L2-Slice-Kit board, I managed to get the AN00122 (webserver) demo running. The port definition is correct for the CIRCLE slot. However, I would like to use the SQUARE slot and adapted the port configuration as much as I could but never succeeded. Based on an older (back in 2010) post somebod...

Re: sync clock to digital in - how to PLL?

Thanks. I'm not using the USB library. I take the samples from the adat_rx and send it to the I2S and want to clock to the digital in. Can I use the clockgen also for this?

Thanks.

leds and RGMII

Am I correct to say that the 16 leds on the xCore 200-MC show a nice pattern when using the RGMII Ethernet library because they actually share the port/pins? I mean there is no such thing as an led driving function in this library for something meaningful such as a basic visualization of the 16 core...

Re: I2s loopback and sending a ethernet stream

Thanks peter for the pointer to the frame_master which indeed relaxes serving the samples... it's working here! I also wanted to try the slave mode but as there is no sample I don't know how to set the codec's gpio and clocking system. couldn't find any example on this and the documentation just &qu...

Re: optical Rx and Gigabit: tile full

Thank to all of you! I got: - a reduced library of the RGMII - thanks to peters input! As I'm sending only and don't need any MAC functionality I guess it could even be stripped down further - but the library is too huge for me to fully understand. Maybe you have another pointer on where to remove c...
