xk-evk-xu316 to xk-voice-sq66

[Mohassira]

Hi ,

What is the best way to connect the xk-evk-xu316 to xk-voice-sq66 ???

What do you mean by connect? Do you want them to be on the same xConnect network, or do you just need to send some clocks and data?

For the former you will potentially have some issues as the only available xlinks on the SQ66 (60 pin package) are a single 2-wire link and that is being used for xscope on this board.

Hi , Thank you for your reply , I am trying to use the SQ66 as microphone array and receive the processed sound into the XK-EVK-XU316 for further processing , I am trying to connect the J6 Header on the SQ66 , but wires to xu316 , I am connecting the SQ66 J6 BClk,Lrclk,data 1 to the XU316 Bclrk,Lrclk,Adc_dat pins , is that possible , my project is basically Voice Command Home Automation , so I am trying to capture the voice using the SQ66 as Microphone array and move the processed voice to the Xu316, is that Duable???

Yes, it sounds like you are doing everything correctly, but you should add mclk to the list of signals you connect between the two.

I would also ensure that the firmware running on the xk-evk-316 is set up to receive from that "ADC" and that if the SQ66 is the bus master that the EVK is the bus slave (or vice versa). You might also check that both boards are using the same IO voltages for those pins. If they are not that is pretty easy to fix with level shifters, especially since all of these signals are unidirectional.
