Re: Sporadic "crosstalk" from I2C into TDM mic input when ports and SW on the same slice or connector

I added void set_core_fast_mode_on(void) in my mic PCM task (2.048 MHz) and did it get noisy! Yes! I don't think the sound even came through. What might the explanation be for that? p201 of xTIMEcomposer User Guide (Rev B) Sets the current logical core to run in fast mode. The scheduler always reser...

Re: Headset noise when printing

I now got the XScope output server to run. "Run XScope output server" ticked on, plus the stuff mentioned above. Strange, because I still get the strange sounds during printing, which I think is from the TDM inputs from mic or the headset, where the mic chip or the haadset DAC invent value...

Sporadic "crosstalk" from I2C into TDM mic input when ports and SW on the same slice or connector

I have struggled with some kind of sporadic "crosstalk" into my TDM mic pins: WS, SCK, but most "probable" the SD pin. (xTIMEcomposer 14.4.1) This is complicated to explain, but I'll give it a try. The result is simple : all fixed when I2C for the display was moved away form the ...

Re: Headset noise when printing

Thank you akp, thank you!

It might read 2024 before this is treated. A long thread gets longer, fine!

I am very interested to get this up and running! Very.

Re: Headset noise when printing

I wish I'd get this to work. But I don't. I use xTIMEcomposer 14.4.1 on a mac mini from 2010 on macOS Sierra 10.12.6 through a virtual screen on a newer machine. The 14.4.1 likes it there, no fuzz. I bought that old machine just for that usage. I was tired of fighting with outdated Java. I will proc...

Re: Headset noise when printing

Thanks for the response! I have experimented with xscope, but I did run the JTAG I/O server. If I tried your config.xscope and ticked the "Run XScope output server" in the debug config, I still got the clicks (which _might_ come from the I2C), but my debug window did not print a character ...

Re: Headset noise when printing

I now know more. If I turn all debug printing off then the rather long noises in the headset playback are gone. I don't know if this is because the XTAG 3 stops the cores or not. Now, when I write to the display through I2C at the same time, this is reduced to some times audible weak clicks. Writing...

Re: Headset noise when printing

Thank you! No offense in anything!

I'll follow this up when I know where the source of the problem is. Right now the pendula is moving towards the mic, not the headset.

Re: Headset noise when printing

Thanks, both. But no, I don't think it's a ground loop. I did have a scope connected, but I have an isolation trafo with it (NOT SMART FOR HIGH VOLTAGE MEASUREMENTS). However, disconnecting the scope and powering the board from a power bank did not help. What stops when XTAG does prints, by the way?...
