Re: I2S-parallel example: Drive a 64x32 display
Yeah ordering that from Adafruit would be insane. However I like fine-pitched displays, but I only found this one which is too large and expensive: https://www.aliexpress.com/item/New-product-P1-667-indoor-smallest-pitch-full-color-module-360000dots-sqm-120-90mm/32751046497.html?spm=a2g0s.8937460.0....

I didn't get what hardware you were using. I suppose those aren't ws2812b LEDs because the display is "dumb"?

Re: ESP32 Webradio
I went on a Bluedroid SDK search, but it seems A2DP source mode is not implemented. You'll have to ask Espressif if/when they'll plan to support it. I agree it would be quite useful.

Re: I2S Receive bug causing garbage data?
Sorry, was quite busy. Just did a run quickly, not sure it makes sense. I took your code and only changed the pins.

Good to have you back, and thanks for the detailed explanation!

Re: What would you like to see in The Next Chip?
Well in theory we've already got PDM mode, but in practice nobody managed to eliminate the noise. @Espressif: maybe you can say something?pataga wrote: Also repeating what someone else mentioned - stereo true 16bit DACs to go with the i2s ! Drool. Not "sort of working" DACs but accurate 16bit DACs.

Re: Regulator ESP32 Deep Sleep
Mouser, Digikey, even Octopart don't know about HT7833. Where do you get them from?
