And that's it! You've got an array of 16-bit signed samples that are good to go.
Can you tell me... those samples you end up with, are they R,L,R,L,R,L...

Or only L?

Thanks!

Interesting. Thanks for sharing. Does it support any specific microphone? Or we can use it with any microphone we want?
It has an onboard microphone.

It just needs a connection from its line out to a line in, to record or hear it.

Getting the device serial number from an ESP32-S3 using IDF.

Hello, I am using the ESP IDF with an ESP32-S3 devkit. How can I get the serial number of the device, programmatically, using IDF? Note that I did find this statement ( https://esp32developer.com/programming-in-c-c/system/serial-number ) that the esp32 does not have one, and that the MAC address sho...

Mimimum sample rate for I2S.

I am trying to debug some I2S code I have, and thought I would turn down the sample rate really low. But the ESP32 does not seem to support low bit-rates? Because if I set it to 2400Hz, the samples are clocked much faster, then when I set it to 2434 Hz? What is the lowest sample rate that the ESP32 ...

Re: Saving SSID+passwd after WPS procedure.

Ah, Ok, I managed to do this. You can access credentials (after connecting) as:

Code: Select all

WiFi.SSID();
WiFi.psk();
And I write them to flash, using the SPIFFS interface.

Saving SSID+passwd after WPS procedure.

I am running the WIFI/WPS Example on my ESP32C3U. While this does get me an IP address, and makes my μcontroller ping-able on my network, I would like to store the result of the WPS on the device (I am using the M5Stack STAMP-C3U μcontroller.) NOTE: I use the push-button on my router to connect. Any...

Re: ESP32-C Device stuck in a boot loop: SHA-256 comparison failed

Hi @bstolk afaik GPIO6 to GPIO11 are normally used for flash. So yes, like @GregP72 already wrote, use different GPIOs for I2C. Thanks Felix I am confused... I am not supposed to use GPIO6, GPIO7, GPIO8, GPIO9, GPIO10 and GPIO11 for anything? Doesn't that severely hamper the usefulness of this boar...
