Re: Custom Board USB UART Pins ESP32-S3-Wroom1
I have pretty much the same problem, and I have been waiting for a reply for so long and still nothing yet. I'm designing a custom board, I referred to datasheet and reference manual, but couldn't find much about the pinouts of the ESP32-S3. Although the ESP32 is very popular, it is still surrounded...

Re: Custom Board USB UART Pins ESP32-S3-Wroom1
I have the same situation and I would like to confirm it before designing my own board. So, a USB<>UART bridge chip is not necessary to program/debug ESP32-S3-WROOM modules? So, IO19/IO20 are directly available as OTG USB? And what about VBUS? IT seems ESP32-S3 doesn't implement VBUS sensing.

ESP32-S3 - KORVO, audio related...
I was wondering what is the advantage of using the external ADC, ES7210, in the KORVO board. And as far as I can see, there are no line-level inputs on the board, like those you find on LyraT board. What I'm concerned about is the handling of audio input and processing and the peripherals involved, ...

Re: Using two I2Cs simultaneously - ESP32-S3
If you're referring to the fact that you don't see specific i2c pins; like a lot of ESP peripherals, you can route the i2c signals of any of the two i2c peripherals to any pin; in ESP-IDF, the I2C driver initialization will allow you to specify which ones you want to use. The ESP-IDF driver has sup...

Re: Using two I2Cs simultaneously - ESP32-S3
By the way, why everyone out there is referring to the entire ESP32 family as a "dual-core" while only a few variants, like the ESP32-S3, ship with dual-core units? For example, I was under the impression that all the ESP32-WROVER-B modules feature a dual-core chip, but I just realized that most of ...

Re: Using two I2Cs simultaneously - ESP32-S3
Yes exactly, that's what I was referring to. So, basically these are available as GPIO-mapped pins through the ESP-IDF? What about the Arduino Platform?

Using two I2Cs simultaneously - ESP32-S3
According to specs and many pinout charts for ESP32-S3 modules/DevKits, these modules offer two I2C peripherals, but I couldn't find any reference to the second I2C on any of these modules. Even on the KORVO board, the same I2C seems to be used across all peripherals available on the board (codec, C...

Trying to get my head around Espressif SDK for ESP32...
Hello everyone! I started with an ESP8266 few months ago and I've been able to build certain projects that involve most of the popular libs/stacks. I used PlatformIO with Arduino Platform. At the beginning, I had no idea what Arduino is and since I'm coming from a pure embedded C environment, I was ...

VoIP Example, missing headers...
Hello, I've been trying to build the VoIP example, https://github.com/espressif/esp-adf/tree/master/examples/advanced_examples/voip , on PlatformIO. The main file includes the following headers, but I couldn't find any reference to these files anywhere around: #include "esp_sip.h" #include "g711.h" ...

Re: LyraT 4.3 board sound quality
As expected earlier, it was the re-sampling of audio data fed into the decoder. I have changed the sample rate of the original mp3 file to 48000 and now the playback quality seems fine. By the way, wav decoder also works fine!
