ESP32s2 Touch Sensor Application Question

I am in the middle of designing a hobby product that uses ESP32s2. The product is placed in an aluminium casing and I have a design-related question I would like to ask. I hope to learn something new based on the answers I find here. I would like to implement the touch sensor functionality without m...

Re: ESP32-S3 TensorFlow Lite Model Issues

Probably easier to figure out why things go wrong rather than looking at it as a black box and going 'it no work'. For instance: can you dump what the ESP sees on the audio input? Perhaps that's all 0 for some reason? Edit: Moving this topic to General Discussion as it doesn't have much to do with ...

Re: ESP32-S3 TensorFlow Lite Model Issues

The only thing regarding the memory that is printed out is the following message during every reset: "Loading model 12 bytes lost due to alignment. To avoid this loss, please make sure the tensor_arena is 16 bytes aligned. Used bytes 22644". I have not been paying attention to this (for now) as the ...

Re: ESP32-S3-EYE v2.2 - device not recognized by Ubuntu

Is the problem still present or did you solve it?

I face the same issue and it is not listed as "/dev/ttyACM*" either.

ESP32 .WAV file upload to Google Drive

I am trying to upload a ".wav" (circa 32kB) file from the flash memory of ESP32 to Google Drive. Is there a way to do that and would you be able to suggest a way to approach this? I am currently trying to use a code that does the same thing, but with ESP-cam images, and the encoding is very confusin...

Re: manually entering flash mode

Hello, I have the same problem, but the upload has worked until a few minutes ago, when it stopped. Now it doesn't let me upload and nothing helps.

Failed to connect to ESP32

Hello, I had been using an ESP32 DEVKIT V1 in my long term project which I need to work. The board didn't go into upload mode so I had to do it manually by holding boot button every time I uploaded a new code. I also used a small capacitator for some time between EN and GND pins. After some time (ar...

Hello, I had been programming ESP32, I had problems with connecting to the device, which I had solved by putting a capacitor between EN and GND pins. Everything had worked for month or something but today, when I tried to load new code for my long-term graduation project to test, the same problam ha...
