Great.
I’m glad the issue is solved.

Thank you for your very quick reply.
I must honestly admit that this problem could have easily been avoided afterwards
if I had first selected the ESP32 board in the Board Manager.
At that moment it was still set to Arduino Nano.
I found out this issue after going through the installation procedure you mentioned
(https://randomnerdtutorials.com/installing-esp32-arduino-ide-2-0/).
It also turned out that I had already performed that installation in the past.
Solved this (experiential) issue.

Hi.
The library FS.h that we use in this tutorial is included by default when you install the ESP32 boards in your ARduino IDE.
You don’t need to install any library.
Just make sure you have the ESP32 boards installed in your Arduino IDE: https://randomnerdtutorials.com/installing-esp32-arduino-ide-2-0/
And when compiling or uploading your code, make sure you select an ESP32 board in Tools > Board.

Let me know if you can solve the issue.

Regards,
Sara

Maybe a stupid question, but I can not find a good working library FS.h that is required for this tutorial. The only one I have found is at https://github.com/espressif/arduino-esp32 with file arduino-esp32-master.zip. When I click within the Arduino IDE 1 at Sketch-Include library-Add .zip-library and open the arduino-esp32-master.zip in the map Downloads then after opening I get the next error in the IDE 1:
“Specified folder/zip file does not contain a valid library”
When I unzip this file myself then I get after unzipping a map called:
“arduino-esp32-master” and in that map at /arduino-esp32-master/libraries/FS/src/ I find FS.h
On my disk at usr/users/usr/Documents/Arduino/ there is the subdir libraries and sketches. So I am wondering why the IDE 1 cannot place it there in /libraries.
If I try to install this zip file with the Arduino IDE 2 then the error is:
“Error: 13 INTERNAL: Library install failed: moving extracted archive to destination dir: library not valid”

I have tried it on a Windows10 Pc and A windows11 laptop. Both same result.
Maybe you may help me a bit further. Thank you.

Hi.
Yes.
I think that is possible, but unfortunately, I don’t have any resources about it.

Regards,
Sara

Do you think it is possible to program update from a SDcard to an ESP32 . I am working presently with arduino IDE.
Thanks

Hola Sara,
Logré resolver el problema, tenía un error casi imperceptible en una instrucción, casi me saco un ojo.
Muchas gracias.
Saludos,

Miller CM

Ya corregí el error de cálculo y logré que los datos en la memoria se guarden cada 5 minutos. Ahora tengo un problema: cada vez que se reinicia el ESP32 (o hay un corte de energía), el archivo en la memoria SD comienza a grabarse desde el inicio, es decir, se borran los registros ya grabados.

Qué debo hacer para que el archivo continúe grabando desde el último registro antes que se corte la energía?

Saludos,

Miller CM
