In the meantime I have identified the required IOs with a scope when generated signals:
IO2 = A13
IO4 = A12
IO5 = SS
IO15 = A10

Can anybody help where it is all written?

Then the problem is that I use wrong variant file. Where can I find the Arduino pinmap of the bare ESP32-Wrover-E? And which board should I choose at boards manager?

Well, I have investigated the issue, and it seems something is confused in the documentation or I have misunderstood something. So, when I have chosen the pin I wanted to use, I looked on the pin layout in the datasheet of the ESP32-Wrover-E. As an example let's see the IO15 pin of the device. Scope...

Hello Fellow users, I am trying to use the GPIO of an ESP32 in Arduino IDE. In a previous project this form of declaring the digital IO was good with an ESP32-S2: #define RESETPIN A19 Now with the ESP32 it is not working. I have tried the followings with no success: #define RESETPIN A19 or #define R...

Thanks for your reply and sorry for my late response. I haven't got e-mail notification of your reply.

Anyway. The -S2 package was not installed, you are right. The problem was that the IDE does not support installing the package directly, I had to copy the files manually.

Thank again!

Hi All, I have bought a Saola dev board (ESP32-S2-Saola-1MI) and I am trying to upload my first code into. I use Arduino IDE and when uploading the IDE fails to connect to the device: A fatal error occurred: Invalid head of packet (0x50) :( Reading forums it seems everybody have resolved this issue ...
