Find out the Revision of the ESP32 Chip

[Kazuya91]

Hello,

I want to find out the revision of my ESP32 Chip. I know that there is a prepared Arduino function which you can run. But I dont use the Arduino library. As far as I know the Revision number is stored in a register somewhere but it can be damaged if the coder does something wrong. So I wanted to ask if there is a fail safe code for non-Arduino-users.
