I see a discrepancy between the quickref page in the micropython website and the ESP32-WROOM datasheet.
In the ESP-32 quickref page: https://docs.micropython.org/en/latest/ ... ckref.html
I can read in the "Pins and GPIO" section:
In the datasheet from the Espressif site https://www.espressif.com/sites/default ... eet_en.pdfPins 6, 7, 8, 11, 16, and 17 are used for connecting the embedded flash, and are not recommended for other uses
I can read in the section 2.2 Pin Description - page 4:
Same is reported in the pin table before this text.Pins SCK/CLK, SDO/SD0, SDI/SD1, SHD/SD2, SWP/SD3 and SCS/CMD, namely, GPIO6 to GPIO11 are
connected to the integrated SPI flash integrated on the module and are not recommended for other uses
So it seems that pin 16 and 17 are not among those reserved by the embedded flash.
Which is correct?
Thanks for help
