but in arduino, I not have option 8Mb.
I have only 4M (1M spiffs) or 4M (3M spiffs)
I do not understand what the right to program

- Wed Nov 25, 2015 5:50 pm #35006 Don't forget that 8Mb is 8Mbits, so it is 1MBytes ...
In such case, you have 4 choices in IDE menu.

- Thu Nov 26, 2015 8:00 am #35053 O now I understand. Thank you

I can choose to 1M and reserve space to store data as desired in spiffs?
