But I still do not know what the limitations are and what the requirements are.
I researched a little, but I still have many doubts.
The best I found was this:
http://arduino-esp8266.readthedocs.io/e ... eadme.html
But still not clear enough.
In this link it says that in memory should have enough space for the old program and the new program. so I can only use up to 50% of my storage space for programs? The maximum is 1044464 bytes. (Arduino show)
500k of SPIFFS is enough to save the data of my application.
I take it to take another question that relates to this:
I use the arduino compiler and it gives me the option of:
Flash size "4M (1M SPIFFS)"
Flash size "4M (3M SPIFFS)"
What's the difference between them? I did not observe change when I changed.
