Im happy to see a Portuguese dude creating this type of content ... This is real tech youtube! Unlike many others in the portuguese that say they are "tech" youtubers but they only do unboxings and don't even do a proper review.

The esp32 C3 FH4 Has 4MB embedded flash memory acording to the datasheet. Does the eeprom library works with that too? And how to know the address ?
The same as the normal ESP32?

"text section exceeds available space in the board" how to solve this error

[kvamsidharvamsi]

this is about eeprom of 512 bytes, you are saving last state in eeprom not in flash memory, tell about flash memory, is flash memory = eeprom then 4mb = 512 bytes, obsoletely No, then how to program flashmemory

How do I loop namespaces for example np1 np2 np3 namespaces in preferences? I have been trying that for past week but can't seem to figure it out. It is also difficult because of how complicated it is. If anyone can, please help.
