ESP32 WROVER - Lack of Photo Memory
Posted: Wed Jun 07, 2023 5:49 pm
Good afternoon everyone, how are you?
I'm using an ESP32 WROVER
I just need to put it on the network and take a picture (good quality)
In the description it says that the card has 4mb flash memory, but when I go to record it appears as follows Flash: [====== ] 64.5% (used 845098 bytes from 1310720 bytes) that is, it has only 1.3mb
A high resolution photo needs 1mb, but as it has no memory, it gives an error.
Follow my program
I was disappointed because I thought that this board would be able to take only 1 photo in good resolution. Is there still a way to do this? or would I need to buy the card that comes with space to put a memory card?
Thanks
