Enable this option will make the EEPROM use SPI1 pins, which is shared with the main
|
|
flash chip. Therefore, when doing transaction on SPI1 bus, data cannot be fetched
|
|
from the flash, so all the data used during this time should be put into the internal RAM.
|
|
|
|
Currently this example hasn't supported SPI1 pins on other chips yet.

Enable this option will allow the example to be blocked while the EEPROM is working
|
|
in progress, and unblocked by GPIO interrupt. Otherwise the example will keep polling
|
|
until the EEPROM is idle.

The Erase_All and Write_All commands of EEPROM are only supported when EEPROM is
|
|
supplied by 5V power. Enable this to use those two commands.
|
|
|
|
But please note that ESP chips don't support 5V IO, you need to add external
|
|
level-shifting circuits between ESP chip to the EEPROM.
