Add EEPROMClass and examples (#1034)
* enchanced EEPROMClass * Added eeprom examles and modified partition * added eeprom class and extra examples * No changes * No changes * added eeprom class and examples * fixed typo * length() returns user-defined sector size * updated and annotated example

ESP32 eeprom_class example with EEPROM library
|
||||
|
||||
This simple example demonstrates using EEPROM library to store different data in
|
||||
ESP32 Flash memory in a multiple user-defined EEPROM partition (0x1000 or 4KB max size or less).
|
||||
|
||||
Install 'ESP32 Partiton Manager' ONCE from https://github.com/francis94c/ESP32Partitions
|
||||
And generate different partitions with 'partition_name'
|
||||
Usage: EEPROMClass ANY_OBJECT_NAME("partition_name", size);
|
||||
|
||||
Generated partition that would work perfectly with this example
