UT 01: Using EEPROM

This example shows how to use the EEPROM memory of Waspmote

Required Materials

1 x Waspmote 1 x Battery 1 x MiniUSB wire

Notes

- WARNING: Reserved EEMPROM addresses below @1024. 'Utils.writeEEPROM' do not let the user to write below this address. Do not try to write below this address as you could over-write important configuration. Available addresses: from 1024 to 4095 - This example can be executed in Waspmote v12 and Waspmote v15
