» RFID1356 08: Set low power mode

This program shows how to set low power mode in RFID1356 module

Required Materials

1 x Waspmote
1 x Battery
1 x Coin cell
1 x RFID 13.56MHz board
1 x RFID 13.56MHz antenna
1 x RFID Tag

Notes

- Remember to connect the battery to Waspmote for proper operation.
- Don't write address 0, 3, 7, 11, 15, ... if you are not an advanced user. You could leave your tag unaccessible.
- Address 0 contains the IC manufacturer data. This block has read-only access.
- Address 3, 7, 11 contains the secret keys A and B. Writing in them will change access keys and conditions.
- This example can be executed in Waspmote v12 and Waspmote v15
