26.7. Algorithm of error detection and correction ECC-DH

26.7.1. Overview

ecc_dh_example the example project shows the implementation of error detection and correction algorithm ECC.

• The error detection and correction algorithm of this project adopts ECC DH to complete the module encryption and decryption test.

26.7.2. Board Setting

• No special settings

26.7.3. Running the example

When the project runs correctly, and the serial port terminal will output the following information:
