Neet on Protect My Data in Arduino Mega 2560

Projects Programming

Hi,

We are using this Arduino Mega 2560 in a small machine. We have uploaded the firmware. We are very keen to know how protective that data is. As i have come to know that data from one Arduino can be trasnferred to same Arduino card or the data can be leached through another external device or device. Please tell me how to encrypt that data so that its not used otherwise.

Use a programmer and set the Lock bits.

HI, MR CROSS ROADS
SIR CAN YOU TELL ME HOW TO USE PROGRAMMER AND BIT LOCK FOR ARDUINO MEGA 2560

First, don't post all over the place. One topic, one conversation.
Do you have a programmer?

And I think that after you load your sketch, you can use an avrdude command to change the lock bits. I don't know how to do that myself.
