How to lock ATMEGA328 and protect your hex code from being exported or saved using open programmer's oogui exe

[Kingsley Chukwuebuka]

hello everyone. I need a help on how one can lock atmega328 during hex code writing using opgui for open programmer?
I have a program i have invested much in and have finalised the successful completion. But i need to protect the code from unauthorised copy. Please anyone with idea of how to achieve this?

thanks in anticipation of your response...

Contrary to PIC devices, ATmega lock settings are not (currently) memory mapped on the hex file.
In order to activate lock you need to calculate the lock byte and write it using the device options.
