Firmware protection
Posted: Thu Jun 03, 2004 8:03 am

I have to send out my first baby. PIC 18F452@16MhZ. I have it programmed and ready. How can I keep others from reading my firmware and reverse engineering it. Will using a one-time-program chip help?? ie: How do I protect my code.

Read the data sheet section on fuses. It's all there.
