  • \$\begingroup\$ Etch the plastic top off, make holes in the passivation layer with an E-beam and start probing. (humm, maybe I should turn this into an answer...) \$\endgroup\$ – Oldfart Jan 11 at 11:47
  • \$\begingroup\$ The point of the lock fuse bits is to lock the device. You need to hack the device to read the code. \$\endgroup\$ – Puffafish Jan 11 at 12:24

If you are asking, "How can I recover a program from an AVR microcontroller when the fusebits are set to protect the code?" then the answer is that you can't. That's what they are for.

  • \$\begingroup\$ You can't easily but there are ways to get around those limitations, but the effort required is often not worth what you get. \$\endgroup\$ – Arsenal Jan 11 at 14:27
  • \$\begingroup\$ ... but if you have the resources to undertake that effort, you certainly don't need to ask how. \$\endgroup\$ – Brian Drummond Jan 12 at 17:04
