A few years back [Bunnie] took a crack at cracking the security fuses on a PIC microcontroller. Like most of the common 8-bit microcontrollers kicking around these days, the 18F1320 that he’s working with has a set of security fuses which prevent read back of the flash memory and EEPROM inside. The only way to [...]

Here’s a nice little discussion about reading and writing AVR flash memory that [Windel] put together. He’s using an In System Programmer to read the flash memory from an ATmega328 using AVRdude, the programming software which we used in our AVR Programming Tutorials. He covers the particulars of the commands, how this might be useful, [...]
