  • Awesome article. FYI: I think the PIC firmware seems tiny because the code protect bits are set (location 0x300008 is 0x00). With these bits set to zero, the ROM from 0x000800 to 0x007FFF will read as zero. And indeed, that entire space is filled with zero. Also, the reset vector begins with a branch to location 0x001ACA, which is all zeroes, so I'm pretty sure most of the actual firmware is missing due to the code protection.

No public wish lists :(
