| Hello,
I tried that code and the behaviour is quite similar, if not the same. I'm starting to think that it can be the USB descriptor... maybe. I don't know. 0x05, 0x01, ... |

| This actually suggests the value _isn't_ 2's complement.
This was what was worrying PCMprogrammer about the notes he had found. A 2's complement 9bit value, can represent +255 to -256. However t ... |

Thats similar to what I tried to do, but your program is correct, and mine didn't work correctly. I still have one problem that I can't seem ... |

It's great, it has a pin that changes its state each second, connect that one to an INT_EXT pin, and you're good to go. Also you can get full date and time info by I2C. http:// ... |
