Hi Dick, (...) that is all less than crystal clear from the AT91SAM7S data sheet, but plausible. (...) I think so, too. On page 2 at the left there is the circuit which generates VCC3V, and it is controlled by the AVR via P_EN. The 1.8V for the core (...) (19 years ago, 30-Nov-06, to lugnet.robotics.nxt)

| | Date/Time Clock for NXT?
|
|
A date/time clock would be a useful addition to the NXT. Naturally, it should continue to operate even when the NXT is powered "down". So here's a question for any hardware gurus that have a good understanding of the NXT schematic. The ARM processor (...) (19 years ago, 30-Nov-06, to lugnet.robotics.nxt)
