 | | 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 (...) (18 years ago, 30-Nov-06, to lugnet.robotics.nxt)

In article <J9Jv4v.nDo@lugnet.com>, Dick Swan <dickswan@sbcglobal.net> writes (...) This question seems straightforward. In the hardware schematic PDF that Lego have published there is a block diagram of the "Power Block" on page 4. This does indeed (...) (18 years ago, 30-Nov-06, to lugnet.robotics.nxt)

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 (...) (18 years ago, 30-Nov-06, to lugnet.robotics.nxt)

(...) I think so too. One solution to the problem would be an I2C clock "sensor", such as MindSensor's (URL) one is not directly adapted to NXT, but if there is some demand it would not be hard to do... Philo (18 years ago, 1-Dec-06, to lugnet.robotics.nxt)
