Hi, I wonder if anyone may be familiar with the spec about the nxt brick: I found this on the ww.hobbyengineering.com . NXT Brick * 32-bit ARM7 microcontroller * 256 Kbytes FLASH, 64 Kbytes RAM * 8-bit AVR microcontroller * 4 Kbytes FLASH, 512 Byte (...) (16 years ago, 13-Feb-08, to lugnet.robotics.nxt)

| | Re: NXT Power Programming > LDD files?
|
|
(...) I don't know if the instructions are on-line (publishers don't always like that), but you might want to have them build something similar of their own, just to help in designing something. Remote controls tend to be pretty simple (although (...) (16 years ago, 27-Jan-08, to lugnet.robotics.nxt)

| | NXT Power Programming > LDD files?
|
|
Yesterday, I acquired and am sharing John's book "NXT Power Programming". I tried to read as much of it last night. Great book! Anyway, I'm at PSU conducting a Lego NXT class with 7 boys. Several of the kids are very interested in the Remote Control (...) (16 years ago, 26-Jan-08, to lugnet.robotics.nxt)

(...) Confirmed. The arrows and grey button share a common resistor ladder and only one can be detected. But the orange "on" button has an independant circuitry and can be used separately. See keypad schematics in the HDK. Philo (16 years ago, 21-Jan-08, to lugnet.robotics.nxt, FTX)

Can someone confirm that the front panel buttons on the NXT are wired in such a way that it does not work to press two of them at once? Not too surprising, I suppose, just as early computer keyboards were pre-decoded to signal which single key was (...) (16 years ago, 21-Jan-08, to lugnet.robotics.nxt, FTX)
