 | | Mindstorms NXT programming languages —Bruce Hopkins
|
| | | Hi all, One thing that was noticibly absent from the press releases was the programming language(s) that would be used for NXT robots. Since NXT seems to be an addition to the Mindstorms family (and not a replacement for the RCX) I would assume (...) (19 years ago, 6-Jan-06, to lugnet.robotics)

The Wired article mentioned some tidbits on this, including the it was sourced out to National Instruments; IMS they also had a hand in Robolab. It seems that it will be a graphical language... (...)

GCC already contains a backend for the ARM7 CPU used in the NXT (the tech specs on the lego page say its an ARM7) so, assuming TLC releases the hardware specs somehow (or someone reverse engineers them and figures them out which is quite (...)

But there is already a Linux port to the ARM7 - if the NXT has enough memory and some (...) (19 years ago, 7-Jan-06, to lugnet.robotics)

| | | | | | | | (...) A lot of people are saying this, but it's a bit off. The GameBoy had a Z80 based CPU; the GameBoy Advance has an ARM7. While the DS sports both, and uses the ARM7 to run GBA cartridges, a DS cartridge may well make use of both at the same (...) (19 years ago, 7-Jan-06, to lugnet.robotics)

| | | | | | Hi William, (...) I'm pretty sure the official language also uses a VM like on RCX and Spybots, so there you have your "massive overhead". Lejos is a good approximation of a Java VM in the RCX, and the NXT has 2 to 10 times as much memory depending (...) (19 years ago, 8-Jan-06, to lugnet.robotics)

| | | | | | | | Hi Brian, (...) On the RCX Lejos is about that much faster than the standard firmware, and we have 1ms timer resolution. (...) You also get those in Lejos, and compared to NQC it can access more memory. Jürgen (19 years ago, 8-Jan-06, to lugnet.robotics)

W.r.t. speed we are faster, but the standard firmware has a more uniform timing. (...) (...) (19 years ago, 12-Jan-06, to lugnet.robotics)
