 | | RE: ARM Assembly Language Programming on NXT? —
|
| | | Do a Google on "LEJOS OSEK". I believe this is a solution that has taken the base "OS" from the NXJ JAVA byte code interpreter as the basis for programming the NXT using GCC C++. I assume if you can use the GCC C/C++ tools with the NXT then you (...) (17 years ago, 8-Oct-07, to lugnet.robotics.nxt.nxthacking)

| | | | | (...) Thanks Dick for intruducing LEJOS OSEK, When we develolped LEJOS OSEK, Prof. Mizuno wrote several GCC assembly code to port TOPPERS OSEK (an open source OSEK OS) to NXT.

| | | | Hi T.C., (...) I have an AT91SAM7S-EK here, it has 4 LEDs and 4 touch buttons. It should also be fairly easy to write a driver for one of the serial ports (polling would suffice for a start). On the NXT the only I/O that is easy to use with the (...) (17 years ago, 14-Oct-07, to lugnet.robotics.nxt.nxthacking)

I was not familiar with the NXT, so currently I'm looking at the on-board capabilities. I realized after some (...) (17 years ago, 16-Oct-07, to lugnet.robotics.nxt.nxthacking)
