| | Another little update to nxtgcc.sf.net: 1.05 compatability
|
|
Hi The 1.05 sources have been changed toward compatibility with a gcc-toolchain. To save rewriting, I take the liberty of pasting the contents of the readme file that you find in the root directory of the NXTGCC-0.0.10.zip file that can be (...)

| | Update to nxtgcc toolchain
|
|
I have updated the toolchain little bit: *the binsert utility reads binary file info directly from the standard firmware image (and you do not have to cut out the file sections manually) *the demo program executes, which is probably what some have (...)

Hi, Has anyone tried using the standard NXT Ultrasonic sensor calibration settings? I've been doing a little work on the leJOS i2c interface and although I can read both the factory default values and the current settings I do not seem to be able to (...)

Hi T.C. (...) aha. I just programmed some startup and interrupt wrapper code (the rest is C), so I didn't get into the higher reaches of macros etc. Jürgen (17 years ago, 16-Oct-07, to lugnet.robotics.nxt.nxthacking)

Hi Juergen, Thanks for replying. (...) Thanks for the info. My goal is to run and debug ARM assembly language programs executing in RAM. 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)

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)

(...) Thanks for the tip. I glanced at (URL) previously but I must've missed it thinking it's Java based. (...) Are you referring to the default NXT firmware or the LEJOS NXJ/OSEK firmware? (...) You're right, I've come across several ARM-based SBC (...) (17 years ago, 9-Oct-07, to lugnet.robotics.nxt.nxthacking)
