Hi, i'm trying to write a program that makes a Legoroboter able to navigate in different rooms / labyrints. For this the computer needs to know, when one of the touch-sensors is pressed. I use poll(9,x) for this. My problem is that the returned (...) (23 years ago, 7-Mar-02, to lugnet.robotics)

Hello again, I think I should have another go at this... I wanted to say "Check this out, I found an interesting application for the old pneumatic cylinders" What it came out sounding like was "Mr. Soh was wrong! Look at me prove him wrong!" Sorry (...)

Hi Bart, (...) if you mean LISTENER_THREAD then that sounds plausible. (...) Yes, LISTENER_THREAD has maximum priority, so it runs before any threads of lower priority, even yield doesn't help. (...) Yes, I think we'll have to fix that somehow. (...) (23 years ago, 6-Mar-02, to lugnet.robotics.rcx.java)

I'm re-posting this message at the lugnet.robotics.rcx level in case anyone missed it. I've put together a stand-alone application which I am calling ForthPad.

(...) The firmware downloader built into BricxCC is a port of Dave Baum's NQC code to Delphi. It calculates the checksum up to a length of 0x4C00. The limit of 0xCC00 is based on the sum of length + start (where start is = 0x800). John Hansen (23 years ago, 6-Mar-02, to lugnet.robotics.rcx.pbforth)

Experimenting with Lejos, two 'major' problems: memory (cleaning up platform & lang: Math.class is huge!) and... threads.

As an aside, I think it might be a straightforward matter to make emacs communicate with the RCX (or intermediary) and then you've got a full blown editor to work with (ie, there are already forth highlighting modes). (23 years ago, 6-Mar-02, to lugnet.robotics.rcx.pbforth)
