|
|
I've released BricxCC version 3.3.4.4. It fixes a timeout problem when trying to find the Cybermaster brick (although not all users experienced this problem). It also fixes some problems on the Color tab of the Preferences dialog. It fixes the (...) (23 years ago, 19-Mar-02, to lugnet.robotics.rcx.nqc)

(...) Definitely post it! Better than that, how about sending me the code and I'll add it to our robots section as a unique demonstration. (...) Shouldn't be a problem. Most of the source code in the official Sun package is easy to port to leJOS. (...) (23 years ago, 19-Mar-02, to lugnet.robotics.rcx.legos, lugnet.robotics.rcx.java)

(...) I'm not entirely sure why either, other than that it is extremely easy to add new language support to the editor component in BricxCC and I thought it would be cool if a user of BricxCC who also writes H8 assembler would be able to edit all (...)

(...) No rest for the wicked, John. (...) I always specify the size. Some assemblers can infer the size from the operand, but it's usually better practice to specify it.

(...) I just 'ported' (euphemism for minor modifications) some code lingering on the web for fun and voila: MD5 on RCX is up and running (lejos). If anyone's interested, I can post the code. It allows for authentication (PC sends random challenge, (...) (23 years ago, 18-Mar-02, to lugnet.robotics.rcx.legos, lugnet.robotics.rcx.java)

(...) This applies to the red 2x2 micromotor, not to the mini or power motor found in the RIS. I vaguely remember (try searching in LUGNET news) that the way to save a power motor, if at all possible, is to apply power in the right way, and not to (...)

I'm working on a syntax highlighter for H8 assembler for BricxCC. I downloaded a couple PDFs from Hitachi's website. I have the H8/300 Programming Manual (e602025_h8300.pdf) and THE INTRODUCTION OF HITACHI H8 MICROCOMPUTERS (introduction_h8.pdf). (...) (23 years ago, 18-Mar-02, to lugnet.robotics.rcx.pbforth)

Hi Chris, Thanks for the input. This is the kind of information I need. I have always relied on alcohol as a cleaner for contacts and I did not think of the effect it might have on the rubber contact. I thought the button might be a carbon contact. (...)
