		Re: More than 1 integer in a data packet?
(...) I'm not a leJOS expert by any stretch of the imagination. But I think I can help. (...) That is not a correct understanding of the rcxcomm package API.

		R: SPIRIT.OCX and embedded visual tools for winCE
I have developed a framework of classes in C++ that encapsulates the the RCX and its communication either from serial and from usb port. The framework is based on a proprietary library of fundation classes by SYCO called G++ that can be freely (...) (21 years ago, 6-Jun-03, to lugnet.robotics.rcx)

		RE: The pain of communicating with the RCX
(...) Good. I'm glad your on-side so far :-) (...) You are right. I have found that getting a reliable connection is very dependent on ambient light, the voltage of the RCX batteries, and the tower itself. Try to use the tower in NEAR mode so that (...)

		malloc() bug found -- BAD MEMORY REGION :-(
It looks like it's not a bug in legOS, but in the RCX hardware: Memory from 0xfb80 to 0xfd7f is simply NOT WRITEABLE, or more exactly, always read as 0xff, at least on my RCX ! Try the following little test: // // memory test // #include <conio.h> (...) (25 years ago, 1-Mar-00, to lugnet.robotics.rcx.legos)

		Re: leJOS & BricxCC news

But it "would be nice" if it were implemented as a library or patch to an existing brick OS (...)

		Re: RCX packet format
Michael, It depends on what type of software you are running on the PC. If you are talking directly to the serial port (or USB port) on the PC side, then you don't need to adhere to any specific packet type, you can invent your own (if that's what (...)

		Re: Multiplexing 4 touch sensors on an RCX input port

		Re: Multiplexing 4 touch sensors on an RCX input port
I have done work in this area.

I chose R = 40.2K. This is (...) (21 years ago, 10-Sep-03, to lugnet.robotics.rcx)
