		How is the battery doing?
Time to start a new thread I think. I eventually got my battery monitor working, constants from Kekoa: : .V BASE @ DECIMAL RCX_POWER [ HEX ] 4001 POWER_GET RCX_POWER @ [ DECIMAL ] 10997 390 */ 0 <# [CHAR] V HOLD # # # [CHAR] .

		legos application downlod protocol
Hi, I'm a developer for leJOS (a Java VM on the RCX) and I am interested in how legos applications are transfered from the PC to the RCX (basically because the leJOS mechanism seems to be fairly flakey and I'd rather not try to implement an entire (...)

		light sensor LED control
I'm using NQC 2.2 (but I also had the problem with 2.1) to compile programs for my RCX. I don't see how to control whether the LED in the light sensor is on or off.

		direct manipulation of bits in RCX registers using NQC
Hi all, Can anyone tell me if it is possible to use NQC to directly set bits in RCX registers? And if so, how does one do it? I've seen C code examples of this in a few places, but no NQC examples. Specifically, I want to turn on and off the red (...) (19 years ago, 12-Sep-05, to lugnet.robotics.rcx.nqc)

		Pullback RCX Car

		How to send button cmd or run pgm remotely from one RCX to another ?
I am trying to use lnp_addressing_write() or lnp_assured_write() to send commands (e.g. CMDdelete, CMDsethost) from one RCX to another. This seems to be the way it is handled in loader.c of the DLL utility. I am not having any success. Is there an (...) (21 years ago, 19-Feb-04, to lugnet.robotics.rcx.legos)

		How to user MONITOR command for watching TIMER in Spybotics
Dear Members, I managed to use NQC MONITOR command to watch TIMERs in my SCOUT using the predefined SCOUT events (EVENT_TIMER_0). However, I failed with my Spybotics and RCX 2.0.

(...) This can't be right. I'm about 99% sure that all of the ints I've used with my legOS programs have been 2 bytes. When using LNP to send RCX ints to a PC, for example, you have to use short on the PC end of things to make it all work right. (...) (22 years ago, 12-Jul-02, to lugnet.robotics.rcx.legos)
