 | | Communication between two RCX

I have two RCX. I would like to use the first one to download PbForth (and other forth programs) to the second one using the infrared port. Is there a way to do this? Thanks Mario (20 years ago, 13-Nov-04, to lugnet.robotics.rcx.pbforth)

(...) Not exactly. What NQC allows you to do is set one of 8 patterns of pulse width modulation (PWM) for an output. So for instance the highest power level is "always on" (9V for 100% of a cycle), while a lower power setting is a mixture of "on" & (...) (20 years ago, 7-Nov-04, to lugnet.robotics.rcx.nqc)

Hi all, I have some questions about controling RCX motors using NQC. I am using Lego 43362 motors. As I understand it has maximum RPM 219 at 9V In NQC I see that I can st the speed of the motors at 8 different stages. I can not find though how the (...)

(...) Thanks Dave. I didn't notice the RCX2 option in Bricxcc, works great now! Just to clarify, the only difference between RCX 1 & 2 (from the compile target POV) is the firmware it's running? ROSCO (20 years ago, 30-Oct-04, to lugnet.robotics.rcx.nqc)

(...) My guess is that NQC hasn't been told to target the 2.0 api, so it is defaulting to 1.0 which does not have SetUserDisplay(). See (URL) for a more detailed explanation. Dave (20 years ago, 30-Oct-04, to lugnet.robotics.rcx.nqc)

I can't seem to get SetUserDisplay to compile. When I compile my program, it gets "Error: undefined function 'SetUserDisplay'". I thought it might be the version of NQC (3.0a1) so I downloaded 2.5r3, but same error. Seems strange because (...) (20 years ago, 30-Oct-04, to lugnet.robotics.rcx.nqc)
