 | | Possible bug in firm0328 or NQC 2.2
|
| Yesterday evening I was testing some NQC code for an RCX with the new firm0328 installed. A very strange thing happened: motor B was running when motor A was expected to do. I double checked the connections, and the code, and couldn't really (...) (24 years ago, 12-Jan-01, to lugnet.robotics.rcx.nqc)

| | Re: is IR considered broken?
|
| (...) I have working IR code, but it does not work with LegOS. It works with that "custom, as-yet-unreleased version of Librcx" I mention every so often. It probably wouldn't take much to port it to LegOS. Changes would be: - modify hook to get a (...) (25 years ago, 16-Jul-99, to lugnet.robotics.rcx.legos)

| | is IR considered broken?

| The precompiled tm-and-ir, kinda works for me. It is pretty good at receiving data, but the transmitted message often has garbage. When I compile it myself using the latest legOS snapshot, it always transmits garbage, others seem to have seen the (...) (25 years ago, 12-Jul-99, to lugnet.robotics.rcx.legos)

| | Joystick function in RCXCC

I guess it would be possible using the spirit.ocx (a directx control (...) (24 years ago, 1-Jan-01, to lugnet.robotics.rcx.nqc)

There have been reports that the existing code works for some, and not for others, so you may need to customize this. just (...) (25 years ago, 20-Jul-99, to lugnet.robotics.rcx.legos)

You can write programs in NQC (also in RCX Code or Robolab) that respond to IR Messages. These messages can be sent from another RCX, (...) (25 years ago, 13-Jul-99, to lugnet.robotics.rcx)

| | Re: Help with 9738 LEGO Mindstorms Remote Control

| Dave's reply is right on the mark, but I also want to point out that if you have downloaded a non-MindStorms O.S. to the RCX (i.e. any firmware other than the standard LEGO MindStorms firmware) the remote might not work either. I haven't tried any (...) (25 years ago, 12-Jul-99, to lugnet.robotics.rcx)

| Hi Kekoa, Could you post your working IR .srec code or email me if possible? I have tried the examples with the LegOS read sensor routines and I still get the same results. i.e. it works at about 2mm from the unit but fails after more than 5mm. I (...)
