 | | Re: JVM and spirit.ocx
|
| (...) I don't exactly know how _much_ has been done, but I know there's been quite a bit of interest at times over the past year, and I know of at least three Java/JVM efforts related to the RCX. Here are some links which you might find useful: (3 (...) (25 years ago, 9-Nov-99, to lugnet.robotics.rcx.java)

| | Re: rcxhttpd?

| | Re: Deleting Programs

| (...) I created a user space program which does some of this. I call it "inspector" as it mostly inspects the values of sensors. It also shows the current battery reading and how long the RCX has been on. The UI is pretty simple to use. It also (...) (23 years ago, 25-Mar-02, to lugnet.robotics.rcx.legos)

| No, it's not documentation for pbFORTH - yet. I have found a decent book on line, it is Tim Hendtlass's Real-Time FORTH book. It is really geared for FPC, a dialect that is available for the PC, but the sections on numbers, stack manipulation, (...) (25 years ago, 13-May-99, to lugnet.robotics.rcx.pbforth)

| Ingore the message where I wrote that the RCX didn´t start. It started without showing the "4th" on the lcd screen. Does anyone know how to do that? I mean that when you press the "ON - OFF" button it beeps and shows the "4th" or something. Just so (...) (24 years ago, 21-Mar-01, to lugnet.robotics.rcx.pbforth)

| | Syntax for reserving variables in NQC?
|
| The fact that in RCX2 the counters are overlapped with global variables has brought about an interesting problem. How should a programmer indicate to the NQC compiler that a certain RCX variable location is to be left untouched (not assigned to any (...) (24 years ago, 28-May-00, to lugnet.robotics.rcx.nqc)
