 | | new release???
|
| Hi, I've been wondering why there hasn't been put out a newer release than 990330, especially since the rotation sensors doesn't work in it. But the error was identified way back in April by Mario Ferrari ((URL) STATE_0_VALUE (ds_unscale(1023U)) ... (...) (25 years ago, 26-Aug-99, to lugnet.robotics.rcx.legos)

Compare those two light sensor readings: if the second is much greater than the first, there's something (...) (18 years ago, 7-Aug-06, to lugnet.robotics.rcx.robolab)

Here are some lines of code: (I think it's in lnp.h) #include <sys/lnp.h> ... clear_msg(); ... if (msg_received != 0) my_message_value = (...) (21 years ago, 8-Dec-03, to lugnet.robotics.rcx.legos)

| | advice for game of tag?
|
| Hi, I've got 2 bots that I want to play tag with each other. The challenge is that I want them to see each other at a distance. I'm working on some code to combine the IR ports with the light sensors (which can detect IR) as follows: 1) each sends (...) (24 years ago, 3-Feb-01, to lugnet.robotics.rcx.nqc)

| | Re: OO programing in RCX
|
| Thank you, David. Your gode is great! I learned a lot from your quick example, though I prefer Java more. I will encapsulate RCX commands in some utility objects and use them in more higher level objects. What I focus now is make a RF/IR adapter to (...) (25 years ago, 12-Jan-00, to lugnet.robotics.rcx)

Might the problem be caused by wrong versions of gcc or (...) (21 years ago, 28-Jul-03, to lugnet.robotics.rcx.legos)

You could write software which directly uses NQC to send messages to the RCX (since it supports the standard IR message feature in the RCX firmware. I have written a small (...)

I wrote a small test program that installs a lr handler function which simply displays the received key value on the LCD. But when running this and pressing (...)
