To send a message use the following:
SendMessage(<variable> or <number>);
The variable must be of integer type between 1 - 255
The number must be between 1 - 255
To read a message from the IR port do
<variable> = Message();
This will put whatever number is in the message buffer into your <variable>
As to what to decided to send and get this depends on your code. Here is a
simple example. You have 2 RCX. RCXA and RCXB A will always send and B
will always recieved and respond via a light output.
code for RCXA (Note I am typing this out of the top of my head and have not
run it yet... also not going to show all the code (initaliazation, etc.)
TurnLight = 1; // Let RCX B know to turn on output 1 (Motor/Light on A)
SendMessage(TurnLight);
Wait(100);
TurnLight = 2; // Let RCX B know to turn on output 2
SendMessage(TurnLight);
...
For RCXB
while (true)
{
if (Message() == 1) // Got a message 1 in your buffer so turn on motor A
{
Off(OUT_A+OUT_B+OUT_C);
OnFwd(OUT_A);
}
elseif (Message() == 2)
.
.
.
}

| I can't figure out how to use the IR commands. I've tried, read a bit in the documentation, but still have no clue. I'd like to know how to: a) Send a message (and decide what message it should be) and b) learn how to recieve messages Thanks in (...) (23 years ago, 29-Mar-01, to lugnet.robotics.rcx.nqc)
