Actually, its not a general programming question. Efficiency of something like events is heavily dependent on the operating system (in this case the Lego firmware). Efficiency of "if" vs. "switch" can be very dependent on the compiler and the CPU (...) (24 years ago, 31-Mar-01, to lugnet.robotics.rcx.nqc)

Thanks for the information so far. Is there any NQC command similar to the RCX-code "wait until message"-block? --Tobias (24 years ago, 30-Mar-01, to lugnet.robotics.rcx.nqc)

I have been currently working on a control program that necessitates the highest reaction time possible. Does anyone what the fastest control statements would be using NQC (making the outputs react to sensor values as fast as possible)? i.e. Which (...)

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 (...)

Hi Tobias, this could look something like this for example : int global_message; // place to store and read messages for every task task main() { start Read_Messages; // start Receive_Message Task while(true) { switch (global_message) { case 1 : (...)

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 (...) (24 years ago, 29-Mar-01, to lugnet.robotics.rcx.nqc)

Hi Dean, thanks for your interesting idea for a reduction of transmission time. I will deal with that as soon as possible. Your questions: (...) Version 2.0 (...) No. Do you think that is faster?

Hi Marco, it is always interesting how many other people in the world do have the same problems or are dealing with the same subject.

Hi Bernd :) I see we're working in the same subject here :) *great* If you care to browse lugnet.robotics old thread "VLL *input* for RCX/CyberMaster (in NQC) ?" or the newer one, starting with "CM-RCX" (the subject had some variations) Your (...)
