An NQC library to enable a LEGO RCX to send Visual Light Link (VLL) commands to a LEGO MicroScout.
When sent, the MicroScout will respond directly to these commands by executing them.
port: set to the RCX output port where the light source for sending VLL
is attached; either OUT_A, OUT_B or OUT_C.
MsInit(port) - Initialize communication.
Run this once before starting your first commands, and again if
MsOff() has been used and you want to start sending new commands.
MsOff(port) - Turn off communication
MsFwd(port) - Motor forward
MsRev(port) - Motor reverse
MsStopMotors(port) - Stop motor
MsBeep1(port) - Play beep 1
MsBeep2(port) - Play beep 2
MsBeep3(port) - Play beep 3
MsBeep4(port) - Play beep 4
MsBeep5(port) - Play beep 5
MsRunScript(port) - Run a previously programmed script (see below)
MsDeleteScript(port) - Delete a previously programmed script
A sequence of up to 15 of the following commands can be sent to the MicroScout, which will together form a script. The MicroScout will subsequently execute them when pressing the “run” button or sending it the direct command MsRunScript().
port: set to the RCX output port where the light source for sending
VLL is attached; either OUT_A, OUT_B or OUT_C.
MsScriptFwd05(port) - Run motor forward for 0.5 seconds
MsScriptFwd10(port) - Run motor forward for 1.0 seconds
MsScriptFwd20(port) - Run motor forward for 2.0 seconds
MsScriptFwd50(port) - Run motor forward for 5.0 seconds
MsScriptRev05(port) - Run motor reverse for 0.5 seconds
MsScriptRev10(port) - Run motor reverse for 1.0 seconds
MsScriptRev20(port) - Run motor reverse for 2.0 seconds
MsScriptRev50(port) - Run motor reverse for 5.0 seconds
MsScriptBeep1(port) - Play beep 1
MsScriptBeep2(port) - Play beep 2
MsScriptBeep3(port) - Play beep 3
MsScriptBeep4(port) - Play beep 4
MsScriptBeep5(port) - Play beep 5
MsScriptWaitLight(port) - Wait until the light sensor detects a light source
MsScriptSeekLight(port) - Turn on the motor if a light source is detected
MsScriptCode(port) -
MsScriptKeepAlive(port) -
Include rcxvll.nqh in your NQC program, then the Ms commands can be used. Example program using direct commands:
#include "rcxvll.nqh"
task main()
{
MsInit(OUT_A); // Lamp attached to Output A
//move motor forwards and backwards once
MsFwd(OUT_A);
Wait(20);
MsRev(OUT_A);
Wait(20);
//now produce all five beeps
MsBeep1(OUT_A);
Wait(150);
MsBeep2(OUT_A);
Wait(150);
MsBeep3(OUT_A);
Wait(150);
MsBeep4(OUT_A);
Wait(150);
MsBeep5(OUT_A);
Wait(150);
// Always turn off the lamp when done, to save batteries.
MsOff(OUT_A);
}
