According to the LASM bytecode reference, the Wait command waits for the "given
number of 10ms". And, "If the given number is negative, the command is
ignored."
I don't know if that is quite the same as a NOP but it's worth a try.
(several minutes go by)
task main()
{
CreateDatalog(20);
repeat (4)
{
AddToDatalog(FastTimer(0));
Wait(1);
AddToDatalog(FastTimer(0));
Wait(0);
AddToDatalog(FastTimer(0));
Wait(-1);
AddToDatalog(FastTimer(0));
Wait(10);
AddToDatalog(FastTimer(0));
}
}

Variable 0: 17889
Variable 0: 17890
Variable 0: 17890
Variable 0: 17901

Variable 0: 17930
Variable 0: 17931
Variable 0: 17932
Variable 0: 17932
Variable 0: 17943
This seems to indicate that Wait(0) and Wait(-1) are very similar in effect.

| Is there a NQC command that will translate to a simple nop bytecode? I'm looking for a way to do fine-precision timing, and frankly checking a timer takes too long. For very fine motor control, I'm trying to use sequences like: On(OUT_A+OUT_C); (...) (21 years ago, 5-Jan-04, to lugnet.robotics)
