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);
Off(OUT_A+OUT_C);
I'm trying to run the motors at an effective slow speed, while still at a
reasonable power level. This works, but I'm wondering if I can goose the speed
up slightly with an effective nop or other single-bytecode command inbetween the
On & Off commands.

| (...) you may try something like this: On(OUT_A+OUT_C); On(OUT_A+OUT_C); Off(OUT_A+OUT_C); or if you're looking for speed control, you could try: if (speed>5) On(OUT_A+OUT_C); else Off(OUT_A+OUT_C); if (speed>4) On(OUT_A+OUT_C); else (...) (21 years ago, 5-Jan-04, to lugnet.robotics)

| (...) I think all of the single bytecode commands have side effects, which may or may not matter to you. You might want to use UnmuteSound(). Another option would be to create a command that does nothing. For example, a jump to the following (...) (21 years ago, 6-Jan-04, to lugnet.robotics)

| (...) 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 (...) (21 years ago, 6-Jan-04, to lugnet.robotics)

| (...) Here's a program that tries to analyze the various NOP options: #pragma reserve 0 __nolist void NOP1() { Wait(0); } __nolist void NOP2() { Wait(-1); } __nolist void NOP3() { asm { 0x27, 1 }; } __nolist void NOP4() { asm { 0x10 }; } __nolist (...) (21 years ago, 6-Jan-04, to lugnet.robotics)
