The Mindstorms RCX Code software does the exact same thing as the code you listed, the only caveat is I think RCX Code uses power settings from 1 to 8 while NQC uses 0 to 7. Both result in the same bytecodes for the RCX to interpret. // turn A on (...) (25 years ago, 23-Jul-99, to lugnet.robotics.rcx.nqc)

| | Re: NQC emulator?
|

The idea has cropped up from time to time, but nobody has written one yet. You probably don't want to simulate NQC code, but rather interpret the bytecodes emitted by the NQC compiler. These are just the bytecodes of the standard Lego firmware. (...) (25 years ago, 23-Jul-99, to lugnet.robotics.rcx.nqc)

| | NQC emulator?
|
|
Hello, it seems that the LegOS people have an emulator so that one can test programs "virtually", i.e. on your PC rather than the real RCX. Is there something similar available on the NQC side?

But how does the original mindstorms software do it. With the Mindstorms software you can set the speed of each motor and it is obviously different. I must be missing something. I did a search on lugnet and found some NQC code to drive the motors (...) (25 years ago, 22-Jul-99, to lugnet.robotics.rcx.nqc)

The RCX uses pulse-width modulation to control power to the motor. The pulses are between 1ms and 8ms of power during an 8ms interval. In theory, this would result in different power being provided to the motor. The problem is that the motor has an (...) (25 years ago, 22-Jul-99, to lugnet.robotics.rcx.nqc)

I think that output power effects the modulation of the motor power. The motor power cycles on and off with the off time being longer at lower power settings. As David stated, this results in the same speed of the motor when it is unloaded for all (...) (25 years ago, 21-Jul-99, to lugnet.robotics.rcx.nqc)

I've had the same result. It seems an **unloaded** motor always runs at full speed. To explain it to myself, I've theorized that the 'p' (power) in Fwd() and OutputPower() is more akin to force and does not directly control velocity. Waiting for (...)

Okay, need some more help. I have the following code running. My expectation is that the speed of the motor would increase but the integer value in the 'Fwd' command doesn't seem to make any difference. The motor always runs at full speed. (...) (25 years ago, 21-Jul-99, to lugnet.robotics.rcx.nqc)

Has anyone figured out a way to utilize the buttons on the joystick? like maybe control another motor on top of the bot to turn an arm or something like that? -- Clay Aucoin (25 years ago, 7-Jul-99, to lugnet.robotics.rcx.nqc)
