|

In NQC, I can use ClearTimer(0) and Timer(0) to get interval of time, how can I do it in legOS? I used t1 = sys_time, then t2 = sys_time, so interval = t2 - t1, is it correct? Zhengrong (23 years ago, 18-Dec-01, to lugnet.robotics.rcx.legos)

hi All, Inspired by some applications of the 16F84 PIC, we came up with the idea to make a IR-module, which is capable of doing all the InfraRed tasks we could imagine with the RCX. Well it hasn't come so far, but we have build a RCX IR-remote (...) (23 years ago, 17-Dec-01, to lugnet.robotics, lugnet.robotics.rcx, lugnet.robotics.rcx.nqc)

I was using my scout this past weekend as a coinbox detector to launch a mono rail. The touch sensors work exactly as Dave suggests.

This program turns on motor A and leaves it running until a touch sensor attached to input 1 is pressed, then it turns off the motor and plays a sound: task main() { On(OUT_A); until(SENSOR_1 == 1); Off(OUT_A); PlaySound(SOUND_UP); } Dave (...)

I've sort of solved my problem, but not in a way which really makes total sense. Both of the below fragments work as expectd: #1 if ((SensorValueRaw(1) & SensorValueRaw(0)) != 255) #2 if ((SensorValueRaw(1) != 255) || (SensorValueRaw(0) != 255)) (...)

Hi Richard, No, NQC does not implement any of the trig functions. However, you can do it yourself. The idea is to use a second order polynomial to approximate the sine function.
