 | | MacNQC can't open the #include file

When I have an #include line in my .nqc source file, such as #include "incl_file.nqh" the compiler complains that it can't open the referenced file. I get the following error: Error: could not open file incl_file.nqh test_file.nqc line 1 #include (...) (23 years ago, 9-Jan-02, to lugnet.robotics.rcx.nqc)

Hi all, The model this is written for is a biped walker with each leg driven by it's own motor. The PB is a Scout. It uses a modified version of ping.nqc to do IR proximity detection. When it detects that there is an obstacle, it should back up, (...) (23 years ago, 3-Jan-02, to lugnet.robotics.rcx.nqc)

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. You can also just do the following: until(SENSOR_1); Waits until it's touched. until(!SENSOR_1); Waits until the (...) (23 years ago, 17-Dec-01, to lugnet.robotics.rcx.nqc, lugnet.robotics.scout)

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)) (...)
