I got the latest version of legOS, and now I am lost. What else do I need to start programming? I know that the files I have aren't a program, but you download them to your RCX with your RCX program instead. Can anyone help me out? thanx (26 years ago, 15-Oct-99, to lugnet.robotics)

My suggestion is to double check that you double check the simple things withing the code (your code should be executing an infinite loop) while(1) { code .... } If the code is more complex and involves external assembly modules, check that they (...)

alex, each of your processes must be an indefinite loop. otherwise starting them up via start_process just runs through once. so, e.g.: void checkir() { while (1) { if (digital(4)) { /* go backward for some time */ /* turn a little */ /* go forward (...)
