Hi there, I'm quite new to the Mindstorms and LegOS/BrickOS scene but have recently begun using the kits for robotics purposes in University. They have been a revelation to me and speed up prototyping projects to no end. My question though concerns (...) (21 years ago, 9-Dec-03, to lugnet.robotics.rcx.legos)

(...) I just use the standard IR message stuff from BrickOS. They are normal messages, so this works just fine. Here are some lines of code: (I think it's in lnp.h) #include <sys/lnp.h> ... clear_msg(); ... if (msg_received != 0) my_message_value = (...) (21 years ago, 8-Dec-03, to lugnet.robotics.rcx.legos)

Hello, Anyone had problems getting the message 1,2,3 buttons working with brickOS? All other remote buttons are working. I am using v0.2.6.10. I looked through the kernel and includes, it looks like in lr_process(), the lr_keys gets checked vs. (...) (21 years ago, 8-Dec-03, to lugnet.robotics.rcx.legos)

(...) So, if I understand you correctly, your concern is that the OS tasks move around the first time you power off & on, but not anytime thereafter? Assuming this to be the case, then: 1) When you first download BrickOS, there is a large chunk of (...) (21 years ago, 7-Dec-03, to lugnet.robotics.rcx.legos)
