It appears that the time has come for 0.2.6; it has been more than 18 months now since 0.2.5. I still lurk here, but my work with Free Software has consumed my time- even when I'm not paid, I'm pretty much a slave to bugzilla.gnome.org and (...)

I think it would be a very good idea to incorporate the prio-patch to legOS. But there seem to be a lot of patches and enhancements for 0.2.5. Personally, I use the remote control patch from Zhenrong Zang. And there is the TCP/IP system... Any more (...) (23 years ago, 9-Feb-02, to lugnet.robotics.rcx.legos)

| | Priority Interrupt Patch and legOS-0.2.5
|

We are gathered here to witness the union of priointerrupt-patch.diff and legOS-0.2.5. If anyone has just cause why these two should not be wed may they speak now or forever hold their peace. Robert Templeton (23 years ago, 8-Feb-02, to lugnet.robotics.rcx.legos)

Still no luck in getting the mux working properly. I tried making use of the code for turning sensors on and off but later realized that the ds_handler code would still be turning the sensor off as part of its normal operation. I think I'm going to (...) (23 years ago, 7-Feb-02, to lugnet.robotics.rcx.legos)

I've just uploaded a new release of BricxCC. Version 3.3.3.7 completes the implementation of the configurable Tools feature. Transfer item parameter macros are now functional. The major feature enhancement in this release, however, is the addition (...) (23 years ago, 6-Feb-02, to lugnet.robotics.rcx.nqc)

Now that my interest has been piqued by the multiplexer problem (and sensing problem in general), what would some of you hardened embedded/real-time system veterans recommend for reading on the subject. Two books that I've found at Amazon.com are (...) (23 years ago, 6-Feb-02, to lugnet.robotics.rcx.legos)

(...) I'm just checking this thing out. You can look at: (URL) more information. Unfortunately, I got the .ps description file but not the source code patch file. A mail asking for it is on it's way ;) Mike (23 years ago, 5-Feb-02, to lugnet.robotics.rcx.legos)

(...) Most people's legOS kernels will be compiled so msleep uses wait_event. I haven't looked at the code, but my understanding of how wait_event works is that whenever that thread becomes eligible to execute, your even function is called. (...)
