(...) You had to turn on the lnp, with something like this: (I forget the exact commands) lr_startup(); lr_init(); lnp_init(); Make sure you turn it off: lr_shutdown(); Steve (19 years ago, 26-Sep-05, to lugnet.robotics.rcx.legos)

Hi Mindstormers, 1) Does BrickOS allow to write/read measured data into the RCX memory, in order to plot or process it later on the computer ? If yes, what are the command lines to : - allocate the memory space ? - to write and read ? - free this (...) (19 years ago, 26-Sep-05, to lugnet.robotics.rcx)

| | Swan scheduling bug?
|
|
I'm starting to use the swan firmware and I'm having a problem with the scheduling. It seems like a task with a long wait does not yield properly to other tasks. Here the NQC code sample: task taska() { WaitMS(150); AddToDatalog(9900); } task main() (...) (19 years ago, 22-Sep-05, to lugnet.robotics.rcx)

Palm 130, pbrick, rcx 1.0 Can the palm 130 with pbrick be used to control an rcx that doesn't have firmware downloaded? My suspicion is that it won't work without the firmware. Tammy (19 years ago, 22-Sep-05, to lugnet.robotics.rcx)

Thanks to your advices, Dick, Matt, and Steve, I've been very happy to solve my time sampling problems, installing BrickOS, which runs the rcx fast enough to get a proper position servoing (using rotation or light sensor, and a PID controller). I (...) (19 years ago, 20-Sep-05, to lugnet.robotics.rcx)
