 | | Rotation sensors?

Hello, Rotation sensors appear to be broken in the 990330 snapshot. Here's part of the code I'm using: ds_active(&SENSOR_3); ds_rotation_on(&SENSOR_3); ds_rotation_set(&SENSOR_3, 0); while (!PRESSED(button_state(), BUTTON_VIEW)) { (...) (25 years ago, 20-Jul-99, to lugnet.robotics.rcx.legos)

(...) LOL! BTW, speaking of viruses (in the good sense) and on-the-fly bytecode compiling, do any of the RCX packages currently support the spontaneous exchange of high-level code between two or more RCX bricks? It seems like it would almost be a (...) (25 years ago, 19-Jul-99, to lugnet.robotics, lugnet.robotics.rcx.pbforth)

Allow me to request a little help from all the rcx experts out there. I've purchased Mindstorms set and the infrared remote control. As near as I can tell, I can not do what I want with the mindstorms software, so I'm hoping one of the alternative (...) (25 years ago, 19-Jul-99, to lugnet.robotics.rcx, lugnet.trains)

Thanks Dave. I hadn't downloaded the firmware yet. Originally, I was simply hoping to use the remote control and the rcx to drive my trains. So I didn't bother to install the software. Now I know.
