 | | BrickOS motor port horrors
|
|
I was writing some simple programs to test out BrickOS last night, and had some really strange behavior. I hooked up a motor to port B and a rotation sensor to port 2. My programs were just testing out various motor speeds and positioning accuracy. (...) (21 years ago, 25-Oct-03, to lugnet.robotics.rcx.legos)

It seems to be not possible to use lnpd+liblnp with brickos-0.2.6.10. Is there a patch available to get the liblnp package to work? (21 years ago, 22-Oct-03, to lugnet.robotics.rcx.legos)
