(...) indeed, the construction of this beast may be very different (e.g. metallic contact, 0 resistance... and a lot of bounce almost completely avoided with conductive rubber) Philo (21 years ago, 19-Jun-03, to lugnet.trains, lugnet.robotics.rcx)

No, I'm sorry, it doesn't seem to quite work. But it does get rid of the 3 errors at the bottom - Now it's just the operator new/delete stuff. I replaced the stub.c with the thing below, made libc++.a, and just make in lib/c++, and then go to demo (...) (21 years ago, 19-Jun-03, to lugnet.robotics.rcx.legos)

Thanks Philippe, I wasn't sure of the characteristics of the Cybermaster touch sensors. Also, I didn't want anyone thinking it was OK to use this guy: (URL) checking the resistance (yeah, I know it looks different, but you never know... :-) Mark (...)

(...) All touch sensors I measured have a "pressed" resistance between 400 and 600 ohms (depends on touch sensors and on pressure, more pressure meaning lower resistance). Actually there is no separated resistor, you get the internal resistance of (...) (21 years ago, 18-Jun-03, to lugnet.trains, lugnet.robotics.rcx)

(...) You should add -fno-rtti -fno-exceptions to the CXXFLAGS in Makefile.common. To get rid of the operator new/delete errors you can replace lib/c++/stub.c with a stub.cpp containing the following. Don't forget to update the Makefile. This works (...)
