I believe any data source (not just timers/sensors/variables) can be used in SetUserDisplay. The big limitation is that local variables cannot be used since the display is updated in a global context independent of the tasks. If you know of data (...)

Oops. Looks like a bug in the NQC API file. I just fixed the bug in the NQC source, but it's not major enough to warrant a new release yet. In the meantime, you can add the following lines to the top of of your source file as a work-around: #undef (...) (22 years ago, 8-May-02, to lugnet.robotics.rcx.nqc)

Hopefully this isnt a silly question. Does anyone know how to covert a float to an integer? It doesn't appear that the function atoi exists. Michael. (22 years ago, 7-May-02, to lugnet.robotics.rcx.legos)

No, the RCX knows nothing about the diodes. That is why devices like the light sensor only send a current signal in the range 0 - 0.32mA back to the RCX. This current then creates a voltage drop across the 10k reference resistor with respect to the (...) (22 years ago, 7-May-02, to lugnet.robotics.rcx.legos)

SetUserDisplay does not work like that. You need to specify either a sensor, timer, or global variable. Once you have done that it will continuously update the display as the value changes. In your case you should write your program something like: (...) (22 years ago, 6-May-02, to lugnet.robotics.rcx.nqc)
