(...) The motor outputs give a square wave of 1/8 up to 8/8 of a cycle. You can use a counter running at 8x the cycle frequency to measure how many eighths the output is giving, and light an LED accordingly. For the magnetic sensor, I suggest (...)

(...) We have worked with a big chart with black crosses on a white wooden surface. This works pretty well, since with the reflection of the light of the LED, black and white can be easily recognised. Then the ambient light has not a big influence. (...)

|

I would like to be able to drive one or two banks of 7-8 LEDs off of the motor ports on the RCX. I know that there is a winker board that senses the motor level to determine what pattern to display. Can this be accomplished otherwise? I also want to (...) (20 years ago, 7-Jun-05, to lugnet.robotics.rcx)

(...) Neither of these work, although the second one does introduce a temporary for everything except for the 0 part. It will result in the display sometimes showing a value of zero. NQC tries really hard to use as few variables as it can so you (...) (20 years ago, 5-Jun-05, to lugnet.robotics.rcx.nqc)

(...) Thanks for the ideas! Actually these yielded some interesting results: a = 0 + ((x * 100) + y); occasionally yielded 0 (as expected), but never yielded anything other than 0 and the correct value (that I saw). a = ((x * 100) + y); and a = (x * (...)

(...) You may be able to work around this by using parenthesis (untested). a = ((x * 100) + y); or you might try a = 0 + ((x * 100) + y); John Hansen (URL) (20 years ago, 5-Jun-05, to lugnet.robotics.rcx.nqc)
