 | | Problem with IR
|
|
For some reason I'm having a problem downloading with NQC. I previously had the serial tower set up at the end of a track. The rcx on my robot goes up and down it. I used to have occasional problems with the IR comms, but I'd change the battery and (...) (19 years ago, 19-Nov-05, to lugnet.robotics.rcx)

(...) Different light sensors will produce different readings. The range of readings you get will also vary between different light sensors (for example, between the same white surface, and the same black surface, one light sensor might have a (...)

Hi, I have these 2 different light sensors. One reads "41" vs another reads "34" on the same area. I have troubleshoot it by switching ports, different RCX brick. The reading different stays the same. Is this reasonable because they might have a (...) (19 years ago, 14-Nov-05, to lugnet.robotics.rcx.robolab, lugnet.robotics.rcx)

Hi I'm experimenting with the Swan firmware but I have a puzzle.

You are missing semicolons after the: Wait(turn_time) lines (both) And a code suggestion, instead of: task drive() { while(true) { OnFwd(OUT_A); } } make it: task drive() { OnFwd(OUT_A); while(true) { } } as the motor stays OnFwd until turned off.
