  Sensor Power
 
ok, I have a real question. I'm interested in sending messages between RCXs using only the sensor ports. I've tested and found by switching between active and passive, signals can be sent, however, when the port is set to active, it is not powered (...)

  Motor Display
 
For some silly reason, I was browsing through the BrickOS code and I noticed this: void motor_a_dir(MotorDirection dir) { dm_a.dir = dm_a_pattern[dir]; dlcd_hide(LCD_A_LEFT); dlcd_hide(LCD_A_RIGHT); if (dir == fwd || dir == brake) (...) (22 years ago, 5-Jan-04, to lugnet.robotics.rcx.legos)

  nop in NQC?
 
Is there a NQC command that will translate to a simple nop bytecode? I'm looking for a way to do fine-precision timing, and frankly checking a timer takes too long. For very fine motor control, I'm trying to use sequences like: On(OUT_A+OUT_C); (...) (22 years ago, 5-Jan-04, to lugnet.robotics)
