  NXT-G/ROBOTC Firmware Scheduler and Clump Priority
 
In a typical operating system (OS), tasks are scheduled on a priority basis. The highest priority task always executes ahead of lower priority tasks. If there are multiple tasks at the highest priority, then they are typically executed in a round (...) (17 years ago, 6-Sep-07, to lugnet.robotics.nxt)
 
  RE: Ooops! NXT Software Comparison correction
 
(...) After tuning, NBC achieved 73K test cycles. It achieved these great results by setting the task "priority" to 200. Unfortunately, unless the NXT-G task scheduler has been rewritten, these results might be a little too high. A NXT-G task (or (...) (17 years ago, 6-Sep-07, to lugnet.robotics.nxt)
 
  RE: Ooops! NXT Software Comparison correction / I2C Messaging Speed
 
(...) Nobody cheated or is dishonest. Everyone who writes firmware for the NXT is well-intentioned "good" people. Let's not mislabel good modern programming practice -- i.e. hardware device drivers integrated into the low-level firmware -- as (...) (17 years ago, 6-Sep-07, to lugnet.robotics.nxt)

(...) I think I understand. In this case, the limiting factor is the US sensor itself, how fast it can ing and interprete a return. Or from my standpoint (a physicist), it's a fundemental limitation of the physics of sound, not a limitation that has (...) (17 years ago, 5-Sep-07, to lugnet.robotics.nxt)
 
  Re: US-Sensor I2C-address
 
(...) To my knowledge the LEGO Ultrasonic sensor does not support changing its I2C address. IIRC it is hard-coded to 0x02. I do not think it is ADPA-compliant. John Hansen (17 years ago, 5-Sep-07, to lugnet.robotics.nxt.nxthacking)
