  Re: Events in robolab
 
(...) As part of some of our robotics outreach work, we have produced various materials that may be of use. Some of the stuff we have got round to putting on the web can be found at: (URL) particular in the resources section towards the end of the (...)

  Re: The BrickOS Task Manager
 
IIRC the issue was that Task, Process and Thread were all used to represent the same item/concept in the Kernel code. After some discussion, it was decided that the word Task would be used in all cases. This improves readability, etc... (ie. Task (...) (21 years ago, 6-Jan-04, to lugnet.robotics.rcx.legos)
 
  Re: Sensor Power
 
(...) Take a look at the functions ds_power_on() & ds_power_off() as defined in the dsensor.c kernel file. When you've set the sensor to passive mode, you should be able to manipulate the sensor power bits using these functions[1] or just use the (...)

  Re: RCX low battery indicator problem
 
(...) I've tried the RCX2 firmware (firm0328.lgo). Same results: after downloading the firmware the RCX beeps (low battery signal) and is locked. In BrickOS when I read the battery sensor and write it's value on the display it says 620 (mV, Ithink) (...) (21 years ago, 5-Jan-04, to lugnet.robotics.rcx)

  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) (...) (21 years ago, 5-Jan-04, to lugnet.robotics.rcx.legos)
