  Declaration of kernel_critsect_count
 
kernel_critsect_count is declared volatile in kernel/critsec.c, but without the volatile keyword in include/sys/critsec.h - this upsets gcc3. Please could these declarations be reconciled? Thanks, Max. (22 years ago, 15-Feb-03, to lugnet.robotics.rcx.legos)

  How could I tell if I'd cooked the motor controllers ?
 
We had an informal Robo-Sumo thing at my work place tonight and I'm wondering if I killed my RCX. My 'bot had two gearmotors on A and two more on C to drive the wheels. Could they have drawn enough current when the 'bot was stalled to harm the RCX ? (...) (22 years ago, 14-Feb-03, to lugnet.robotics.rcx)

  Re: no long range IR from laptop says Lego
 
Kindly offline I am informed: yes indeed, some laptop designs have been seen to support less than half of the specified 500mA max load for USB bus power. I wonder how many mA the USB IR tower does need. Pat LaVarre (22 years ago, 12-Feb-03, to lugnet.robotics.rcx)

  no long range IR from laptop says Lego
 
Does the Lego USB IR tower, when set to long range, sometimes draw more than the 500mA allowed? Or do laptops generally not reliably supply 500mA?
