  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)

  Re: The BrickOS Task Manager
 
(...) [snip] (...) Hi Mike, What version of BrickOS are you using? IIRC the correct type for thread IDs in the current version is tid_t, not pid_t. Also, I dunno if it was a typo, but you should include tm.h, not tm.c. HTH ROSCO (21 years ago, 5-Jan-04, to lugnet.robotics.rcx.legos)
