Hi Sebastian, (...) I don't know the schematics of that sensor interface, but I think it's basically a bad idea to drive a device that needs 30 to 50 mA from a powersource that can only output about 10 mA. I've experienced similar effects while (...) (21 years ago, 2-Dec-03, to lugnet.robotics.rcx.legos)

I have some emails concerning this somewhere. But you don't need these patches (...) (21 years ago, 6-Dec-03, to lugnet.robotics.rcx.legos)

Ok, I'll take a shot at it: 1) Make a new directory in the root BrickOS directory called pgm. 2) Copy the files config.h and Makefile from the boot directory to the pgm directory. 3) Copy your C files to the pgm directory. 4) Edit config.h (in (...)

		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)

		Re: Logging sensor data
(...) If you had not already decided to use LegOS/BrickOS you might have used Robolab, which has nice sensor data-logging utilities built-in. I show a sensor log in my project 'The LEGO Level' at (URL) It's very easy to set up. Jerry (21 years ago, 10-Dec-03, to lugnet.robotics.rcx.legos)

Mark, This is an interesting issue. Initially, after reading your post, I was thinking that it would be easy to add this support to BrickOS. Of course, this is only partially correct. For NON Task Manager builds (therefore no Program manager), it is (...) (21 years ago, 9-Dec-03, to lugnet.robotics.rcx.legos)
