I've just posted (URL) note that there are 4 other patches lingering from as far back as September. Will my patch be looked at because it has been posted there? For info, here is the patch description The last version of binutils that brickOS works (...) (22 years ago, 14-Jan-03, to lugnet.robotics.rcx.legos)

This was a terrific analysis. It's not surprizing that current implementation hogs so much CPU time. If all four A/D channels are scanned every 150 us then the A/D interrupt is occuring every 37.5 us since each A/D channel generates its own (...)

If one builds a fast moving robot, main concern will be how fast the robot reacts to light sensor changes or how small the structures could be that the light sensor will "see". If one builds a thinking robot, for (...) (22 years ago, 14-Jan-03, to lugnet.robotics.rcx.legos)

Mark, ANOTHER great find! You are pushing BrickOS to new heights! Ok, so what can we do about this? 1) Provide a constant to set the update frequency at compile time. 2) Provide a variable to set the update frequency at run time. 3) Optimize the (...)

Oops, found a little bug. ;-) Forgot to turn off the rotation sensors. Caused a wrong reading if you let the program run through the readings more than once. The rotation sensor section should read like this: // with two rotation sensors enabled (...) (22 years ago, 14-Jan-03, to lugnet.robotics.rcx.legos)

Hi All, The recent posts about interfacing an i2c device to an RCX sensor port (in .robotics) got me interested in looking at the kernel code that handles the sensors. So, I did and found myself looking at the ds_handler function. This function is (...) (22 years ago, 14-Jan-03, to lugnet.robotics.rcx.legos)

I have successfully built an h8300 cross compiler for DJGPP using the newest version of gcc 3.2.

So far I have heard from two people who have successfully used brickOS with BricxCC. I'm interested in whether anyone else has tried using BricxCC to edit/compile/download programs to brickOS. Currently BricxCC requires that the cygwin bin directory (...) (22 years ago, 8-Jan-03, to lugnet.robotics.rcx.legos)

Investigating into this further, apparently from the comments in CVS, a change was made to the makefile in legOS\boot (Rev 1.2) and legOS\demo (Rev 1.2) some three years ago. The comment stated "replaced makedepend by MAKEDEPEND". But no similar (...) (22 years ago, 6-Jan-03, to lugnet.robotics.rcx.legos)
