(...) Your request couldn't be more timely as I'm wrapping up a 0.2.6.10 test release this weekend. I've made this change in CVS and you will see it in the .10 test release. As I publish the 0.2.6.10 test release I'll post a message here explaining (...) (22 years ago, 15-Feb-03, to lugnet.robotics.rcx.legos)

| | 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)

I have the same problem (I posted a note 3 days ago "Problem with Brickos ..." # 20311). In addition I don't get firmdl3 to download the firmware. Are you running Windows or Linux? Hans (...) (22 years ago, 14-Feb-03, to lugnet.robotics.rcx.legos)

|

Hi, I downloaded brickOS 0.2.6 and patched it to use the USB tower. All works well (firmdl3 is patched correctly, the module goes in, I can make my own .lx files), except for dll. When I try to download a .lx file into the RCX, dll hangs. The LED (...) (22 years ago, 13-Feb-03, to lugnet.robotics.rcx.legos)

(...) I'd use a dual differential drive with (one motor fwd/rev, one motor turns) to ensure a straight line of travel and the a rotation sensor to measure the wheel rotations. If you don't have a rotation sensor use a light sensor to emulate one. (...) (22 years ago, 11-Feb-03, to lugnet.robotics.rcx.legos)

I'm not a professional or anything, but your idea could run into the robot pulling to one side, and not going the exact 1 meter. if you had two rotation sensors (not exactly RPM sensors), the error would be greatly reduced in both the distance and (...)
