|
|
In BrickOS 0.2.6.08, there's a minor bug where the LCD arrows misbehave when the motor direction is set to brake. I believe the intention is to turn both direction arrows on when the output is in the brake state. However, what happens is that only (...) (22 years ago, 4-Dec-02, to lugnet.robotics.rcx.legos)

One thing I can tell you is that you need to add c:\cygwin\bin to your path (autoexec.bat) Also, when you try to download a program, instead of just using util/dll try ./util/dll I'm sure John will have other suggestions.
