No matter how hard I try - or how many different "this is how to do legOS under Win32" web sites I visit - I cannot get legOS and its associated cross-compiler to build. The stuff from brickOS dies during the make process because of "missing" (...) (23 years ago, 2-Oct-02, to lugnet.robotics.rcx)

|
|
Well, after browsing through the H8 reference another, oh 20 (?), times; and some messing around; it is now working. Basically, I had declared the Control Status Register as an 8 bit value. Since this is a special register (8 bit) that requires a 16 (...) (23 years ago, 28-Sep-02, to lugnet.robotics.rcx)

| | Watch Dog Timer on the H8
|
|
Has anyone been able to make use of the Watch Dog Timer on the RCX? The H8 documentation seems to spell out the workings quite well. BrickOS (LegOS) has minimal support (a vector is declared for both NMI and overflow) and pbForth files list the WDT (...) (23 years ago, 27-Sep-02, to lugnet.robotics.rcx, lugnet.robotics.rcx.legos)

Yes, the object is to have the RCX robot monitor its own battery charge (something available to the RCX firmware, and lejos, etc..) and then when it is consistently low to drive up to some sort of home made charging station and get a boost. The (...) (23 years ago, 26-Sep-02, to lugnet.robotics.rcx)

Hello, (...) The only problem with that is that you will have to guarantee a max. voltage of 9 or 10 V at the RCX. I don't think usual charging circuits have a voltage limit that makes sense ... Greetings Horst (23 years ago, 23-Sep-02, to lugnet.robotics.rcx)

In order to protect the RCX from any type of power problems, would it make sense to disconect the RCX from the batteries first and have it run from an alternate power supply? or would this make it too complicated? I know little about electronics, is (...) (23 years ago, 24-Sep-02, to lugnet.robotics.rcx)
