 | | New to PBforth - a few questions
|
|
Hello, I just installed PBforth and the associated GUI interface. It works great! However I do have a few questions to anyone who can help. If I type or just hit the enter key things seem OK. But after it sits for a few moments it gets junk on the (...) (24 years ago, 19-Jul-00, to lugnet.robotics.rcx.pbforth)

|

(...) And I would ike to say thanks! (...) The INCLUDE words are for the hFORTH scripts that this package is based on. I'm a terrible pack-rat, so I tend to put all the scripts in to give folks example code. It looks like I'm confusing things more (...) (24 years ago, 5-Jun-00, to lugnet.robotics.rcx.pbforth)

(...) I'm confusing everybody by asking questions that imply that I am changing existing code. I do not touch existing code. The question about where to enable the interrupt is a final cleanup one. It is not what I am doing now. I have not touched (...) (24 years ago, 5-Jun-00, to lugnet.robotics.rcx.pbforth)

I have been fiddling with serial interrupts with little success. Today I finally figured out that interrupts are masked in the CCR until you run the word RCX_INIT. I was blindly assuming that interrupts were generally enabled and I only had to deal (...) (24 years ago, 1-Jun-00, to lugnet.robotics.rcx.pbforth)
