(...) Yep. But if I have two choices I will always steal from working code over documentation. I will always write code in C first and see what assembler the compiler creates, especialy on a new machine. Trust what already works. -- (...) (24 years ago, 22-May-00, to lugnet.robotics.rcx.pbforth)

OK I'm about to nervously take the plunge. My code assembles and I'm about to push it off the cliff and see if it flies. If any one feels bored please feel free to review the following and make comments. Finding bugs by inspection is always easier. (...) (24 years ago, 22-May-00, to lugnet.robotics.rcx.pbforth)

(...) Steve, You ARE using Kekoa's Internals document, right? Here's the part that describes the interrupt vector redirection. In fact, that's what I do for grabbing the OC1B interrupt for the servo control words... remember intercepting the (...) (24 years ago, 22-May-00, to lugnet.robotics.rcx.pbforth)

(...) As they say (with a striaght face in the original C library) "Use the fork, Luke" I hope you didn't find the M4 stuff too much of a brain-bender.

Yeah!! After lots of reading and study and experimentation and suggestions from Ralph I finally added a new word to the .asm files. It was a simple word. I just cloned DUP under a different name. But it works. Now I am truely turned to the dark (...) (24 years ago, 22-May-00, to lugnet.robotics.rcx.pbforth)

I think my problem is bounce back noise. I doubled checked the port settings, started with a fresh set of batteries, made sure I had a clear buffer, but what made the difference is where I am doing my programming. I'm working off of a laptop, and (...) (24 years ago, 20-May-00, to lugnet.robotics.rcx.pbforth)
