 | | Report on BrickHeap Wars: Robot Challenge #1
|
|
Ever since my brother forced me to watch an episode of Junk Yard Wars last year, I've been wanting to do something similar as a robot competition. BricksWest was finally an opportunity to try. I modified the concept slightly, to allow using LEGO (...) (23 years ago, 4-Mar-02, to lugnet.robotics, lugnet.events.brickswest)

| | RE: rotation sensors
|
|
(...) Yes, you need to read the rotation sensor continuously. Be careful to not read it TOO quickly, especially if the sensor is turning slowly or you get the jumpy count problem. There is a fix for it and I might add it too the rotation sensor code (...) (23 years ago, 4-Mar-02, to lugnet.robotics.rcx.pbforth)

(...) Keep digging. Try using a PC first and get that working. (...) Yep. (...) Sounds like pbForth is picking up steam again. Good. It's emails like this that keep me motivated to keep development going. I'm just back from a vacation, so I'll do (...) (23 years ago, 4-Mar-02, to lugnet.robotics.rcx.pbforth)

| | RE: h8/300 16-bit multiply
|

(...) The easiest thing is to cast your 16 bit values to 32 bits and use the built-in 32x32 multiply... Here's the code from pbForth that does it. (It's written in a pseudo- assebler, but you can probably figure it out...) #---...--- # UM* UM* ( u1 (...) (23 years ago, 4-Mar-02, to lugnet.robotics.rcx)

(...) John, This is great news! My own Tcl based GUI is a bit lacking, and a grand unified firmware uploader sounds like a great idea. I've been away on holidays and conferences most of the month, so I've missed most of this thread. Quick question, (...) (23 years ago, 4-Mar-02, to lugnet.robotics.rcx.pbforth)

| | Tip for cutting electric plates
|
|
To everyone, In case anyone has experienced as much trouble as I have attempting to sever the conductive strips in electric plates, I've posted the method I now use. (URL) a lot easier and a lot safer than severing with a knife and it doesn't mess (...) (23 years ago, 4-Mar-02, to lugnet.robotics)

(...) Exactly! (...) That's right! (...) Oh oh! Methinks you have not had the simple pleasure of playing with a hand pump (the new type of course) and an air tank like in the 8250 Submarine or 8462 Tow Truck or such like. Try it! (...) No need, just (...) (23 years ago, 4-Mar-02, to lugnet.technic, lugnet.robotics)

(...) I wrote a hack to dump all the words, and here's the result for version 2.0.0. The word list has changed since 1999. I think the list is complete, but no guarantees. ?DUP 2SWAP 2OVER 2DROP 2DUP RSHIFT DLShift LSHIFT MOD / * */ SM/REM /MOD (...) (23 years ago, 4-Mar-02, to lugnet.robotics.rcx.pbforth)

(...) My plan is to simply have the editor syntax highlight the built-in words in various (configurable) ways. Comments, for instance, () and \ would be highlighter in a certain way. Numbers in another. Standard Forth words that are not simple (...) (23 years ago, 3-Mar-02, to lugnet.robotics.rcx.pbforth)

(...) I'm also playing with interfaces to pbforth at the moment. What you're doing and I'm not is syntax highlighting. I'm not actually sure how well that works in pbforth, since I'm not sure how the editor knows which words have been defined (...) (23 years ago, 3-Mar-02, to lugnet.robotics.rcx.pbforth)
