I have been experimenting with the latest version of pbFORTH (102) Which announces itself thus: hhii hForth H8/300 for RCX RAM Model V1.0.0 by Ralph Hempel, 1998 All noncommercial and commercial uses are granted.

(...) Yes, I forgot to turn it off after first downloading the firmware, and getting called away to do something else. Luckily they were rechargeables... (...) Thanks, I'll try it. I will be spending more time with FORTH over the next few weeks, (...) (26 years ago, 4-Apr-99, to lugnet.robotics.rcx.pbforth)

(...) My next project is to port the IR proximity dectector originally posted by Mark R. David (markdavid@mediaone.net) in sort-of-Spirit code which I reposted in NQC whan I had got it working. It is the best performing detector I have found so far. (26 years ago, 4-Apr-99, to lugnet.robotics.rcx.pbforth)

| | TRACKER script for pbFORTH
|
|
Hi All, I've been a busy man while my spouse is off in Florida. I've been building and programming robots with my two sons, and have got the TRACKER to work! It's basically the same chassis as the TOP SECRET PLANS at the back of the Constructopedia (...) (26 years ago, 30-Mar-99, to lugnet.robotics.rcx.pbforth, lugnet.robotics)

(...) YES!!! The standard FORTH word U. prints an insigned integer, while EMIT sends out an arbitrary byte. So, for a simple IR proximity detector, you would write something like: HEX 0 SENSOR_ACTIVE (labelled sensor #1) 3 1 SENSOR_TYPE (light (...) (26 years ago, 30-Mar-99, to lugnet.robotics.rcx.pbforth)

Hi, is there any way to send IR messages using pbForth. This is in order to use the IR proximity detector commonly used with nqc programs. Also I think that with alternative firmware such as pbForth and nqc, it should be possible to do it without (...) (26 years ago, 29-Mar-99, to lugnet.robotics.rcx.pbforth)

| | Light Sensor Non Destructive Mods

Hi All, I've just added a new page to my website that describes a non-destructive mod to the light sensor that actually allows it to read ambient light! (URL) The range is <10 for a dark box and >90 for a halogen lamp about 6 feet away. It's really (...) (26 years ago, 28-Mar-99, to lugnet.robotics, lugnet.robotics.rcx.pbforth)

(...) Measuring PWM is not difficult, but it would involve a micro (PIC12C508 anyone?) dedicated to the task and then you would have to get it to drive the RCX, which means motor drivers, etc. If you are willing to spend $50 and LOTS of time, then (...)

Ralph, Thanks for reigning in the rabbit chase! As the originator of this thread I'd like to respond to the 'why'... I keep running out of ports on my creations. I see 5 or 6 as a practical limit. My criteria for a solution: 1. Entirely compliant (...) (26 years ago, 26-Mar-99, to lugnet.robotics, lugnet.robotics.rcx.pbforth)

(...) I have checked this out, and if you use the standard RCX firmware (or other firmware that uses the RCX ROM, then you get the waveforms you are talking about at 125Hz 1/(1ms x 8). You also get polarity information - oh no, I've said too much. (...) (26 years ago, 26-Mar-99, to lugnet.robotics, lugnet.robotics.rcx.pbforth)
