Re: F2P Forth

You can find a tutorial about using an open source PIC Forth (not mine) at http://tutor.al-williams.com. The compiler runs in GnuForth and cross compiles for the PIC -- very slick.

Re: Which Micro Controller to Choose?

There is such wide support for the PIC it is hard to go wrong. Be sure to read http://tutor.al-williams.com for some tutorials.<p>However, as some have pointed out its architecture is a bit strange. Many people prefer AVR or other processors that are not as oddly architected. However, there is less ...

Re: SUGGESTION!!! LARRY READ THIS!!!!!!!

Check out the Basic Stamp FAQ at http://www.wd5gnr.com/stampfaq.htm. <p>You'll find info about books there (click on Resources or search for Book). I need to edit some of the links on that page though. I wrote one that I like -- you can get it cheaper from Amazon which is why we no longer sell it di...

Re: Electronics Simulation Software

The Rser represents the series resistance of the source. It is illustrative to set it to 0 ohms and see what a mess you get on the plot! In real life, a source always has some series resistance and to get the best simulation you have to take everything into account.<p>I wanted to make that example s...

Re: BIOMATION (Gould) K105-D Analyzer Pods

Hi Rick. Is this the one with the centronics plugs in the front or the D connectors? I have one of these (the one with the centronics plugs) and I have the pods (although I would not part with them). I do have the manuals and there is a schematic of the pod (basically a TTL to ECL converter). I can'...

Re: pic ICE

The Microchip ICD is documented on the Microchip Web site and several people have rolled their own with varying degrees of success. Do a Web search for Microchip ICD and you'll find plenty. You might also search for ICD at PICList .<p> Olimex sells an ICD "clone" assembled for a low price. I haven't...

Oddly, they looked like they were framed -- as though the guy had maybe written an article in those two issues or something.

CSI - N&V

Did anyone else spy the N&V on CSI last night?<p>There they were on the mantle in the robot guy's house (helps to have TiVo). Looks like one was the current issue, but I didn't recognize the one on the right.

Re: Stamp 2 & LCD

I thought that code looked familiar!<p>OUTA is P0 to P3, OUTB is P4 to P7, OUTC is P8 to P11 and OUTD is P12 to P15.<p>The E and RS pins are defined near the top. Ground R/W.
