Hello Bert, thanks.  The PICAXE 08M2 is 8 pins, same as a dual opamp.  and it has an internal resonator so all 6 pins apart from power can be used for I/O (with certain restrictions).

You CAN call your variables whatever you want, using a command, and I'll be dealing with that in Part 2.

I must look into QB64 though I have long had a hankering to learn Visual Basic.  Structured program people will tell you that the GOTOs in BASIC are a no-no, and I do make an effort to avoid them in general use, but there's times they save you a lot more jumping through hoops.   

I'd love to be a fly on the wall next time you are building something :-)

Pretty cool, David. You model picaxe looks only two pins bigger than a dual opamp.

Glad to hear you're a BASIC afficionado. In case you didn't know, there's a very nice new version of BASIC from right in your own backyard: QB64. Virtually 100 percent compatible with MS Qbasic, even gives you that same familiar editor, but it goes a lot further too. Runs fine on 32-bit or 64-bit machines, MS, Apple, or Linux, and it's a compiled version.

These picaxe devices seem to have a language simiilar to older versions of BASIC, in which variable names were restrictive.

(Now you've got me questioning how I orient the resistors on my boards. Thanks a lot!)

Thanks Aubrey!  Max is very persuasive....   Ref assembler - this is one of my questions that I will be investigating for a further blog, so you'll have to wait!  I know it does let you access the different memories (PEEK and POKE statements), but I don't know how far beyond that you can go. 

Why is the first question always one to which you have to say "I'll get back to you on that"?    I always seem to do that when I'm on  training courses.....so I guess it's karma....  :-)

David When I saw your blog on the PCB, I hoped that you had become a blogger. This confirms it. Now you have to catch as well as pitch (field as well as bowl in your case). Being too lazy to go and check it out (start of the weekend and all that) I wanted to ask if the Picaxe is in fact a standard Pic with a BASIC interpreter in firmware, much like Zilog And Intel had in year's past? Also is it possible to descend into assembler?

David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
