Improve PBP with integrated configuration

[cncmachineguy]

Kirk, the link provided in your request for defines does not go to the datasheet. It goes to a very well written post explaining the concept behind turning off the A/D function so the multiplexed pins may be used as digital.

I for 1 am sorry you are having such a time right out of the gate. Programmers writing for the stamp only have 1 choice of processor. Pretty easy to cater to the PIC so the programmer doesn't have to learn how it works.

PBP handles a multitude of devices. Not all of them work in the same way or even use the same registers.

Excellent typo - I think you meant Stamp, but your sentence describes succinctly what needs to be improved in PBP - make it so the programmer doesn't have to learn how the PIC works! Stamp Basic automatically decides based on the programmer's code whether to make a pin digital or analog so the programmer doesn't need to know how that is done. That's what a computer language compiler is for, so the programmer programs at a more abstract level than assembler.

PBP's design is a generation too old, from the days of Peek and Poke programming. If PBP has to cover different internal code for different PICs then the programmer should only have to name the processor such as "include 18F4550.bas" or use the drop-down menu to get PBP to generate the right code for that chip. Any need to resort to ASM should be pre-empted by the redesign of PBP, as should any need to set up a configuration, especially the code to get the chip to simply work. However, the PBP redesign should be done carefully to avoid the language complexity and code bloat that came in as Microsoft moved from GBasic to Visual Basic.

My qualifications for making suggestions to improve the PBP product include several years of working with a Stanford student to specify a new higher level computer language which he built in VBasic.

That is cool.
But when you are dealing with hardware things change. The Stamp gives you an "OS" of sorts, kind of like Windows when using VB.

Other than the underlying BASIC syntax between the Stamp, PBP, VB, etc, they are all different animals. You know that.

Even when using a Stamp, a person has to understand the hardware to do "advanced" projects. But it would be nice to be able to do like they do in Star Trek, "Computer, Make My Lunch" and it be done.

Now you get it! If the PIC hardware can't help, a PBP software emulator for PICs could allow code testing seperate from burn testing. (Today I burned through 3-4 PICs and only have 3 left.)

If I were better at defining a language, I'd be on my way. Now I have a language that is only at "chatterbot" level which I'll have to rewrite in C++ to improve things to drive a robot to make lunch.

Hey Bert, tell him about the sim you use...

But think of the hardware involved

After 10+ years of PIC's the hard way (coding in ASM) with no money to buy any real tools, I got turned onto PBP. Even though I am very used to the datasheet's provided by microchip, I still had a learning curve for PBP. Do I think it should be written differently? NO, NOT AT ALL!!! As soon as you take the time to learn something about these fun little gems, you will appreacite the versatility provided by PBP.

The sim Dave is talking about is Proteus VSM. Its an awesome tool for testing code and some hardware. hardware not being its strong point. Before having this I used ICD from microchip, and microchip sim in MPLAB. All great tools. But you still need some understanding of whats going on. There are plenty here who are glad to help and very knowledgeable. They all help anyone who asks for any help. Not all know everything but all seem to know something and I have yet to see a problem un resolved or a newbie ever ridiculed. This is one of the most comfortable forums I have ever been on.

Having said that, let me please also point out this: I realize this is a wish list catagory. As such, you can wish for PBP to be anything you want it to be. but wishing for it to be something else and bashing it are 2 different things. If you want help here, try not going after what the rest of us believe in. We like PBP. are there some things that could be different? maybe. If you are so well adapt with C++ why not use one of the many C-style compiliers.

As for feeling like you should be able to use the PIC's without understanding them, thats just silly. Here is my take on this: I drive a car. Do I need to know how it works-NO. but if I want it to go faster, get better MPG, or do anything else the manufacture didn't build in, I will have to learn how it works. So the analogy is this: use the stamp, want more speed use the BS2 I think its faster. want to get under the hood because its not fast enough for you? LEARN how it works. MANY MANY MANY others before you have learned with the material and support available to you. MANY more will learn after you.

And BTW, maybe I like the datasheet because 20 some years ago we were taught in college how to read datasheets. back then you were proud to own the big yellow TI data book explaining all you never wanted to know about 7400 series devices. If you think the datasheet should read like a book, it wouldn't be a datasheet of 300 pages, it would be a trilogy of 600 page novels.

It would be nice if PBP did everything it could including setting up each chip function (such as PWM or A/D or simply flashing LEDs) when called. That change is not too big to suggest or ask for.

I started programming MPU's back when Parallax only had the BS1. Now I only use the BS2px24 and it works but too slow. I started building an Altair 8800 soon after first advertized on the cover of Popular Electronics Jan 75 and it arrived. I had no soldering errors with the original kit and programmed by front panel switches. I graduated in Computer and Information Science in 1982, less than a year after they moved the compiler class up from a senior level to a graduate level class so I missed it but got notes from someone who went on to graduate school. I do not yet know C++ but so much stuff is written in it I'll learn it. I've already invested in PBP at the recommendation of the teacher who helped me move up from the Stamp to the PIC.

I've been spoken of by a guy who learned to read late in life as someone who could take a paper, convert it into a paragraph and not lose anything. So I know the data ream can be condensed.

Most importantly, I've become what is likely the world's expert on the difference between traditional churches and the true church which came down from heaven in Jesus' blood. I hope to start it soon. But most adults seem too old to change.
