Debugging Question

Blake Koch

Does the "PST Debug LITE" Object still exist? If so where can I find it?

Thanks Blake

Thank you.

Blake Koch

Let me start with I'm working out of the book "Programming and Customizing the Multicore Propeller"

I just downloaded the "PST Debug Lite" Object

I'm working on page 91,92 of this book

I had a error message after compiling this code that required me to Change the books code.

From
debug.Style(debug#COMMA_DELIMITED)
debug.Start(115200)

To

debug.Start(debug#(COMMAS)

To clear the error code. After doing so the example on page 87 Step1 and step2 worked perfect with just the debug.start(debug#COMMAS) name change.

However in step 3 Page 91,92

I have entered the text exactly as I see it written on page 91,92 when I try to run it nothing works right. the number on serial display are all over the place and the numbers do not add up.

(SEE CODE IN LOWER MESSAGE)

and what I get out the other end is just numbers all over the place. nothing lines up.

Can anyone help me with what am I doing wrong?


Thanks Blake

Since spin uses indentation to control blocks of code (repeats) you should post your code using the code feature of the forum.

If you look at the list of small icons above the editing area, one of them is a C. If you click on that you will get [ code][ /code] (without the space after the [ and before the C or /.

I place the cursor between the ] and the [ and hit enter a couple of times. Then you can just cut and paste your code from the proptool (or whatever IDE you use) between them. That way the we will be able to see the indentation and be able to help better.

Ok that's cool. Thanks for the help.

Blake,
I have attached a copy of the version of "PST debug Lite.spin" that is used in the book.
Note that you have to go back to using:

  debug.Style(debug#COMMA_DELIMITED)
  debug.Start(115200)

When I run the program below with this version I get a printout that looks like the one on page 92.

Try cutting and pasting the code in the yellow box into the prop tool.

You will have to download the attached spin file. Go to where you currently have your version of PST debug lite.spin and rename that file (just add an x after lite). Then save the attached version of PST debug lite.spin to that folder.

Hope this helps

My initial attempts to use PST Lite weren't successful.

I switched to Parallax Serial Terminal.spin and used a less elegant formatting technique to get the data to appear the way I wanted it.

Sorry for not helping with the PST Lite but hopefully the example below will be useful.

You had an indentation problem in the "TimerMS" method.

The above code outputs the following text.

 minutes = 0, seconds = 9, milliseconds = 354

Blake Koch

Thanks you for the right copy of "PST debug Lite" that made all the difference.

And thanks for the indent info I saw that after I posted it.

Is the PST debug only for windows? I don't find a mac version tho.

Now that I have the program working, I have a question about the code.

  repeat 
    longmove(@minutes, @m, 3)                                                                           'Copy TimerMS vars
    debug.ListHome                                                                                      'Display values
    debug.Vars(@m, String("| minutes, seconds, milliseconds"))                                          '
    debug.break

The go method initializes three local variables (MINUTES, SECONDS, MILLISECONDS

Q1) Is longmove and debugV.Vars the only place these variables used? I do not see them come up anywhere else in either Object.

Q2) How does longmove migrate all three variables (m,s,ms) into all three new variables (minutes, seconds, milliseconds) when it Specifies one variable ( @m to copy to @minutes, 3 long of @m)?

Thanks again.

JDat

Technically: If you are debugging spin, than clever use of serial(name as you want) .dec(), .hex(), .bin(), str(), and .tx() is enough.

After load cell programming (1000 samples per second 12 bit data) I also like Serial plotter from Arduino IDE (compatible with propeller after some tricks) for data visualisation and Realterm to validate low level binary data to meet custom protocol specifications.

ASM for advanced guys? That another story. I'd prefer PASD. It works fine with latest propeller tool on windows 7.

Since the three variables are consecutive, they all three get moved together. The variables in both locations need to be consecutive in order to use longmove this way.

I assume the method "Vars" assumes the variables are consecutive.

Blake Koch

Thanks for description of how longmove moves consecutive variables. I kind of thought that, but wanted to be sure.

Blake

twm47099

The @ in front of the m means the address of m.
So it is moving 3 longs that start at @m. When declaring vars, spin locates them consecutively in the order declared.

In a VAR section, the order is maintained, but only in groups of the same size. The Spin compiler will group all long variables at the beginning of the VAR section, followed by all the word variables, and then followed by all the byte variables. In a DAT section, the variables are maintained in the order that they are declared, independent of the size.

Blake Koch

Thanks this all help my knowledge of how to move these variable around.
