BST - Debugging with the serial window?

Hi

I'm running BST on mac and would like to send values of certain variables back to the BST serial terminal.

If I hadn't broken my EEE PC last night I'd be doing it using the Prop Tool and Parallax Serial Terminal.

Is it much the same using BST?

TIA

Adri

    BST is even better..
    it has a terminal included, and it auto switches off and on when you upload code to the propeller.
    Moreover you can save as txt the terminal contents.

    Thanks. How for example would I send the value of variable 'x' to the BST terminal?

    Sorry for so many questions but it's been a good while since I propped.

    TIA

    Any code working with prop tool and the serial terminal works out of the box also with BST. So 90% of the obex demo code will have samples available.

    I like the "parallax serial terminal" object.

    in you code:
    Under "object" include 
    dbg : "parallax serial terminal"

    in your main object start the serial cog, setting the speed
    dbg.start(57600)

    the send data to the teminal:
    Strings, numbers or chars: 
    dbg.str(string("variable value: "))
dbg.dec(value) 'converts decimal value to string
dbg.char(13) ' new line

    Can't get it to work.

    I downloaded the "Parallax Serial Terminal" from obex

    Messing with the education kit code apart from sitching a LED I think this should output "variable value: " to the terminal but it doesn't.

    OBJ
    dbg : "parallax serial terminal"

    PUB LedOnOff

    dbg.start(57600)
    dbg.str(string("variable value: "))

    dira[16] := 1

    repeat
    outa[16] := 1
    waitcnt(clkfreq/4 + cnt)
    outa[16] := 0
    waitcnt(clkfreq/4*3 + cnt)

    Works for me. Make sure that
    1. you set _clkmode/_xinfreq as 57600 baud doesn't work with RCFAST
    2. the terminal is using the proper port/baud rate
    3. the terminal is actually connected (communicate.connect)

    Hi!

    I find the bst terminal window very iseful for debugging programs.
    However, I am still unable to send control characters, e.g. ^T, ^V, etc.
    Sorry for disturbing you again, do you have this feature in your add-on list for bst?

    Thanks++
