'DEBUG' command alternative in SX/B???

Ductapemaster

I just got my SX lite kit today and I started learning some SX/B, but I noticed that there is no 'DEBUG' command anymore. Is there any way to display data on the computer instead of a display (like SEROUT to the computer)? I would prefer not to have to buy an LCD now that I already bought everything.

Any help is appreciated.

Dan,

You can use SEROUT, just remember that everything is sent byte-by-byte. Take care.

Dan there isn't·a Debug function·like the BS2 on the SX. Debug is possible with the BS2 series, because it·has an eeprom that controls the pic or sx chip on a BS2 and thats also the reason the BS2 is so much slower than the SX.

We use the SX-Key to to real-time debuging and SX-Sim to measure the time a routine takes and how many cycles it consumes. Unfortunatly the sx-key only allows 1 "BREAK"·statement to be used at a time, so we get around it by calling a subroutine that contains the "BREAK" statement. You declare it like this:

BREAK_NOW········· Sub···· 0



When you call the Subroutine, just add the line BREAK_NOW, without a GOSUB.



(then the sub routine is)

BREAK_NOW:
BREAK
RETURN

Then use as many WATCH statements you need·to follow any of the variables like this:

(I add them before the subroutine declerations)

WATCH Var, #of Bits, UDEC· (unsigned decimal) look under help

Also, there is more code examples within the SX-Key directory, inside the Examples folder and then under SXB.

I wasted a lot of time trying to create some sort of BS2 like Debug. Just learn how to use the SX-Key Debug feature and SX-Sim and you will be able to do more than the BS2 Debug can.

Keep in mind that WATCH is now an SX/B keyword as well as a compiler directive, so if you want the flexibility to specify the bits and format, you need to precede that command with \ to embed it as an assembly command; when using WATCH in SX/B, the default format is decimal.

For example, if you have a word variable and you want to see the state of the bits you would do this in SX/B:

\ WATCH myVar, 16, ubin

If decimal mode is okay, you can simplify to:

WATCH myVar

Thanks guys, thats just what I wanted. I am building a thermometer with a DS1620 and I like to test my programming with the computer before I hook it up to displays. It's nice not to have to write extra code to drive them.

Thanks again,

Although a very minor point, I believe that

\ WATCH myVar, 16, ubin

and

WATCH myVar, 16, ubin

are now equivalent statements.

Well, kick me in the teeth, they certainly are. Thanks for pointing that out, Sparks.
