Debug Display options (Was: Sending Data from QBasic to BS2sx)
Archiver
Posts: 46,084
I had a similar problem trying to develop a prototype for a company I was
working for. ALT-TABing does work, but it's cumbersome and confusing. I
got around this by purchasing a serial LCD to use for all my "debug"
output. It comes in really handy when you are trying to arbitrate serial
port activity.
Plus, to see the result, you just look over at the device you're working
on which somehow seems more "natural" to me. I'm used to looking over for
status leds or servo positions etc. [noparse]:)[/noparse]
Scott Edwards electronics was the one I bought which I think you can get
through the parallax web site. There are now some other vendors that
offer the same type thing with different size displays. I opted for the
back-lit display and it really is easier to read than the non-lit (I got
one of those for a later project and missed the back lighting dearly!).
Check Nuts and Volts mag for ads (http://www.nutsvolts.com) or parallax
(http://www.parallax.com) or even Scott Edwards (http://www.seetron.com)

Comments
this when I started up my qbasic program after the stamp programmer
was open, I got an error saying 'two devices are trying to use the
same port'. So I hooked up a led and told the stamp to light it up
when it got the string of text I was sending from the laptop. The LED
went off, so I guess it was working all along, the debugs just
weren't showing up; probably conflict between qbasic and the stamp
programmer which may occur differently on different computers, mine
is pretty old, and I was running everything from windows 95 (although
the DOS mode bs programmer always has worked from within win95).
Thanks for the help guys.
