Bob-ii

Archiver

Hello, I have a BSII and a BOB-II from Decade Engineering, I really
haven't done anything with my stamp other than play with leds so far.
Anyway I was trying to get the BOBII to display and can't get
anything at all I do get a blue screen so I am thinking that it is
wired ok. In my decade book that came with the BOB it says that the
stamp can be wired directly with one wire if the stamp is programmed
for inverted data output, well I think thats maybe where my prob is.
If someone that has messed with these could just send me a simple
line that I could send to my stamp that should display if wired
correctly that I can look at to see what I am doing wrong or missing,
I would really be greatful.

Heath:

The BOB II can be connected directly to a BSII I/O pin, no inversion is
necessary (see BOBII manual, page 1 "Data Path"). The inverter is required
for connection to a PC port or other "conventional" RS232 serial device.
If you see the blue screen, you're getting video out of the BOB II OK. Your
problem is probably programming and/or baud rate. The default baud rate for
the BOB II is 9600bps.
Here's a simple example of code from one of my applications:

VIDX CON 84 ' Set serial mode to: non-inverted, 9600bps, 8 data, no
parity.
X=1 ' Set value of X to 1.
SEROUT 1,VIDX,[noparse][[/noparse]"{A"] ' Initialize and clear the video display, BSII I/O
pin 1 is used.
SEROUT 1,VIDX,[noparse][[/noparse]"{C0000","OUT: ","{C0500",DEC X," "] 'Display "OUT" label
and value of "X" in specified screen locations.
END

Good luck.

We have a sample application on our downloads page for the BS2
and the BOB-II:

http://www.hvwtech.com/downloads.htm

You can cut and paste patrs of that to get your setup working. It's
probably something small; the BOB-II is really easy to use.

Happy Holidays,

Heath,
Try this simple program to display from BS2 to BOB2. Let me know if you
have any problems.
