I have an application where I need a processor that can send out some
very simple commands via rs-232. (TTL level fine). I need to send
that data to at least 2 components, so I need at least 2 rs-232
ports, unless I want to introduce some switching, which is not
impossible as long as there are a few available I/O lines to use to
control the switching. I also need at least 6 or 8 I/O lines. Most
importantly, the application needs to incorporate a simple, small,
touch screen display, and it must include bluetooth.
My plan was to use the XM4-BT, the ConsoleLCD-vx, and the Samsung LCD
(although it may be a bit large, but fine for initial prototypes).
Will this combination give me what I want? I believe it will give me
a touch screen display, at least 3 rs-232 ports, and a bunch of
digital I/O lines, but I am not positive from reading the material.
Also, even more importantly, I have a very special Bluetooth need. I
need to be able to have the bluetooth device on the board talk to and
from 2 headset units. But, each headset unit will be on a different
channel. In other words, they will not be talking to each other, or
carrying the same data. They will each be sending and receiving voice
to different places. Can this be done with the Bluetooth on the
XM4-BT. I suspect it can be, without any problem, since a Bluetooth
controller is supposed to be able to control and communicate with up
to 7 units, so I see no reason that the data going and coming from
the 2 headsets would have to be the same, but I am not sure. Any help
or suggestions would be useful. Of course, I could set up a system
with 2 Bluetooth units, one for each headset, but that would require
me to add an additional Bluetooth transceiver, which would be totally
separate from the one offered on the XM4-BT (and would require at
least one more rs-232 port, not to mention the possible RF problems
of having two Bluetooth transceivers located in the same physical
enclosure, although they are supposed to be interoperable.)
