Hi all.
Sorry if this is a pain, but basically I want to develop an application
on a Tomtom, and it needs the following features (I'll explain more in a
second):
- Recieve and send to serial port
- Can program a destination into the Tomtom software and then bring it up
- Put a button in the Tomtom software to return back to my program
- Carry on running in the background whilst the Tomtom software is running.
- Whilst my program is running in the background, let it be able to come
up and temporarily suspend the Tomtom software, displaying messages to
the user.
Basically I want to interface the Tomtom into a radio, which needs
constant serial data running. I want then to be able to send GPS data to
the radio (in reply to a GPS request), let the user send pre-defined
messages to the radio, and when the radio sends text messages to the
Tomtom, bring the messages up on the screen.
I could possibly make it simpler by having a PIC in the middle, taking
over much of the work of the Tomtom, but to make a neat solution, I'd
rather be able to run my program continuously in the background, serving
the GPS requests whilst a map is displayed, and if a text message comes
in, bring it up and stop the Tomtom software.
Any pointers as to how to achieve this would be appreciated, and is X11
Basic capable of this?
I'm very familiar with BASIC, hence my desire to use this. If I have to
make a hybrid system (such as the serial data being a shell program
always running in the background and BASIC just being used for the user
interface) I'm happy to, but I'd like to try and make it all X11 Basic
based.
I notice there's little or no support for the X11 Basic on a Tomtom -
has anyone thought of setting up a forum?
Thanks all. Sorry to be a pain!
Sam
