Sout pin for serial transmission

DrumAdrian

Hi,

·I am using a Javelin stamp to do quite a few things for a·project, and I am running short of pins.· I want to know if you can use the Sout pin on the Javelin to send serial data when executing a program.· It would be great if I could use the pin to send data after the stamp has been programmed.· I know the BS2 will allow this· but what about the Javelin.· · Thanks in advance.·

Not really. The Javelin uses the 'Debug' serial port interactively to support single-step debugging. As such, there's lots of stuff coming out that serial port, along with the message you really want to send. I suppose you could try to 'filter' the junk and keep just your own stuff.

It's unfortunate there's not an option to turn this off, so you COULD use the built-in port as a generic serial port. This is why the Javelin development board has TWO DB-9 connectors, and a MAX232 chip, to support using any of the other I/O pins as a true UART.

Here you find the sout pin protocol

If you can filter out the meta bytes you can
use System.out

Oh, Peter, well done! Thanks for the protocol, now we CAN filter the junk.

Could someone email me that doc? Apparently you need to have a Yahoo account to get it... scottm@net1plus.com

I attached that here for you.

You can join the JavelinCode group for free.

There are lots of Javelin·classes to download.

I adapted the JavelinDirect source code

to filter the Javelin Sout pin data.

The attached program displays the Sout pin data

(as text data) and also catches that to a file.

The source is here:

Solved a few problems I ran across with some Javelin programs.

This new release opens a com port without interfering with a running

Javelin, so a 3-wire cable (TX, RX and GND) will suffice.

(Javelin debug port requires·RX line to transmit data)

So you can hook up a laptop to check a running Javelin

without disturbing it.

Have updated the JideDebug utility with the ability to send online text or a text file

to the Javelin using its Jide port (and thus renamed it to JideTerm).

This allows for .ini files or whatever to be send.

I have written a JideTerm class that 'collects' a message via the Jide port.

How this message is further processed is not specified.

You'll find the sources and JideTerm test files here

http://groups.yahoo.com/group/JavelinCode/files/JideTerm/

and here is the JideTerm class

http://groups.yahoo.com/group/JavelinCode/files/Javelin%20Stamp%20IDE/lib/stamp/core/



Being able to send a file allows for easy configuration of startup values without reprogramming

the Javelin.

Hi,

I have uploaded a windows version of JideTerm here

http://groups.yahoo.com/group/JavelinCode/files/JideTerm/

Also attached it.

This has a fixed screen size of 80 columns with autowrap.

Echoed characters are filtered out. Characters are not send to

the Javelin until clicking send. Output to screen (and optionally logfile)

may be paused, but while paused, the program keeps responding

to Javelin data requests, so the Javelin program continues to run

and is not blocked.
