[dev65] TC65 with SPI

[Fabio Nicolas Schmidt]

Daniel and Romain. Thanks for the reply.

My problem was solved when I created 3 classes, each one with its own AT
Parser. I Instantiate ATCommand and never close it. I made this classes with
static methods, and initialize them when my program starts. I believe you
can use ATCommand.release to "instantiate" ATCommand, but I´ve not tried
using it.

Hardware with GPS I´ve still worked too, with a XT65. I started working on
them to receive a help paying my university, so I did a project called
"Vehicle Tracking and Monitoring using GPS", where I did a very rudimentary
Java software, where it basically only open a Socket connection and receive
command form a remote computer. On this computer I developed a software
Using LabView. This software controlled the XT65. Very simple. Sometimes I
got some errors from java, but it worked fine.

I don't know if I can post photos, but I will try.. This photos are
historical. Two years ago I tested my XT65 using a protoboard. After testing
it I built a PCB with all necessary components, as you can see in the
photos.

Have you ever needed to program a thread to execute on a specific day?
Explaining:

I Have a .txt file on the module"s file system. I read it (its data is
separated with ";"). This txt file is like a system.ini file, where I keep
the software configuration. Into this text I have the month, day, hour and
minute that I want a thread to execute. I couldn't find how do it, does
anyone have did it before?

The second thing I am doing is Writing this TXT file using an external
software, where this external software transfers this .txt file with the
settings into the module's file system. I couldn't find on siemens manual
how transferring files over AT interface, but using a Serial Port Monitor
software I discovered that the MES (Module Exchange Suite) sends the
"AT^SQWE=3" AT command and opens an OBEX system. It sends all files using
this.

I've still studied what it sends and I can write the file on the module, but
if someone have the OBEX protocol it would be fine, because what I'm doing
is pretty what we call "gambiarrra", or "the Brazilian way for doing things"
(laughs).

Thanks.

Fábio.
