Arduino Firmata Qt-Application
are there any snippets, examples available, how to control
an Arduino from a Qt Application using "Firmata" ?
On microcontroller side is more or less clear, but i don't know
how to design the Qt Application part.
From a quick overlook at the firmata test program, it looks like you need to use QSerialPort for the communication. Then implement their protocol. One thing you could to is port firmata_test to Qt.
Yes, i will, but first i must see any advantage of using firmata instead of a custom (e.g. switch case parser) protocol.
I do not get the philosophy behind firmata yet.
You mentioned above this :
Yes, that's exactly the one
Nobody know a simple Qt example using firmata to, lets say,
switch the led (p13) on and off from a Qt application ?
The above mentioned examples are too complex to learn.
Serialport implementation not needed, maybe even pseudocode
Do you mean something like "that":http://code.google.com/p/firmatator/ ?
