I just tested the program on the device and on x86. On x86 it produced correct

So it looks like I will have to switch the endianess when running on the

This is portable and clear to any future maintainer. The efficiency
loss is negligible.

Hi, ALL,
Apologies for possibly screwing up the threadding. I accidentally
killed the messages in my INBOX.
My (hopefully last) question here in this thread is: g_io_add_watch()
should take a callback (i.e. static function) or just a regular
function?
Thank you.

Are you writing in C or C++? I assume you're using the straight Gtk for
C as the function

Is it possible to use m_data with GIOChannel?

of course.
but you'd better hope that the compiler packs that data structure in
the same way the device is sending it. you'd be far better off not
using a struct for this, but just reading (in your case) 10

one thread. this has the same problem that anything using a (G)UI

Hi, ALL,
I read that the timer event processing is differ between x86 and ARM.
On x86 it fires at 1/1000 interval, on ARM it fires at 10/1000
interval.
If I use g_timeout_add_seconds( 1, ...) am I guaranteed that the timer
events will fire with 1 sec interval independently of the arch?
Thank

Hi, Paul,
My task is to read the external device thru the serial port with the 1
sec interval.
And then update the GUI with the new data.
At least the documentation of this device says that it will write with 1 sec.
I am testing on x86, then cross-compiling for ARM and run the program on ARM.
