Hi,

The code for reading the values given by the sensor was written in C, before i
started on gtk.
It just reads a value from a digital oscilloscope, through the PC serial port,
and stores it in a float variable.
Anyway, how do i set the function priority?
Perhaps i should use GtkPlot, as suggested by Adrian Feiguin. Thanks,
Nilton
