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. Will I be better off with just continuous loop inside thread or the timer will do? Thank you.
