I did capture the output of the terminal printout for a better check.
There are about 200 changes of the cnt obtained by "manually" turning the encoder knob on my control panel. Probably sometims cw and ccw.
I noted very few spikes : I am not shure if they are due to the time required for the serial port output or to the encoder software.
Any improvement to the program is very much appreciated.
I am really searching for a good solution.
Thanks
regards,
Ambrogio
