gpib and/or rs232 communication indicator

[pacp]

Hi,

I'm using IEEE 488 and RS232 communications throughout long sequences and everything is running just fine. What I would like to add is a couple of small indicators showing that the interfaces are actually working and/or data is being written/read (e.g blinking LEDs), any ideas???

Thanks!

Add a state in your state machine which toggles an indicator after every n bytes are written or read. The value of n should be selected according to the data rate so that the indicator switches state at 1-2 Hz. Go to this state between after each read or write to update the byte counter.
