In a iPython notebook, I have a while loop that listens to a Serial port and print the received data in real time.
What I want to achieve to only show the latest received data (i.e only one line showing the most recent data. no scrolling in the cell output area)
What I need(i think) is to clear the old cell output when I receives new data, and then prints the new data. I am wondering how can I clear old data programmatically ?
