Mixing
Both Threads Doesn't Work simultaneously Python3 , Raspberry PI
0
Here's My code I want to start both Thread together But it isn't starting.First Thread helps me in posting my data taken from sensor to ".csv" file and the second thread takes data from that file and plots a graph by using matplotlib.SO they should run simultaneously to give a proper live graph output. Please Help.
