python - How does PySerial work? -
To read the serial data from my Arduino, I have the following Python script: Serial ser = serial.Serial Import ("dev / ttyACM1", 9600) ser.timeout = 2 ser.readlines () On the other hand I started my Arduino with a program Which sends each voltage readings in 20 seconds. Arduino starts sending those readings from the moment that it is tilted, then after 20 seconds it closes and does not send anything. Now what I have noticed is that I can read those 20 voltage values using the first script I need. That is, I can hook up Arduino, wait for a few minutes, then read in the values. I think the data is being stored anywhere. I think it is not being stored on Arduino, but somewhere on my laptop. I have come up with a few questions which I hope the community can help me: Where to get data from PySerial (Arduino or some buffer on my laptop) Happening? How much time is there data stored in this place? Is there a way to clear this place before reading the values? ...
