I'm using LoPy with Pysense connected to the Pc via USB.

Is there a way to read the accelerometer data sent by the Pysense and plot it with Spyder for example ?
I would like to use matplotlib library and use the data from the COM port to make a live plot.

This is the code I use :

import serial
import time
ser=serial.Serial(port='COM4',baudrate=9600)

while True:
    print("try")
    time.sleep(10)
    s=ser.read(100) #reading up to 100 bytes
    print(s)

ser.close()

And I get "access denied". When the Pysense is sending data, I can't read it because the port is already in use.
SerialException: could not open port 'COM4': PermissionError(13, 'Access denied.', None, 5)

So I guess while Atom is using the port Spyder can't access to it ? Am I right ?

How should I do that ?
Is there an easier way to print data ? I don't have SD card and I don't want to use one.

Cheers,

Close Atom, when you want to read form the serial port on the PC. You may also use a WiFi connection and sockets.
