Question

I have some position data continually coming in and I am currently printing it to the serial.

Say I have the string \"5\" and want to print that to a text file, \"my

Answer 1

You can create a python script to read the serial port and write the results into a text file:

##############
## Script listens to serial port and writes contents into a file
##############
## requires pySerial to be installed 
import serial  # sudo pip install pyserial should work

serial_port = '/dev/ttyACM0';
baud_rate = 9600; #In arduino, Serial.begin(baud_rate)
write_to_file_path = "output.txt";

output_file = open(write_to_file_path, "w+");
ser = serial.Serial(serial_port, baud_rate)
while True:
    line = ser.readline();
    line = line.decode("utf-8") #ser.readline returns a binary, convert to string
    print(line);
    output_file.write(line);
