Reading from a serial port in Python

read_serial.py

import serial


# this port address is for the serial tx/rx pins on the GPIO header
SERIAL_PORT = '/dev/ttyAMA0'
# be sure to set this to the same rate used on the Arduino
SERIAL_RATE = 9600


def main():
    ser = serial.Serial(SERIAL_PORT, SERIAL_RATE)
    while True:
        # using ser.readline() assumes each line contains a single reading
        # sent using Serial.println() on the Arduino
        reading = ser.readline().decode('utf-8')
        # reading is a string...do whatever you want from here
        print(reading)


if __name__ == "__main__":
    main()

Helpful!

Thanks!

Thanks a lot!

Did the job! thanks!

Nice

Thank you so much.

boa

Thank You so much

It is a nice code. I have added few more lines to let the users input the desired device location and baud rate. Feel free to update the same from my fork. happy coding!

Thank you

Thank you!

Thank you very much.

I am trying to read data from Emlid RS2+ via RS232 port baudrate = 115200. My code just gets stuck in "ser.readlines()" line.
I am using Jetson Orin. Any suggestions?

import serial
Serialport = '/dev/ttyACM0'
#Serialport = '/dev/serial/by-id/usb-Emlid_ReachRS2_8243D27C83B34ACE-if02'
ser_rate = 115200
def main():
ser = serial.Serial(Serialport,ser_rate)
while True:
reading = ser.readlines().decode('utf-8')
print(reading)

if name == "main":
main()

I can also provide further details on it if needed.
