rs232 to ethernet , nmea router orange pi zero

afric

buy MAX3232 RS232 Serial Port To TTL and i Connected to uart 2- ttyS2 (pin4-5V,pin6-GND,pin11-UART2 RX,pin13-UART2 TX)

I use Armbian_5.35_Orangepizero_Debian_jessie_default_3.4.113

install  python

1. sudo apt-get install python-serial python3-serial
   

Copy code

write the script

1. sudo nano read_serial.py

Copy code

1. #!/usr/bin/env python
   
2. import time
   
3. import serial
   
4. 
   
5. ser = serial.Serial(
   
6. port='/dev/ttyS2',
   
7. baudrate = 38400,
   
8. parity=serial.PARITY_NONE,
   
9. stopbits=serial.STOPBITS_ONE,
   
10. bytesize=serial.EIGHTBITS,
    
11. timeout=1
    
12. )
    
13. counter=0
    
14. 
    
15. 
    
16. while 1:
    
17. x=ser.readline()
    
18. print x

Copy code

and i run

1. sudo python read_serial.py

Copy code

to see if ti works
after that i write onether script (i find it ready)

1. sudo nano serial_to_udp.py

Copy code

1. # Python script for serial to UDP communication
   
2. # Alex Olwal, 2012 03 24

19.         print "Example: " + sys.argv[0] + " COM20 127.0.0.1 5000"
    
20.         quit()
    
21. 
    
22. serial_port = sys.argv[1]
    
23. 
    
24. if ( len(sys.argv) >= 3 ):
    
25.         udp_ip = sys.argv[2]

38. 
    
39. print "Reading from serial port: " + serial_port
    
40. print "Sending to " + udp_ip + ":" + udp_port
    
41. 
    
42. udp_port = int(udp_port)
    
43. 
    
44. s = serial.Serial( serial_port, baud_rate, timeout=1 )
    
45. 
    
46. while (1):
    
47.         line = s.readline()
    
48. 
    
49.         if (line != ''):
    
50.                         if (printing):
    
51.                                 print line[:-1]
    
52.             
    
53.                         send( line, udp_ip, udp_port )
    
54. 
    
55.         else:
    
56.             if (printing):
    
57.                 print "."
    
58. 
    
59. s.close()

Copy code

now if you run

1. sudo python serial_to_udp.py

Copy code

you will take

1. Serial-to-UDP utility | Alex Olwal, 2012, www.olwal.com
   
2. Syntax: serial_to_udp.py serial_port udp_ip(= 127.0.0.1) udp_port(= 5000)
   
3. Example: serial_to_udp.py COM20 127.0.0.1 5000

Copy code

so  run

1. python serial_to_udp.py  /dev/ttyS2 192.168.1.100 13000 &

Copy code

and take serial data from ttyS2 and  sent it to pc at port 13000

there are 2 ways to auto start on boot
the fisrt is direct config rc.local but put inside 1minute wait to find the ethernet

1. sudo nano /etc/rc.local

Copy code

1. sleep 1m
   
2. python /root/serial_to_udp.py  /dev/ttyS2 192.168.1.100 13000 &

Copy code

before exit0

and the other to create a script

1. sudo nano /etc/init.d/serial_to_udp.sh

Copy code

1. #!/bin/sh
   
2. python  /root/serial_to_udp.py  /dev/ttyS2 192.168.1.100 13000 &

Copy code

i make it  executable with

1. sudo chmod +x /etc/init.d/serial_to_udp.sh

Copy code

and after that run

1. sudo update-rc.d serial_to_udp.sh defaults

Copy code

and after that modified the  rc.local

1. sudo nano /etc/rc.local

Copy code

write

1. /etc/init.d/serial_to_udp.sh
   
2. sh '/etc/init.d/serial_to_udp.sh'

Copy code

before exit0

1. sudo reboot

Copy code

and it worksssssssssss
