I need some help writing a TCP server (like the one below) in "c" rather than python. REASON: I need to write data to my Gertboard through the Raspberry Pi's UART RX/TX GPIO header. I can't find any examples of how to do the Raspberry Pi GPIO with wiringpi.
Below is my current Python Script for writing data to an Arduino ATMEGA connected through the USB port:
from time import sleep
import sys
import socket
while True:
s = socket.socket() # Create a socket object
host = '192.168.12.24' # Get local machine name
port = 9999 # Reserve a port for your service.
import serial
DEVICE = '/dev/ttyACM0' # the arduino serial interface (use dmesg when connecting)
##DEVICE = 'COM12'
BAUD = 9600
ser = serial.Serial(DEVICE, BAUD)
try:
print "Server started on", str(host) + ":" + str(port)
print 'Waiting for clients...'
s.bind((host, port)) # Bind to the port
s.listen(5) # Now wait for client connection.
c, addr = s.accept() # Establish connection with client.
print 'Got connection from', addr
while True:
msg = c.recv(3) # get 3 bytes from the TCP connection
ser.write(msg) # write the 3 bytes to the serial interface
#print msg
if msg == "":
c.shutdown(socket.SHUT_RDWR)
c.close()
print "Lost connection with"+ str(addr) +"! Restarting server..."
sleep(2)
break
except KeyboardInterrupt:
print "[ALERT] Closing shell... [ALERT]"
c.shutdown(socket.SHUT_RDWR)
c.close()
ser.close()
sys.exit("Application forcibly halted!")
Is there any way someone can please make me a c version and then incorperate the Gertboard's ATMEGA device?
Thanks in advance.
