串口通信:
http://pypi.python.org/pypi/pyserial
应用如下(程序有点问题，每次关闭串口再打开会出现乱码现象)
[python]
import serial
from time import sleep
ser = serial.Serial(‘/dev/ttyUSB0’, 2400, timeout=1)
def recv(serial):
data, quit = None, False
while 1:
data =serial.read(1)
if data == ”:
continue
sleep(0.02) # data is this interval will be merged
while 1:
n = serial.inWaiting()
if n > 0:
data = "%s%s" % (data,serial.read(n))
else:
quit = True
break
if quit:
break
return data
while 1:
data =recv(ser)
if data== ‘c’ :
ser.close()
break
ser.write(data)
[/python]
Python连接mysql

我没有按照这种方法，因为没安装成功，我用的debian系统，采取包的安装方法
apt-get install python-mysqldb
