reading and parsing strings

1. Hi,

    

   I am getting from serial port 2 , GPS string
   continously.  I am willing to catch only the strings which starts
   ‘$TGPS,’ and finish ‘*’char by separator ‘,’, end put each field into
   variable.

    

   I need example code 

    

   Thanks

   1. Python has a string split function which makes an easy job to split first by  NMEA terminator <CR><LF> then by , .
      

      1. Thank you for reply,

          

         Its my first script using Python in my life. I used Java G24 before and assembly. I dont have so much examples for split function

          

         I can use the string end charactrs   , the gps module that i am using its customized string. 

          

         Thanks

         1. Hello!

            I do this things as shown below:

            #Module: GE864-GPS, Internal using of GPS

            import GPS

            x = GPS.getActualPosition() 

            #Get GPS data from internal Python module

            GPS_list = x.split(‘,’)

            #Split GPS data into list (throw the separators: ‘,’ )

            #Now, for example, parse some NMEA elements into variables:

            GPS_Fix = str(GPS_list[5])                 #VALUES: 0(invalid),2(2D),3(3D)

            GPS_Time = GPS_list[0][0:6]            #FORMAT: hhmmss.sss

            GPS_Spkm = str(GPS_list[7])           #VALUES: from  x.x   to xxx.x 

             

            etc… 

            Good Luck to You!
