All right, here is a very basic framework to illustrate the idea. It doesn't use anything fancy, and assumes there are no errors. In fact, error checking is what makes your software great, so that it either does the Right Thing in case of an error, or at least doesn't crash. #!/usr/bin/env python i...

I think your 'with' statement syntax is not correct, and the whole thing is too terse for you to understand. I don't think you should use gpsd yet, until you have something working. I also wouldn't worry about the order in which the serial ports are created until then (but it's worth knowing it's a...

I have an Adafruit ultimate GPS connected to the serial UART. I use the gpsd package to collect the data, which allows multiple programs to share the data. I believe it suggests the GPS tools package, which allows you to check your GPS is working. Viewing the raw data will show you have the baud ra...

this has improved the issue i used the following code [code]from __future__ import print_function import serial, io addr0 = '/dev/ttyUSB0' addr1 = '/dev/ttyUSB1' baud0 = 9600 baud1 = 115200 GPS = serial.Serial(addr0,baud0) ECHO = serial.Serial(addr1,baud1) fname = 'RaspSurvey-Output.txt' fmode = 'a'...

hi there, latest attempt (code below) from __future__ import print_function import serial, io addr0 = '/dev/ttyUSB0' addr1 = '/dev/ttyUSB1' baud0 = 9600 baud1 = 115200 fname = 'RaspSurvey-Output.txt' fmode = 'a' with serial.Serial(addr0,baud0,addr1,baud1) as pt, open(fname,fmode) as outf: spb = io.T...

thanks for the reply!!

the echo sounder and gps will be connected to the Pi at the same time using usb-RS232 adapters. echo sounder is running at 1 Hz and with a baud of 115200, where as the GPS has a baud of 9600

Hi there!! This is my first time on a forum so bare with me. I am putting together a project using a raspberry pi and python to collect ASCII data from a GPS and echo sounder, to collect geolocated depths. Now i have hit a serious brick wall, i have managed to write the following script which (alter...
