Hi,
Found the problem, on the latest version of wheezy that i have (Feb 2013) it was necessary to set up a small script in /etc/apt/apt.conf.d/01proxy with the proxy info, once that was done all went fine.

Cheers.

Hi, Is is possible for the pi to do "software serial", i know it can do hardware serial via the dedicated Uart but can it also do software serial in the same way that a microprocessor such as a PIC or AVR can do both hardware and software serial, the software serial being able to use any g...

Hi SirLagz, Thanks for the reply. Not behind a firewall (i think - i'll check that) but i do have to use a proxy (have to setup an apt.conf file in /etc/apt with a couple of entries in it and add an entry to /home/pi/.bashrc) but this is set up exactly the same as on my first Pi (256 MB one) and thi...

Hi,
And thanks for the reply. I actually get the error after trying to do an update "sudo apt-get update".

Any ideas?

Cheers.

Hi, I seem to be having trouble getting apt-get to work. I get the following error: Could not connect to mirrordirector.raspbian.org:80 (89.16.177.202). - connect (110: Connection timed out). The internet itself seems OK for example searching with midori works fine. There have been some posts that s...

Hi, and thanks for the reply - was very helpful so i think i am very close now - this is what i have done so far: [Desktop Entry] Name=piShutdown Comment=Start a script to shutdown pi when without monitor Path=/home/pi/Documents/Programming/Python/pysource Exec=/home/pi/Documents/Programming/Python/...

Hi, And thanks for the reply. The OS is wheezy raspian and the desktop is LXDE. I did find some further information in this link (http://pclosmag.com/html/Issues/201009/page10.html) that was quite helpful. This essentially involves setting the desktop to execute a shell script in the /usr/bin direct...

Hi, I have a python file that i need to auto start once the desktop has appeared. However i am running the pi headless and a user (who will not have access to a laptop running vnc) will simply turn on the pi and after booting the python file should execute. The python file creates a GUI and starts a...

Hi, We have a rasp-pi that is running headlessly and when we want to check whats going on we connect to it with a laptop via VNC. However there are occasions when we want to be able to shut it down when we don't have a laptop present and therefore cant shut it down properly. Is it possible to shut i...

Hi, Some more information; I have just used cutecom to see what is actually coming in the uart rx line and there is a stream of characters that appears every 5s (should be just a few characters indicating the voltage). The string appears as approximately 30 characters in blocks of 4 or 5 separated b...

katesfb

Hi, I think the problem was the way i was interacting with the USB ports via python ie opening and closing the port every time i wanted to know what the voltage was (every 5s) i have changed this back to just opening the ports right at the start and leaving them open. Everything seems to working fin...

Hi, I have an RPi used as a remote logging application that makes use of three USB inputs via a USB to multi serial cable. The first inputs system voltage serial data, another inputs RFID tag serial data, and the last is connected to a modem for txting purposes. These are all brought together in a p...

Hi Techpaul, I have looked at a few python examples of using smbus with temperature sensors but none seem to show any initialising - so how would i do that? I made use of the i2cget command but it always gives the same value (0x80ff) no matter what temperature the sensor is at (is this becos i haven...

Hi, I have a DS1624 i2c temperature sensor where temperature is read as a 13 bit value (2 byte transfer). I have set up the i2c system which is working fine and have a written a python program to get temperature data from the DS1624 (see below) and this works but is not giving me the correct output....

Hi, I have a RPi running headlessly via VNC and direct cable connection to a laptop and have been testing the RPi with a few logging applications logging serial data coming in through a usb to serial converter and everything runs really well except for 1 small issue in that the RPi seems to go into ...

katesfb

HI, And thanks for the replies. I am still having issues getting this direct Ethernet cable connection to work. This is what i have done so far: Setup static IP address in /etc/network/interfaces in RPi; auto lo iface lo inet loopback iface eth0 inet static address 192.168.250.2 netmask 255.255.255....

Hi,
And thanks for the replies. Since i am connecting directly from the pi to the laptop what do i put for the gateway in /etc/network/interfaces, normally it would be whatever the router is but in this case there is no router or network.

Cheers.

Hi, Have had the RPi for a couple of weeks now and all is going well. Have written a python logging application (with GUI) that takes serial input from a sensor via a USB serial cable and writes collected data to an external USB flash drive. What we are also hopping to is to setup the pi in remote a...

Hi, I am having a few issues installing the python module to access the GPIO pins (RPi.GPIO-0.3.1a). During install i get the following error; URLlib2.URLerror: <urlopen error [error -2] name or service not known> The operating system is wheezy raspian and it is the B model Pi. All other modules hav...
