Re: New to group

 

There are some analog monitors in the $30-50 for 7"  -- they are used in automobile video systems.  HDMI seems to require jumping up to video production (add to HD Camera) and over $200.  I'm keeping my eye out for something that's hdmi and sub $100, keeping with the spirit of the Pi. :) -- the attached link contains some discussion on using the Pi for D-STAR.

X Forwarding

Rick
 

I have tried to implement X Forwarding on the PI.  I checked the sshd_config file to make sure that X11Forwarding was set to YES and then logged in ssh -X pi@hamradiocomputer.  The hamradiocomputer is running Ubuntu and I am logged in to the PI over ssh and all is working well there.  Then I typed the name of a simple GUI based program, putty.  After a long pause I received the message: (putty:1522): Gtk-WARNING **: cannot open display

Can anyone point me down the correct path?

Re: PI on packet radio - need script help

Thanks for the MiniCom config info. I did read the menu but did not understand it. Your definition makes more sense. I will give it a try. I did get the "single word" config start up file to work thanks to some good input here on the users group. I also tried PUTTY and it also can be configured for my serial/UART IO packet TNC operation. But it does not run as fast as MiniCom. Probably because PUTTY runs through the GUI which of course eats RAM. All and all I am pleased where this all has ended up. Thanks guys, great help.

John,
You can use the text editor or you can use the configuration feature in Minicom. Just do a CTRL A then Z and you will get a big menu.  Select "o" and then set up your parameters. Then hit return and you will get another menu.   Type in the name you want to call the configured file for Minicom and hit return.  I may have missed a key stroke, but you'll get the idea.  It's really quite friendly.

I have my PI running on packet radio just fine thru an external rs232/UART PCB.

I am using MiniCom and have to type a string of variables when I start the program.

I would like to generate a script file (?) where I could issue a single keyword like "Packet" and have it start MiniCom with its variables . I have a basic understanding of IDLE and Python but I need a raw beginners (exact Syntax) to make a script file to work. I don't care if the final product that has to be used in xterm or from the GUI.

The string I am trying in to get into an executable is:



MiniCom -b 1200 -o -D /dev/ttyAMA0



I have tried to find a GUI based terminal program that allows one to enter set up data after starting but no success there. (Putty, cutecom , microcom)



Any help would be greatly appreciated

Yes, select Connection Type Serial, and then put the dev info '/dev/ttyAMA0' in the Serial Line box.

John,
You can use the text editor or you can use the configuration feature in Minicom. Just do a CTRL A then Z and you will get a big menu.  Select "o" and then set up your parameters. Then hit return and you will get another menu.   Type in the name you want to call the configured file for Minicom and hit return.  I may have missed a key stroke, but you'll get the idea.  It's really quite friendly.

Re: PI on packet radio - need script help

I run minicom on the Raspberry with the parameters I need for the PK-88 I'm using.  Just save the configuration under a unique name like "packet" and all should connect as your configuration indicates.  I'm just a newbie so you shouldn't have any trouble either.

PI ports

kc2eq
 

On the PI PCB , on the opposite side of the SD card there is an edge card connector that looks like it is in parallel to the SD card solder pins. Can one stick a different type of storage card in this slot that has the OS image on it! If so, what kind of card is it?

Premature PI shut down

Working with a friend (AC2HE) who just got ver B PI . It shuts down after about 5-6 min. Power supply is stable, still puts out 5 volts after shut down . 3.3 V reg ok also.

Anyone have this problem? My PI has been working great ever since I took it out of the box.

Re: Issues reprogramming SD cards

 

Make sure the "boot" flag is set.



I've had no issues 'burning' images' to new SD cards but reusing SD cards, even after reformating with an SDFormater,
fails to produce cards which will boot. The 'hang' in the same place. I've tried 'quick' format and overwrite erase
format. Two cards do this, both class 10. Verbatim cards and another from the same batch is working fine (although on
its first 'burn').

Re: Changing Desktop

I guess I'm not sure what the problem is.  Here is how I changed my desktop.

Grabbed a convenient .jpg file.  Brought it into my pi home. then did a sudo cp to the /etc/alternatives directory.

The used the procedure below to change the desktop background to the new jpg file.  No problem!

Thank you Dave, I'd tried that and located where the 'target' file is really located, the type, size etc. I'd place a new file of the correct type and size in the same directory and used the procedure you refer to to select it.

The problem is, it didn't change.

File permission all look good.

I'm assuming I've missing some nuance which I was hoping someone else knew.

It isn't a 'show stopper', I've got everthing else working, it would just be nice to have the school logo on the desktop.

It seems such a trival thing, every thing else has been straight forward- well other than trying to reuse some SD cards. Than is causing some grief at the moment.
