Re: Good Small Monitor Suggestions?

flask28
 

I was looking at these I found on fleabay:

http://stores.ebay.com/chinatobby/Driver-Borad-TFT-Display-/_i.html?_fsub=485977719

HDMI, 12v, in a variety of sizes and resolutions. I was thinking of putting my RPi in a Pelican case or something like that for mobile Packet use and I thought these might be a good monitor for that.

But I haven't purchased one yet.

Folks:

Has anyone discovered a small monitor, maybe 7 to 10", that has reasonably good resolution? I see several advertised on MCM and Amazon, but I am not sure if they are good enough for the job. Often the adverts don't even list the resolution in the specs.

I could buy an HDMI to VGA converter, and use a regular VGA monitor, but those adapters are quite expensive, and seem counter to the philosophy of the PI.

So far I have found either the low resolution monitors above, or acceptable resolution in much larger (20"+) TV type monitors.

Just wondering what others may be using.

Re: Good Small Monitor Suggestions?

 

Hi Dave,
What type of adapters does it need for HDMI in and USB for keyboard?
Are they readily available and decent prices?

Thanks

Not sure if it's what your looking for but you can get a "Laptop Dock for Motorola ATRIX 4G" for about $80.00 10" w/ keyboard. Needs some adapters.
I have seen many Raspberry Pi people using these (I have one - works well).

Re: X Forwarding

Yep.

I'm using XMing, the windows x-windows server, and putty with x-forwarding selected, and it works great.

Give your pi password and you should be in a shell.

At this point

*lxterminal &*

Tried that. Bought the 7" composite monitor from MCM. Poor results (resolution).
The PI looks great on HDMI. I settled for a HDMI to VGA converter. 22inch monitor
(VGA) is ok. The smallest I dare go is 10-12 inch for the sake of resolution.

You have to connect to the Pi with -X as well. Also you must make sure
your own PC is capable of running X apps (if not Linux, you must
install an X server).

I have just tested your scenario using two Ubuntu machines (PC -- ssh
with X --> PC -- ssh with X -> Pi) and ran an X11 application (midori,
I did not have putty installed on my Pi) perfectly fine.

Re: PI on packet radio - need script help

kc2eq
 

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

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.

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?

Done.

You can also do this without an editor

echo "MiniCom -b 1200 -o -D /dev/ttyAMA0" > packet

chmod +x packet

...

If you move it to something on your path you can execute it as packet from anywhere rather than ./packet from the directory where you created it.

You can find your path by

echo $PATH

Then if you see something like /usr/local/bin

cp packet /usr/local/bin

Et voila!
