7" Tontec LCD Display

[ChrissHamm]

I was looking at the 2.4 LCD display setup, but when I download the .zip file from amazon I don't get the user manual and how to configure the raspberry pi to see the display. I am very, very new to Linux, raspberry pi, and setting up hardware. Can someone help me? What are the key things I need to understand.

Hi Chriss,
Could you clarify what you are looking for? the title says 7" display (Like this one?) but the text says 2.4(inch?) (see this thread about issues with Tontec 2.4" display (so far unresolved)).

HI Doug,
I have the 7" display but the video I saw was on the 2.4 " display. I thought I had to have src files like they did in the video, but it turns out that the display found what it needed and worked when I plugged it in after getting the raspberry pi up and running. Thanks for responding.

Sincerely,

Hi Chriss,
Glad you got it working.

(I thought it should just work if you had the same one as I linked).

Ok, I have this display and I cannot get it to work.
Does any one know if I need to do more than just plug it in or am I going to have to learn Pi programing in order to use this device? Seriously. Ready to chuck it out the window.

Hi Dingus,

If you have the 7" display you would need to plug in a power supply and the HDMI lead and then it should just work.

Have you confirmed that your Pi works with a different display?
Do you have a separate HDMI source that you can use to check if the display is working?

The Pi needs to see a HDMI monitor within a few seconds of switching on or it will assume no HDMI is available and output its signal on the composite instead, - Ensure that the HDMI monitor is on before switching on the Pi to avoid this issue.

Hi! Thanks for the reply.
I got hooked up with someone that has done this before and had to do some code work to tell my pi to see the monitor and suck. I still cant get the touch screen part to work and I dont know if I need to get some code for that. When it comes to writing code or even knowing what to do with the code I am lost.
So I am using the screen with out the touch part. At least it didnt cost me a ton of cash right?

Hi Dingus,

Have you tried contacting Tontec for help with getting the touchscreen working? their amazon product page says that they are happy to help.

[dingusmcgee]

yup...waiting for a reply....

Hi Dingus,

Looking at an amazon listing for the 7" touchscreen Tontec, I can see that one of the posters linked to this blog post. he found that it didn't work with Raspbian until he re-compiled the kernel.

I have installed latest Raspbian image on a SD_Card and tried it on my Raspberry PI model B, but the touchpanel didn't show any input. After searching a lot I have decided that I have to recompile the raspbian kernel and add support for touchpanel. This sounded very new to me but it seemed to be an easy task.

you could try compiling the kernel following the instructions on his blog or using his compiled kernel (also linked on his blog).

I hope this helps.

Ok Ill look into that.
Ill have to figure out how to compile and do what this guy says to do. I ordered some books on programiing the pi and such but haven't gotten them yet.

He does have full instructions and a link to his compiled kernel if you want to use that.
