My display setup achievement :)

Tue May 29, 2012 7:29 pm

From Hong Kong to Estonia:
Image
3.5" TFT LCD (320x240) and TouchScreen USB controller (Touchscreen panel itself has'nt arrived yet)

Next day, after getting correct RCA cable and 12V adapter and connecting with RPI:
Image

Costs (Ebay) (All items brand new):
3.5" 4-wire touch panel 4.99GBP
3.5" TFT LCD 14.52GBP
Touchscreen controller 11.60GBP

So pretty cheap setup. I definately recommend getting some cheap composite display for home projects (you can find lots of those on ebay). You won't get the best video quality over a composite cable, but hey... it's 14.52£ :)
4.3" and larger ones are sometimes actually even cheaper and easier to find than 3.5.

Will update this thread when touchscreen arrives and how I will manage to get it working (drivers etc). Hopefully someone will get a nice overview of prices and won't rush to buy 150€ displays :)

I've managed to get find a nice LCD screen that is 10.2" and an HDMI board for it (HDMI IN! :) ) and I have
Managed to get a deal with a free power cable, but... It's an expensive setup, $200..... Yup...
And another problem, the screen uses a separate
Power supply so... If I decide to make a laptop with this I would be able to power the pi with a battery, but ... You would need to plug in power for the screen... What do you think I should do?...

Hi alanrpi.

I bought some time ago one 7'' touchscreen that have VGA and A/V inputs. I connected through A/V input, but the image on the screen is awful.
I think that I should lower the resolution, and make it 4:3, not wide (is this default value?)

Can you share the settings used with your screen?

Thanks.

Touch panel finally arrived. 6 hours of hardcore work: getting the touchscreen to work was easy (needed kernel recompiling and enabling touchscreen modules), but extremely hard was getting it calibrated (most of calibration software did not work with ARM and did not compile). Finally I managed to get it to work with tslib, but that had to be compiled from source and patched with egalax patch. Tslib that I installed by apt-get did not work with my panel.

Here is the result:

(Not the best calibration in video, managed to get perfect result after making video).

Really cool, but I suggest a larger screen and touching panel.

Great job!

By any chance, is that ribbon connector compatible with this LCD?

I have 3 of them (from old blackberries at work) and I want to use them for future RPi builds. I can't tell from your picture or you youtube vid, but it looks like it has the right connection.

Thanks by advance !

I have a 3,5" screen at 640x480, but I'm having a hard time actually hitting that resolution. With my overscan options at -18 top and -18 bottom, I get about 648x456. Any tips? :)

Hey alanrpi, im looking for more information on this setup you have going.

Ive seen the price and item list you posted, was there anything else that was required that wasnt included with those items? How easy was it to get the display to function correctly with the R-Pi, plug and play? or electronics fiddling required?

I was looking forward to you posting more detailed information in a video that you commented on somewhere. But wasnt able to find anything apart from your ID thing.

Cheers!

Nothing else was needed. LCD had its own controller and cables included.
4-wire touch panel needed 4-wire touch controller, as you can see from list.
I only needed 12V power supply for LCD. I took that temporarily from external hard drive.
Ofcourse it took few hours on ebay to get right things - I wanted all to be as 'plug-and-play' as possible.

How responsive is the 4-wire resistive touch? Is it quite a hard or soft press? Obviously it wont be like the capactive touch that we are all used to now with phones/tablets. I'm wondering whether you would be able to so some gesture recognition (swipe from side to side, pinch to zoom etc...)

Hi

I've been trying to set up my touch panel (the same as you use) but I'm not a Linux guru. Could you please send me some instructions to help me on the way? My email is janrik @ gmail.com. And I can say, amazing work! :)
