Raspberry pi interface

For touchscreen, please see:

http://www.valdodov.com/index.php?show=hardware&item=1

If it comes up in Bulgarian, click the Union Flag on the top left then Hardware, 320x240 TFT LCD for the Raspberry Pi.

This is a great touchscreen with good resolution. It is available for $16 (£10) from the sainsmart website http://www.sainsmart.com/sainsmart-3-2-tft-lcd-display-touch-panel-pcb-adapter-sd-slot-for-arduino-2560.html and comes with the touchscreen controller already calibrated.

For the camera, I would recommend the Raspberry Pi Camera:

This is by far the most supported and the code comes as standard as part of Raspbian.

Any questions, let me know

Thank you.

But i am looking for a 7" touch screen module.

What abt the one in the below link

Amazon.com: SainSmart 7" Raspberry Pi LCD Display Touch Screen TFT Monitor AT070TN90 with HDMI VGA Input Driver Board Co…

Amazon.com: Raspberry PI 5MP Camera Board Module: Computers & Accessories

Yeah, even easier.

Just connect HDMI to Raspberry Pi for display and power and USB for touchscreen

Based on the reviews on the amazon page, the touchscreen drivers may be a little tricky to install.

However, on the sainsmart website page

http://www.sainsmart.com/7-inch-tft-lcd-monitor-for-raspberry-pi-touch-screen-driver-board-hdmi-vga-2av.html

There is a youtube video which makes it appears easy to install. Perhaps this is a response to all the feedback.

Interestingly, it works out cheaper to buy it off the actual sainsmart website itself.

Let me know how you get on as I am interested in upgrading my setup to use one of these and would be interested in your progress.

Any problems installing the driver, let me know and I'll do my best to help.

I just found a method of doing the whole thing.

The links are below:

Pi Setup | DIY WiFi Raspberry Pi Touchscreen Camera | Adafruit Learning System

SO instead of that adafruit 2.8" screen kit, I am planing to use the saintmart 7" one in the link below.

http://www.sainsmart.com/7-inch-tft-lcd-monitor-for-raspberry-pi-touch-screen-driver-board-hdmi-vga-2av.html

I guess the same procedure outlined in the links above i.e the software for the camera and stuff should also work for the saintmart one , right ?

What do you think ?

Yeah, sorry for taking a while to reply but I have been thinking about this one as I wanted to provide you with a well thought out answer..

The Adafruit 2.8" screen uses the GPIO pins to control it and the SPI bus to provide feedback from the touchscreen.

The touchscreen you have selected uses the HDMI port for the display and a USB device for the touchscreen.

The screen will work fine, just plug it in to the right port and you may have to adjust the settings to get the correct aspect ratio.

The thing people appear to be uncertain with is the touchscreen.

I have one of these controllers at home so will have a play tomorrow night (first time I'm home, currently out on a job) and see how easy it is.

However, this system looks worth getting, just may take an hour to get the touchscreen working well.

Thank you.

But apart from the hardware interface differences, the software part, i.e the camera application (using the python package) mentioned on the adafruit should work fine i guess. What do you think??

yeah, everything else will work just fine.

Hi sir

I was looking to install this touch screen keyboard, matchbox on the pi.

I wanted to know how do i start the keyboard automatically when raspberry pi RASPBIAN OS boots up or gui loads up. Can anyone tell me the steps on how to do it ?

To install the keyboard use "sudo apt-get install matchbox-keyboard"

To autorun a program after you login. use "sudo nano /etc/profile" and enter the command exactly as you would in terminal at the bottom of this file. From here Raspberry Pi • View topic - How to autorun applications after x starts? it appears the command you need to enter is "Matchbox-Keyboard" so add that to the bottom of the file.

However, permanently having a keyboard on screen may get a bit annoying so using the instructions which can be found here

fetch( ); decode( ); execute( );: On Screen Keyboard for Raspberry Pi

you can create an icon on the desktop which brings up the keyboard meaning the keyboard can be opened and closed as much as you want.

Any problems let me know

Thank you. I am waiting for the screen to arrive.
