Query regarding Touchscreen for RPi 3 running Debian Jessie

Why ever not?

At worst it'd just be a driver issue.

My Hardware is: RPi 3B, Official RPi 7" Touchscreen, SmartiPi Touch Enclosure, 32GB uSDcard (w/ Raspbian 2016-05-27). Put together 31JUL16 (this was b/f the intro of Raspian w/ Pixel-desktop).

Latest Raspian-Debian SHOULD Work. There are other Discussion Threads here at element14 community, where I have posted info on my Setup. I will give URLs if anybody wants to know. Please include your Country of Residence so I can have an idea of what may/may-not be available where you live.

Official Raspberry Pi Touch Screen will certainly work with Raspbian Jessie. But you didn't specify if it was that one or another touch screen.

My 7" touch screen was one gotten from element14.com, Stock # 49Y1712 Manf p/n RaspberryPi-Display, 7", $60.00 (USD)- 28JUL16

Yes, but we need to know what the original poster has, in order to be able to answer his question accurately.

Thank you for you input, I'm planning on buying a smaller 2.8" TFT Touch Screen like this one.

A 2.8" Display is Cute, but using the Virtual (on screen) Keyboard might pose a problem. On my 7" Display, the virtual Keyboard is barely use-able. BTW when I connect both a USB Mouse and USB Keyboard, BOTH the virtual I/O device(s) WORK Concurrently w/ the USB-Counterpart(s). Pretty-Cool.

It really is! A 7" display would provide a lot more real estate to play with, but I'm trying to keep the footprint as small as possible. I don't plan on using the display for development procedures as such. It's for a home automation project I'm working on. I'll be designing a GUI in Tkinter to display on the available video output.

Well, you don't say which type of touch screen you are thinking of buying. I use the type which has an HDMI screen and a USB touch screen interface. I upgraded from RPi2 to RPi3 and there were few problems other than the usual config file tweaks.

I use the RPi in my products and that's the reason I use the HDMI/USB form as I am sure it will always work - even RPi4! Implementations that use the DSI port or SPI for the video will always have more of a dependency on the driver files being updated. The USB touch screen is also standard in Linux and only needs calibrating usually.

If this is a one-off project then most of the LCD touch screens available should work on RPi3 and will say so in the documentation. Certainly the official screen does work as I have colleagues that use it.

As most of my software is written in Python I use Kivy for the GUI. The nice thing about Kivy is I can develop my software on my main PC and it will run unaltered on the Rpi target. Yes, you can use Tkinter or QT, but Kivy is worth a look before you cut too much code.

To DG. Nice post. You are spot-on w/ your comments concerning what are the Aim(s) of SW's project. Here, Form follows Function. A 2.5"er is more appropriate for him. DG (you) wrote>>...I use the HDMI/USB form as I am sure it will always work - even RPi4!...

USCDADNYC Reply>> Yes, HDMI is more Universal than the SW's 2.5"er. But HDMI is Not Touch Screen. I got the best of both worlds. W/ my SmartiPi Touch Enclosure, I used a Dremel Tool to cut-away Access to the HDMI Port. Then used a Right-Angle HDMI-HDMI-Adapter. BTW RPi4? Do you know something, we don't. BTW2 I have on-order a Pi-TopCREED. for my next project. A Prototyping enclosure for possibly (a) RaspPiZeroW, (b) UP board (not UP^2 board), (c) RPi4(?) if form factor is not bigger than RPi3B. This Pi-TopCREED has a HDMI/eDP-to 14" LCD Display inside it.At least I think so. I will know better when I receive shipment.

USCDADNYC Reply>> What USB Touch Screen? the official RPi 7" touch screen (element14.com, Stock # 49Y17120)?
