Need help with swapping portrait touchscreen axes on a 19"

Fri Apr 08, 2016 4:15 pm

I found a great 19" touchscreen (that just works when you plug it in to the Pi 3 with an unalterd system) on ebay at http://www.ebay.com/itm/BK-SEMS-19-Touc ... Swv9hW3dCh, but I want to run it in portrait mode.

I managed to add a line to /boot/config.txt to turn the screen 90 degrees, but the touch interface naturally did not follow. I found drivers for redhat, Ubuntu & Fedora here: http://www.inexio.co.kr/07_download/download02.html but I don't really know enough to utilize them.

I obviously want to swap axes on the touchscreen, but any tutorials I've found were for the smaller official touchscreens.

Since the driver was already there, it seems to me that swapping the axes would be a feature of that driver, but I cannot discover what it is. I pulled a lsusb and found it listed as port 5, dev 6, class=hid Driver=usbhid, 12M (verified by removing and re-adding it).

I really need to turn that touchscreen for a kiosk demo we're building for a show on the 17th of April, 2016.
We can go landscape if we need to, but our hearts are set on portrait! Can anyone help on this? Thanks, groovy Pi people!

FYI $100 is kinda high for a used monitor IMO.

There is a computer store (A1Computers) that sells used dell 19" monitors for like $15-$30 and will ship (is my understanding). I called them, and they have 100's of monitors in stock. 1 yr replacement warranty.
see: viewtopic.php?f=29&t=138840

I would never pay $100 for a used 720p monitor for a pi, but that is just me.

Are these touch screens which is what the OP was talking about.

Ahh... Yeah I don't know if they sell the touchscreen capable monitors (my bad). Wasn't something i was in the market for. I doubt it though (I somehow didn't even pay attention to that 'touchscreen' part).

Well, in any event, looks like he got the Kiosk up and running (if even only in landscape mode).

Well, thank you for your opinions, but the post is really about needing help with making the monitor portrait mode on the touchscreen. I still need some help with that... I'll change the post title if I can, as it seems like it's confusing.

See and rest of thread: viewtopic.php?p=228403#p228403

This worked for me for display, pi B under Jessie, but I don't have touch support, add to config.txt:

display_rotate=3
gpu_mem=128

Hey, thanks. As I originally posted, "I managed to add a line to /boot/config.txt to turn the screen 90 degrees, but the touch interface naturally did not follow."

I did the display just fine. It's the TOUCHSCREEN I'm trying to turn. I need to swap the axes. The other info (that seems to get in the way of people understanding what's needed) is additional info to help work out the solution. I haven't gotten any further than that. This is going to take a GURU who knows, or can figure out, just what driver in a current Raspian install is already supporting the touchscreen and tell me how to do the axes swap, if it can.

I gots to turn that TOUCHSCREEN INTERFACE! :!:

I bought the 17" BKSEMS and connected it to Raspberry3 running FullpageOS, a version of Jessie. The touchscreen doesn't work. Is there anything else I need to configure to enable it?
