Happy new year to all at the FTC community ! thankfully and with help from many here ( as well as a little detective work ) I finally have the Tx-Pi working with a responsive touch screen. this is great news and will be a fantastic birthday present for our young son next weekend. as this screen ( Ga...

You definitely have an odd set of Displays there. While I am sure the PCBs are the same as genuine Waveshare displays (they usually do 1:1 copies) the touch layer they use on top of the display may vary. What does the vendor say which driver to use? Edit: It's /usr/share/X11/xorg.conf.d/99-calibrat...

[...] the issue I had is that the touch axis are wrong though USB mouse and KB work fine Just in case you don't already know: TX-Pi provides access via VNC (enabled by default), you don't need physical access to your device. Use the following URL http://IP-ADDRESS-OF-YOUR-TX-PI/remote/ and you can ...

Maybe you can give the "Config" app a try: "System" -> "Config" and then use the "Hamburger button" to select "Display". Use a different value for the "Rotation" value and restart the device. Anyway, I'd be more interested in your experience with the Config app. ;) Best regards, Lars Hi squid, than...

Hi Squid & Master. Have made some progress and now have a new screen 3.5" this is a "garsent" Raspberry Screen, 3.5 inch 480x320 TFT LCD Touch Screen HDMI Monitor for Raspberry Pi. its meant to be waveshare but its actually looking more like an Elegoo https://www.elegoo.com/products/elegoo-3-5-inch-...

Hi master have tried to power the pi directly via microusb ( instead of via the hat) but unfortunately doesn't seem to make a difference Tried your code pi@tx-pi:~ $ dd if=/dev/zero of=blank.eep bs=1k count=4 4+0 Datensätze ein 4+0 Datensätze aus 4096 bytes (4,1 kB, 4,0 KiB) copied, 0,00122937 s, 3,...

thanks masterofgizmo, really hope you can help isolate the cause . I don't have a different screen but may try to buy one if you think this is issue, just didnt want to spend on an older A or B model if these high speed MHS versions are an improvement I was wondering if the hi speed SPI could be par...

How to fix SSH access if its is broken on the TxPi Image logon to the console ( either directly via a hdmi screen and keyboard or via VNC) SU Switch User to an user with admin rights ( FTC user doesn't have root access) check the status of SSH using sudo service ssh status you will probably see some...

unsure if the any timing difference could be that critical. i have up loaded a video here and you can see that occasionally it does detect the touch ( when im tapping rapidly ) With HAT - touch issues - https://www.youtube.com/watch?v=tS9VARmAcrs Same system OS+script - touch working without hat htt...

Hi Lars, Sorry the link doesn't work, Yes its the 3.5 MHS screen I used the correct sh script as you suggest from Squid/Lars ------We noticed a couple of issues with more recent kernels and touchscreens so we recommend an older kernel. output of uname -r shows 4.19.118-v7+ is this as expected ? one ...

So if you use the ft-HAT, then the touch stops working after some time. If you don't use the ft-HAT then the touchscreen simply works as it should. Is this right? This would be a rather odd relationship since the touch and the display share the same bus and there's not much that can break physicall...

Liebe Mitarbeiterinnen und Mitarbeiter Ich hatte einige Probleme damit, den Tx-Pi zum Laufen zu bringen, aber es ist ein brillantes Stück Kit und Community-Aufwand. Verwendetes RPI-Buster-Image und Skript-Installation, die gut funktioniert und jetzt eine zugängliche Plattform hat. Ich habe immer noc...

Weitere Informationen hier - SSH wurde bei der manuellen Installation von behoben. Verwenden der verfügbaren Images Der SSH-Zugriff scheint nicht ordnungsgemäß zu funktionieren, unabhängig von seinem Status in Raspi-config, den txpi-Systemkonfigurationsdiensten oder der "ssh" -Datei in der Startpar...

Hi Master Thanks for your explanation and although I agree the error message can be a common one ( often cache related) I feel their maybe something else more complex going on here you're right that I'm using a Windows PC but I'm using an app called MobaXterm instead which can integrate VNC and othe...

using an ssh client i try to connect to this ip on port 22 and get an error message Network error: Software caused connection abort i read on some TXT related page that the TXT only lets you access ssh after accepting the request on the screen of the txt, but i see no such request i have tries setti...

thanks for your reply, as you suggest SSH should already be activated it is is shown ticked in the system config services menu However on attempted access, it doesn't accept my connection and throws an error that I don't get when trying to SSH into other raspberry pi's using the standard fresh image...

Hallo ja, ich bin auch ein TX-Pi-Hut-Benutzer, habe einen Himbeer-Pi 3b, auf dem das bereitgestellte Image ausgeführt wird, und SSH funktioniert bei mir nicht. Normalerweise schreibt man mit einem Pi eine kleine Datei (keine Erweiterung) namens "SSH" auf das Bootdrive der microSD-Karte, und dann lie...

Hi EstherM, thankyou for trying to reach me, unfortunately i couldn't receive any "activation" emails to either a hotmail or Gmail address, their was no mails in the spam folder and without registering there seemed no way to reach you. lucky I have set up a new email ( just for this forum) and impre...
