Hello Arno,

Congratulations with the Touch screen project. I really love it! It works very well, stable, and infinitely adjustable .

I was just browsing the ebay store from where we get our screens, and I was just looking at this picture



And I see on the bottom also icons for the home, monitor/download and lock screen buttons. Would it be possible for us to place icons there as well? This would make navigation for newbies easier I think.

Greetings,
Erik

Hello Erik,

I think you need to partly disassemble the TFT module to place icons into this touch sensitive extra area beside the TFT matrix. Currently, the assignment of the three functions "Home", "Setup" and "Screen lock" is fixed. These functions are always available independent of the loaded project and the active page. Technically it would be possible to assign additional functions here, but I think for newbies they are hard to control, since the sensitive area is very narrow and you need to hit it very accurately. As this extra touch area is not available on the "big" TFT modules, I consider to provide Button functions for "Setup" and "Screen lock", which can be placed freely by the user. This would provide you an alternative to the extra touch area for the small displays.

However, which additional functions would you think of?

Best regards,
Arno

Hello,

I was not thinking about additional functions, just to have a icon to touch instead of a black screen. However, I did not realise that there where no pixels on that part of the screen to generate a icon. Placing the icons there manually might be tricky... Anyone up to try this out?

It is a good idea I think to be able to place those options freely on the screen. In that case it is even possible to cover the black part of the screen, than newbies will not be able to touch it accidentally.


There is also a 7" screen available in the ebay store, any plans using it as well?

Hello Erik,

no, currently I have no plan to support the 7" Display. Technically it could be feasible to attach it via an adapter cable. I could try to get it running, if you would borrow one to me.

Arno

Ahh yes, taking a closer look and indeed the pinout is different on the 7" screen.
There is no particular reason for me to use the 7" display, but I can lend you one to help expand the project.
However, there is no need to go trough all the trouble just for me. For me the 5" screen will be brilliant as it is.

Also, I can imagine that the hassle will become bigger and bigger once you will support more and more screens

Hallo,

hier ist die neue Software: Editor V1.50 und Firmware V1.0. Eine nähere Beschreibung ist im Wiki. Dort lassen sich die Dateien aber momentan leider nicht hochladen. Ich werde das nachholen. Neben hoffentlich nicht notwendigen Bug-Fixes werde ich als nächstes die Doku nachziehen und den Sourcecode kommentieren und veröffentlichen.

Hello,

I think there is a bug in the new software, my background is all messed up. Here are 2 pictures to illustrate my problem.
Everything else still works good

Arno hat wieder mal eine neue Version seiner Software (Firmware und Editor) veröffentlicht.
Die neue Funktionen 3 bis 8 wurden von mir getestet.
1. 5" Displays
2. externe Tasten
3. Setup Seite und Screen-Lock als Sprungziele für Jumper
4. automatischer Sprung für Jumper
5. File-New funktioniert jetzt
6. Sicherheitsabfrage beim Öffnen von Projekten,
wenn das aktuelle noch nicht gespeichert wurde
7. Rechter Mausklick auf Jumper im Editor springt auf Zielseite
8. Temperaturoffset für Temperatursensoren zur
Verbesserung der Messganauigkeit möglich
Zu 1.) keine HW vorhanden
zu 2.) Duku zum Anschluß der Tasten fehlt noch.
Vielen Dank an Arno für die Weiterentwicklung von LCD Touch!

Hello Erik,
do you install the new firmware "EIB_LCD_0x32024002_10.bin" and do you export your projekt with the new projekt editor "LcdEditor_1.50.jar" and put it in your LCD Touch (via SD-Card)??
Hans

Hello Erik,
I'm sorry, but currently I can't reconfirm your issue (which doesn't mean there is no). I know this effect happens if a picture overlaps the screen borders, but the Editor should prevent this. It would help me a lot if you could sent me a test case, which I could use to debug your issue.

Regards,
Arno

Hallo Hans,
die Doku ist jetzt auf der Hardware Seite im Wiki.

Arno

Hello Erik,

please check for the firmware update V1.1 on the Wiki pages. The issue was related to a modification for supporting larger displays. I'm sorry it took some while to fix this issue. The binary project compiled by the editor is ok. It means all you need to do is updating the firmware.

Arno

All is working well again Arno!

Great updates, thanks a lot

Hallo Arno,

hast du noch Platinen und Bauteile.
Würde gern ein Display aufbauen.

Gruß
Mario

Hallo Mario,

eine Platine kannst du gerne haben. Das Xilinx CPLD und den ATMEGA könnte ich dir vorher auflöten und programmieren, wenn du keine entsprechenden Programmer hast. Im Allgemeinen macht ein Beistellen der Einzelteile für das Board keinen Sinn, weil abzählen und verpacken der SDM Teile fast so viel Arbeit wie das Auflöten ist.

Arno
