Hello everybody,
I was thinking about attach a serial LCD with some push buttons to my Carambola project for doing simple configuration task. But for less than a half you got a touch lcd screen, even one Spi enabled.
Obviously is very different drive an i2c character lcd than a Spi graphical one.
I surfed looking for options and found the great work of Sprites Mod (http://spritesmods.com/?art=spitft) for “Connecting an LCD to a non-video-capable Linux” but seems that He reconfigure the kernel to use the LCD through the standard graphical frame buffer, allowing work whit the X system.
But if you want only a push button with a text box, maybe for enable and disable the wifi with a different SSID, there is not a lot of overhead for our little system?.
Somebody knows a library for paint some simple objects (textbox, label, push button, slider …) in a connected LCD that I can portate? (Don´t forget the touch screen, event driver if possible, je,je ,je)
Any suggestions would be welcome,
Jose.

After a full Web surfing weekend, I’ve only found one free project, “Embedded GUI, http://sourceforge.net/projects/embeddedgui/” and one more free for private use, “MiniGUI , http://www.minigui.org” that meet at least some of my expectations.
For now, I have not managed to work well either of them, seems to be dead projects.
But I found many commercial projects them seems very pretty, I'm a little afraid, anyone can give me some hope?

Maybe http://picogui.org/index.html will be enough good ?

Finaly I managed to run MiniGui (was Java version) , runs over eclipse, has a good GUI designer but the little documentation was basically in Chinese, and I have not managed to find out how code the fisical layer.

I've also looked two commercial programs, Gem Studio (http://www.amulettechnologies.com/) and Crank Storyboard (http://www.cranksoftware.com/), impressive both, especially last one. Both are developed to provide a complete solution, but despite that claim to compile for Linux, obviously not are their main markets. I have not looked the prices because my first goal is that the touch screen must be around 20$.

I feel like I have to reinvent the wheel.
