Did you have a similar problem? BTW, I tested under both debian etch arm and lenny armel using the compiled library the way specified in the blog and a package downloaded from lenny repositories. Could be permissions related. However I did compile tslib recently on Ubuntu again and I got that same message.

I might be missing something. In the mean time if you are in hurry I have a compiled binary for the TS that works. I loaded your compiled tslib and chmodded event0 and it finally recognized the device.

This might have to do with the way event0 is sending the data…. Here's an example for this:. This should result in a libts. Alternatively, you can use CMake to build the project. To create building in the project tree:. By default, the core tslib is built as a shared library. Also, the plugins are by default built as shared. The following is a minimal example of how to use tslib, built with CMake, in your client app.

Adding tslib::tslib as a link target will add required dependencies and include directories generated build files. In case you cannot draw directly on the framebuffer, there is an experimental implementation of the necessary graphical tools using SDL2. They are more portable, but require more resources to run.

To use them, make sure you have SDL2 and the development headers installed and use. This is the hardware independent core part: libts and all filter modules as shared libraries , build on the following operating systems and probably more. This makes the thing usable in the real world because it accesses your device.

See hardware support for the currently possible configuration for your platform. The libts default configuration currently has the following input modules disabled :.

Please note that this list may grow over time. If you rely on a particular input plugin, you should enable it explicitly. On Linux, you should only need input though. The ts. Those are to be considered workarounds and may get disabled in the default configuration in the future.

If you use one of those, please. For Linux evdev this is called input. This project exists [ thanks ] to all the people who contribute.

Connect and share knowledge within a single location that is structured and easy to search.

I have a arm based board with embedded linux on it and I believe it has a FT5x06 touch screen controller but seems like tslib has some problems with multitouch capacitive touch screen controllers. I cross compiled tslib with arm-linux-gcc4. And it doesn't accept my touches. Now I think somehow I'm supposed to get tslib to work with the controller as a single touch device but I'm not sure how to do that or which file to change.

Do I have to edit driver file in kernel and rebuild it too? Here is a sample of some environment variables,. Many variables are not needed to run Qt with tslib. The name should be something like FT Touchscreen. The inputX file may change as other input drivers are plugged into a system, such as a USB mouse, etc.

The ts. Here is an example for the 'Focal Tech' device,. Tslib is structured with several modules shared libraries which are loaded dynamically at run time. This was much more useful with resistive touch technology where x and y parameters may inter-mix , including sheering, etc.

Note: it is possible to avoid this calibration step, which is highly desirable if you are manufacturing large quantities. The formula is like this,.
