RE: eGalax touchscreen calibration
I was thinking of a window's 8 style skin, perfect for touchscreens =)

RE: eGalax touchscreen calibration
I have emailed Merlijn, creator of uinput-mapper, he is adding some changes to the code and advising the best way to create a 'config file' including the changes I have made for the egalax TS.
I now read the data from the ts_calibrate 'pointercal' file, just need to clean a few things up, with help from Merlijn and then can provide details of my solution cheers mark |

RE: eGalax touchscreen calibration
Aka, no more messing with swapping values orso?
You read ts_calibrate output, and then create a config file by yourself? Because my values where not on the given point. Italic is your position of the config values, bold are mine Center : X = 1002 Y = 1025 -76.956787 0.700770 0.000343 -55.800903 -0.012320 0.420659 XBian Skin Beta Testing Clock Screensaver If you liked my help, click on "Thanks" to show your appreciation. |

RE: eGalax touchscreen calibration
Those are the values dumped on screen, and not the values inside etc/pointercal file. The ones in the file are different
file contents looks like this 42243 -174 -1212176 -45 25869 -4009392 65536 1280 720 values and equations are xscale xymix xoffset yxmix yscale yoffset scaler Xs = (Xt*xscale + Yt*xymix + xoffset)/scaler Ys = (Xt*yxmix + Yt*yscale + yoffset)/scaler |

RE: eGalax touchscreen calibration
FEEDBACK: It's late I know....for me anyway
I have made a .deb file for ts_calibrate with some mods.... tslib_1-1_armhf.deb (63 KB) https://mega.co.nz/#!jY8inK5I!bPop2Da3NqXVVrniElhL_3ArVv8V24oAvnbPJTUEcGs typing.... Terminal sudo dpkg -i tslib_1-1_armhf.deb should install ok.... Next download the bash script ts_calib.sh and edit /dev/input/event# number to the touchscreen device on your system ...hence Terminal nano ts_calib.sh Terminal #!/bin/bash export LD_LIBRARY_PATH=/usr/local/lib export TSLIB_CONSOLEDEVICE=none export TSLIB_FBDEVICE=/dev/fb0 export TSLIB_TSDEVICE=/dev/input/event2 <-----------*********CHANGE export TSLIB_CALIBFILE=/etc/pointercal export TSLIB_CONFFILE=/usr/local/etc/ts.conf export TSLIB_PLUGINDIR=/usr/local/lib/ts ts_calibrate Now run the script.. Terminal sudo sh ts_calib.sh Hopefully now you have a pointercal file in /etc which will be necessary for the next part.... TBC |

RE: eGalax touchscreen calibration
Hi!
I am the author for the eGalax fixes and I have made some new patches for XBMC12.2(download link). It was tested with the following scenarios: 1. Raspbian OS(2.Feb.2013), custom kernel 3.6.11(with eGalax module), XBMC 12.2 2. XBian 1.0 Beta 1 In both cases touch screen was working fine, which means: - good calibration - click with a single tap - drag(scrollbars) To achieve this you will have to build XBMC either on Raspbian or on XBIAN systems. I will try to make an image and post it and also a video. Information about the build process can be found at: http://www.engineering-diy.blogspot.ro/2013/02/raspberry-pi-raspbian-xbmc-and-egalax-7.html Koenkk, can you please add this fix to XBIAN? Regards, Andrei |

RE: eGalax touchscreen calibration
This is good news, although hard-coding a solutions can have side-effects on other device functionality, please correct me if I'm wrong?
I understand it applies the calibrations to the pointer position (if egalax or calib file exists), but will the 'patch' change the click and drag functionality? even when using mouse, or my alternative method? not sure it will suit all, unless you have the option to enable/disable cheers mark |

If we want it buildin in xbian then we have to make such an enable/disable touchscreen module.

Mouse generates relative events (REL_X, REL_Y) which are not affected. click vs drag: I don't think this will be affected, because what this patch does is when user issues a press event(and XBMC will get alot of events for a single tap/click) the first touch is being ignored and when the second touch comes this is not ignored any more and distance from the previous touch is calculated and XBMC decides if it is a click or a drag action. So I don't think this will affect mouse more than loosing the first press event(but I don't think somebody can click as fast as this can be observed). More details about this implementation can be read on my blog post,part 5: http://www.engineering-diy.blogspot.ro/2013/02/raspberry-pi-raspbian-xbmc-and-egalax-7.html Regards |

RE: eGalax touchscreen calibration
Ok Andrei, I must test it again, since the 'click' didn't work for me originally (MOUSEDRAG issue). Maybe if you post an *.img file I can check.
Originally, your calibration patch worked but the the 'click' function wouldn't at all, hence why I removed it and used the calibration only with the modified patch, I then looked for a more automatic calibration solution (ts_calibrate) to provide a calib file, BTN_RIGHT and 'single press' functionality at input-event level outside XBMC. If your new 'patch' is permanently added then my solution will not work since you will affect my touchscreen behavior internally in XBMC. I think it might be better to give the 'user' a choice somehow whether or not to use the hard-coded solution, if it is to be permanently patched. |

I will try to upload my image as soon as I go home(in about 3 hours). Best Regards, Andrei |

RE: eGalax touchscreen calibration
Maybe you can set a value in your calib file and only use your code if this condition is set? Then there is a choice for the user.
I would still like to use my solution at the moment, it gives me the control I need, I can change code easily without touching XBMC and it doesn't affect anything for anyone else. Plus it will work for future releases of XBMC, version 13 being round-the-corner. |

I just installed your method, although calibration was done, there is a small offset to the left. Everything else works! Right click, normal click. So where can i change the calibx value?
