Hi QNX, qnx sdp 6.6, qnx sdk for apps and media 1.1 release, BSP_ti-am335x-beaglebone_br-660_be-660_SVN797070_JBN574.zip beaglebonedemo.ext.anm11.258.150325_2017 touchscreen 800x480 I am working on touchscreen with beaglebone black on qnx 6.6. Touchscreen starts with calib-touch 3-point calibration. However it stuck at the last step as described in Figure 4, http://www.qnx.com/developers/docs/6.6.0_anm11_wf10/#com.qnx.doc.neutrino.utilities/topic/c/calib-touch.html exactly same situation as previous post, "calib-touch program doesn't accept or recognize that." http://community.qnx.com/sf/discussion/do/listPosts/projects.graphics/discussion.advanced_graphics.topc25633 After many times tries, calib-touch finally "accept" and save the data to calib.localhost. However, the calibration is not accurately at all. You have to estimate and try to figure out exact location, for example, in QT keyboard demo program from beaglebonedemo, push "2" maybe come out "8", very frustrating. Please advise, thanks in advance Mike
another issue, after the first unsuccessful "accept"ed calibration, I tried to do recalibration with calib-touch -zorder=20 -config-file=/tmp/calib.localhost -recalibrate this time stuck at Figure 1 of http://www.qnx.com/developers/docs/6.6.0_anm11_wf10/#com.qnx.doc.neutrino.utilities/topic /c/calib-touch.html i.e., the target never moves no matter touch any place on the whole screen. It seems, the previous calibrated data were still in use, and blocked the recalibration. Please advise, thanks in advance. Mike
never mind, use legacy driver "devi" instead of "hid" solve the problem. Mike
