calib-touch difficult to work and not accurate
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
