Touchscreen Calibration

<!doctype html public “-//w3c//dtd html 4.0 transitional//en”>

I am setting up a sytem with a Microtouch touchscreen, I have encountered the same axis rotation issue mentioned in other messages. The acalib utility appears to write the last  number of configuration file absf.1 as a 1 instead of a 0 which causes the touchscreen coordinates to be rotated 90 degrees. I located two versions of a utility named calib which I have been unable to succesfully decompress, does anybody have experience with calib and does it fix the problem.

Also if anyone knows how to succesfully download .gz files on a windows machine and then transport them to QNX via Dosfsys for decompression using gunzip I would appreciate the input.

I’ve dealt with the acalib program a few times. I’ve don’t
believe that there has been a distributed fix to this problem
yet, so the only solutions are manual intervention or some
type of kludge.

You might want to check into Fatfsys if you are trying to
copy from a hard drive as it supports 32bit FAT, which
Dosfsys does not.

Mitchell,
    Thanks for the response, I have now successfully gotten the calib utility into QNX and tried it out. The utility seems to be a much more visually appealing alternative to acalib and produces a more verbose text output to the pterm window. Unfortunately it also exhibits the coordinate rotation problem. The problem with the utility was just rustiness on my part, I didn't chmod the utility to make it executable. Additionally my Win NT box apparently handled the decompression automatically but left the .gz file extension.

Mitchell,
    A further update, the calib utility appears to create a proper absf.1 file, however it does not apply the rotational change until Photon is shutdown and restarted. If you restart Photon without doing anything else the calibration seems to be OK and subsequent calibrations using calib work correctly, at least so far.

Hi Roy,

Where did you get this QNX4 calib utility?

There are a couple of QDN knowledgebase articles pertaining to the touchscreen issues. QNX.000010340 and QNX.000010350 each contain a link to one of the two calib files. For reference its http://staff.qnx.com/~emuis/files/photon/1.1x/touchscreen

Hi All,

QNX hardware support (Erick Muis) emailed me
this version of calib as well. He told me it was supposed to
be in the QNX 4.25 distribution but was overlooked. Still don’t
know if it has gotten in an official distribution though. It does
work alot better than the old acalib. Seems like QNX ought to
provide this on an ftp site.
