Calibration after Cold Boot

I´ve been seeing in support.symbol.com that there is no way to remove the Calibration Screen after a Cold Boot.
I have a .reg file that is being using for autocalibrate the screen every time a Cold Boot is made.
What do you think about removing the calibration screen?

 Hi Pablo,

I had a similar problem but in a MK500, try to use this program.... put in the Application directory and after create a .run file in the start up directory that call this exe.

or create this .reg



[HKEY_LOCAL_MACHINE\HARDWARE\DEVICEMAP\TOUCH]
"CalibrationData"="that you need", this is the mk500 "2070,2065 3174,970 3189,3167 950,3217 935,970 "
"MaxCalError"=dword:0000000a
"PowerUpTouchDelay"=dword:00000fa0


[HKEY_CURRENT_USER\Software\Symbol\Startup\Configurations\Touch]
"ForceCalibrate"=dword:00000000

Hi Pablo,



Please try use this reg file. Put in application folder and then cold boot.





[HKEY_CURRENT_USER\Software\Symbol\Startup]

"SkipCalibrate" = dword:00000001

[HKEY_LOCAL_MACHINE\HARDWARE\DEVICEMAP\TOUCH]

"CalibrationData" = "503,509 797,794 217,793 219,213 795,223 "

Hi I have two MC3090 right

Hi
I have two MC3090 right now with this values:
520,507 811,798 236,798 240,215 798,210

510,508 783,785 223,785 216,210 789,218

They are similar but not the same, so what happens if I put always the same value to a large number of MC3090. It seems each device has his own TOUCH config.
I think the touch screen in some devices could be wrong. Am I wrong?

There are always variations

There are always variations to each touch screen.  That is why calibration is needed.  Keep in mind that calibration is not only device specific but user specific.  A left handed user's calibration in a lot of cases would be different from a right handed user.  Similar differences can be seen between users who hold the unit more horizontal versus vertical.







Someone at Motorola could speak better to the variations introduced during the manufacturing process.

Hi Pablo, in fact the number

Hi Pablo,
in fact the number in the registry key describes the pixel position in Y-X form of each calibration cross as it appears when you make manual calibration:
the screen should be considered as upside down ( physically 180° rotated), so the exact position should be normaly 510-510 ( center cross) , 800-800 ( upper left cross ) to 800-220 ( upper right cross )

as said previously , the touchpad could not be strictly the same for each pda , every calibrating people as it's own angulation for reading and typing so ...
a position error of 20 pixels on a 1020 pixels screen is under 2% .

You are saying that the screen has 1020 x 1020 pixels?
Why when I go to System Info in the Display Tab it says Horizontal Res: 324 Pixels, Vertical Res: 324 Pixels.
What is the relationship between these values?
