Is Your Wiz Touchscreen Accurate?

[sam fisher]

Hi, I was just trying a simple test to see whether the Wiz screen is accurate to draw 1 pixel thick lines without too much "shake" an I found that the further towards the right of the screen I go, the worse the accuracy becomes (it is off horizontally). However, this Wiz is running 0.7.1 and I remember reading somewhere that TS accuracy was improved with the 1.0 patch so I was wondering if someone with a 1.0 Wiz could test this app for me and see how it is (drawing that is).

The controls are Select to clear the screen or B to exit.

Download the test app here.

I have the exact same problem with my retail wiz running at 1.0. Makes it really difficult to play touchscreen games like Boomshine. Once you're on the right side of the screen, it's very difficult to aim correctly.

This could be a issue that effects the whole Wiz or maybe it only effects the Fenix runtime?

Well that sucks. Should be fixable with a refined calibration routine in firmware though, right? GPH just has to do it.

I briefly spoke to Orkie about it earlier and he said it is probably due to a dodgy TSLib.

I tested your app for you, I found that my wiz is very off with the touch screen, about 5-7 pixels off, no matter which part of the screen I touch.

Try recalibrating in the setting menu.

I forgot to mention that I did, its still off. Probably the firmware, I HOPE its not the hardware :/

 

[sam fisher]

It's probably not the hardware. What version of the firmware do you have?

It seems fine for me (Firmware 0.7.1, Wiz from November of last year)

By the way, when you calibrate the touch screen from the settings menu, make sure you keep the stylus pressed on the white rectangles until they turn red, simply touching them and quickly letting them go will not do anything.

hmmm, when i'm drawing it randomly jumps about a bit and hence sometimes strange unwanted lines seem to appear.

Same, i have firmware 1.0

Quick question, the firmware is open source right? Other people can release their own firmwares?

 

[sam fisher]

They can but it is a lot of work (see Open2x for the GP2x).
