imx 53 touch controller issue

[seetha]

Dear friends,

I am working on imx53 BSP. Everything is working fine except the touch.I am using 4-wire MAX 11801 touch controller with I2C communication.This touch controller is working too slow.I mean it takes a lot of time to open a icon on which i click.It prints X,Y position of the screen when I touch the screen.It is not properly displaying the prints that I have put in IST.Please help me out to solve this issue.I have also attached the touch controller code along with this.

Thanks in advance,,

Hi,

I am facing problem with calibration.The touch hardware can calibrate itself.No need of any TCHcal.dll

In registry i am loading only streamdriver.dll(PDD) and Tchproxy.dll.But TChcal.dll is getting loaded and it is calibrating to default values.The problem with this I need to touch some other place to select a particular item.How to remove tchcal.dll completely

TIA,

Nithin

Can you use the max11801 driver in our latest 2.6.35 branch ?

I tested this driver works well.

So I suspect your driver which provide by vender was not works very well.

Thanks.
