Hi,
You need to invert the READ_X and READ_Y calls in drivers/input/
touchscreen/ads7846.c for the ts->read_x and ts->read_y values. This
is a well known OmapZoom issue with Android.

Hi,
How can I get calibration with android? The value returned by driver
seemed too big to be used directly.

in your touch driver ,you should set the x/y/pressure's MAX value and MIN
value,the android according to the MAX and MIN value to calculate your
inputing values

hi all,
We have ported android on the ARM9 based board. We are able to see the
home page after booting android on target. But the touch screen is not
working. The touch screen driver is modified to pass the of X,Y
pressure as shown below.
xtmp = (axis_table[2] + axis_table[0]*
when you init your touch driver,you should set some params
as below
input_set_abs_params(codec_ts_input, ABS_X, X_MIN, X_MAX, 0, 0);
input_set_abs_params(codec_ts_input, ABS_Y, Y_MIN, Y_MAX, 0, 0);
input_set_abs_params(codec_ts_input, ABS_PRESSURE, PRESSURE_MIN,
PRESSURE_MAX
hi
init of touch screen driver already has the code mentioned by you. i
am passing the MIN and MAX values for x,y and pressure as shown
below..
#define ADC_MAX ((1 << 12) - 1)
input_set_abs_params(data->idev, ABS_X, 0, ADC_MAX, 0, 0);
input_set_abs_params(data->idev, ABS_Y, 0, ADC_MAX, 0,
Hi Vishal,

Hi,
the input framework depends on a working power driver.
without an enabled android power driver, the framework will not
handle the input-events correctly and constantly report x=0,y=0 as
the location of the touch event.
so either enable the android power driver in the kernel, or dig yourself
i
Hi Patrick,
Thanks for the response . I have PM disabled in the kernel . Will
checkout enabling it.
Thanks
