still do not work
my init code is
__set_bit(EV_ABS, codec_ts_input->evbit);
__set_bit(EV_KEY, codec_ts_input->evbit);
__set_bit(ABS_X, codec_ts_input->absbit);
__set_bit(ABS_Y, codec_ts_input->absbit);
__set_bit(BTN_TOUCH, codec_ts_input->absbit);
__set_bit(ABS_PRESSURE, codec_ts_input->absbit);
and when pen down
if((x == 0)&&(y == 0)&&(pressure == 0)){
x = last_x;
y = last_y;
} else {
x = ((x- 80)*480)/(1300-80);
y = ((y - 380)*640)/(1600-400);
}
input_report_key(ts->idev,BTN_TOUCH,1);
if (x != last_x) {
printk("the input x value is %d\n",x);
input_report_abs(ts->idev, ABS_X, x);
last_x = x;
}
if (y != last_y) {
printk("the input y value is %d\n",y);
input_report_abs(ts->idev, ABS_Y, y);
last_y = y;
}
if (pressure == last_press)
pressure--;
printk("the pressure is %d\n",pressure);
input_report_abs(ts->idev, ABS_PRESSURE, pressure & 0xfff);
input_sync(ts->idev);
when pen up
printk("input the release event \n");
input_report_abs(ts->idev, ABS_PRESSURE, 0);
