>1. When the touchpad works by setting pin's direction=out, you could see lots of "no data" message ("IRQ triggered but there's no data") keeping popping up after moving your finger away from the touchpad, am I correct?
no, wrong. when run : echo out > direction,
dmesg say :
[ 133.854926] i2c_hid i2c-MSFT0001:00: i2c_hid_get_input: IRQ triggered but there's no data
only one time,
then my touchpad can work.
no keeping popping up after moving your finger away from the touchpad.
it's only one line .
>2. When pin's direction=out, does only one new "no data" message or multiple ones appear on the screen when you toggle the pin value?
when run : echo out > direction,
dmesg show one time no data msg.no more,
then change pin value,to 0 or to 1,
no msg output.
but ,when value = 1, touchpad not work,
when value =0,touchpad can work.
