At my project need support Multi finger interactive.
For example the panel have 3 button:
the function of button A is increase the valume,
the function of button B is increase illumination of screen,
the function of button C is play music，
For customer requirement document, We need support 5 finger interactive for different function at the same time.
But actually at the board test, when i press button A and button B at the same time, It have 50% chance that button A and B function can't be triggered at same time.
At the board test, i add EW trace log that include time tick. When trigger Touch Down or Touch Up event, log systerm will output event information and time tick.
When button A and button B OnPress event happen, output event information and time tick.
For the log information, i find the two button trigger normally once and can't trigger once，maybe cycle the trigger and not trigger process.
But when i simulate this problem on PC，button A and B can trigger normally every time.
Why on board test different with simulate on PC？
what cause the on board test problem？
And at the on board test log information i find this：
1、when the two Touch_DOWN event interval time more than 50ms，button A and B can trigger normally every time
2、when the two Touch_DOWN event interval time is 0ms (trigger at the same time), button A and B can trigger normally every time
3、when the two Touch_DOWN event interval time less than 50ms，button A and B can't trigger normally every time
For last question, I know the default one touch event check time is 50ms, but i can't understand the relationship on it.
And i want to know the board test problem rootcause
Note：another information： my project have a Quike Gesture: if two finger slide on the screen need present dialog a new penal
3、when the two Touch_DOWN event interval time less than 50ms，button A and B can't trigger normally every time
At test case 3: the two finger touch been make sure to a 2-finger-slide event?
