How to set GT911 touch data scan interval or interrupt?


2021-04-05 17:15:09

GT911 is used as a touch panel.The problem is that the 0x814E scan cycle is too fast.

And when I touch the panel, the key value is read continuously, so it is a problem. 

I want to know how to generate an interrupt when the key is pressed. 

Tell me where to modify the settings.

And the 0x814E scan cycle is about 70 usec, can I change it to 100 msec cycle?Lastly, please let me know if there is a part that recognizes the coordinates only once when you touch the screen and makes it no longer recognized.

I look forward to hearing from you.

I wish you a happy day.
