Data Ready (DR) GPIO pin. The DR pin is connected to Pinnacle HW_DR
|
|
which is active high when SW_DR or SW_CC are asserted. If connected
|
|
directly, the MCU pin should be configured as active low.

description: |
|
|
Data output mode in which position is reported. In the relative mode
|
|
each position is reported as relative to the last position. In the
|

idle-packets-count:
|
|
type: int
|
|
default: 0
|
|
description: |
|
|
The number of empty packets where both X and Y are set to 0. They are
|
|
started to be sent when a finger presence is detected missing (no touch
|
|
detected) every 10 ms. They are stopped to be sent when a finger presence
|
|
it detected. An application can count these packets in order to detect
|
|
taps. When set to 0, no empty packets are sent. Supported values from 0
|
|
to 255.
