touch_at_status
Output structure received as part of the Autonomous QTouch Interrupt callback
function.
Data structure which holds the status parameters for the autonomous QTouch
sensor.
touch_qm_dma_t
Input to the touch_qm_sensors_start_acquisition() API.
Data structure which holds the DMA channel information for touch acquisition
data transfer
touch_qm_pin_t
Input to the library
Data structure which holds the Pin configuration information for QMatrix
Comment
Indicates the DMA channel 1. Can take values from 0 – 11, but should not
be same as dma_ch2
Indicates the DMA channel 2. Can take values from 0 – 11, but should not
be same as dma_ch1
Comment
Bitmask that indicates the selected X pins for QMatrix. If bit n is set, Xn is
enabled for QMatrix; n can be 0 to 17. Any other bits set are ignored. Note:
For QMatrix operation, X8 is not available as it must be used for ACREFN
function.
