**`CIRQUE_PINNACLE_ATTENUATION`** is a measure of how much data is suppressed in regards to sensitivity. The higher the attenuation, the less sensitive the touchpad will be.
|
||||
|
||||
Default attenuation is set to 4X, although if you are using a thicker overlay (such as the curved overlay) you will want a lower attenuation such as 2X. The possible values are:
|
||||
* `ADC_ATTENUATE_4X`: Least sensitive
|
||||
* `ADC_ATTENUATE_3X`
|
||||
* `ADC_ATTENUATE_2X`
|
||||
* `ADC_ATTENUATE_1X`: Most sensitive
